kill.
3.a. The electrode and work (or ground) circuits
are electrically “hot” when the welder is on.
Do not touch these “hot” parts with your bare
skin or wet clothing. Wear dry, hole-free
gloves to insulate hands.
4.b. Use suitable clothing made from durable flame-resistant
material to protect your skin and that of your helpers from
the arc rays.
3.b. Insulate yourself from work and ground using dry insulation.
Make certain the insulation is large enough to cover your full
area of physical contact with work and ground.
4.c. Protect other nearby personnel with suitable, non-flammable
screening and/or warn them not to watch the arc nor expose
themselves to the arc rays or to hot spatter or metal.
In addition to the normal safety precautions, if welding
must be performed under electrically hazardous
conditions (in damp locations or while wearing wet
clothing; on metal structures such as floors, gratings or
scaffolds; when in cramped positions such as sitting,
kneeling or lying, if there is a high risk of unavoidable or
accidental contact with the workpiece or ground) use
the following equipment:
FUMES AND GASES
can be dangerous.
5.a. Welding may produce fumes and gases
hazardous to health. Avoid breathing these

ventilation and/or exhaust at the arc to keep
fumes and gases away from the breathing zone. When
welding with electrodes which require special
ventilation such as stainless or hard facing (see
instructions on container or MSDS) or on lead or
cadmium plated steel and other metals or coatings
which produce highly toxic fumes, keep exposure as
low as possible and below Threshold Limit Values (TLV)
using local exhaust or mechanical ventilation. In
confined spaces or in some circumstances, outdoors, a
respirator may be required. Additional precautions are
also required when welding on galvanized steel.
3.c. In semiautomatic or automatic wire welding, the electrode,
electrode reel, welding head, nozzle or semiautomatic
welding gun are also electrically “hot”.
3.d. Always be sure the work cable makes a good electrical
connection with the metal being welded. The connection
should be as close as possible to the area being welded.
3.e. Ground the work or metal to be welded to a good electrical
(earth) ground.
3.f. Maintain the electrode holder, work clamp, welding cable and
welding machine in good, safe operating condition. Replace
damaged insulation.
5. b. The operation of welding fume control equipment is affected
by various factors including proper use and positioning of
the equipment, maintenance of the equipment and the spe-
cific welding procedure and application involved. Worker
exposure level should be checked upon installation and
periodically thereafter to be certain it is within applicable
OSHA PEL and ACGIH TLV limits.
3.g. Never dip the electrode in water for cooling.
3.h. Never simultaneously touch electrically “hot” parts of
electrode holders connected to two welders because voltage
between the two can be the total of the open circuit voltage
of both welders.
5.c. Do not weld in locations near chlorinated hydrocarbon vapors
coming from degreasing, cleaning or spraying operations.
The heat and rays of the arc can react with solvent vapors to
form phosgene, a highly toxic gas, and other irritating prod-
ucts.
3.i. When working above floor level, use a safety belt to protect
yourself from a fall should you get a shock.
3.j. Also see Items 6.c. and 8.
5.d. Shielding gases used for arc welding can displace air and
cause injury or death. Always use enough ventilation,
especially in confined areas, to insure breathing air is safe.
5.e. Read and understand the manufacturer s instructions for this
equipment and the consumables to be used, including the
material safety data sheet (MSDS) and follow your
employer s safety practices. MSDS forms are available from
your welding distributor or from the manufacturer.

process used and properly operating
regulators designed for the gas and
pressure used. All hoses, fittings, etc. should be suitable for
the application and maintained in good condition.
If this is not possible, cover them to prevent
the welding sparks from starting a fire.
Remember that welding sparks and hot
materials from welding can easily go through small cracks
and openings to adjacent areas. Avoid welding near
hydraulic lines. Have a fire extinguisher readily available.
7.b. Always keep cylinders in an upright position securely
chained to an undercarriage or fixed support.
6.b. Where compressed gases are to be used at the job site,
special precautions should be used to prevent hazardous
situations. Refer to “Safety in Welding and Cutting” (ANSI
Standard Z49.1) and the operating information for the
equipment being used.
7.c. Cylinders should be located:
•Away from areas where they may be struck or subjected to
physical damage.
•A safe distance from arc welding or cutting operations and
any other source of heat, sparks, or flame.
6.c. When not welding, make certain no part of the electrode
circuit is touching the work or ground. Accidental contact
can cause overheating and create a fire hazard.
7.d. Never allow the electrode, electrode holder or any other
electrically “hot” parts to touch a cylinder.
6.d. Do not heat, cut or weld tanks, drums or containers until the
proper steps have been taken to insure that such procedures
will not cause flammable or toxic vapors from substances
inside. They can cause an explosion even though they have
been “cleaned”. For information, purchase “Recommended
Safe Practices for the Preparation for Welding and Cutting of
Containers and Piping That Have Held Hazardous
Substances”, AWS F4.1 from the American Welding Society
(see address above).
7.e. Keep your head and face away from the cylinder valve outlet
when opening the cylinder valve.
7.f. Valve protection caps should always be in place and hand
tight except when the cylinder is in use or connected for
use.
7.g. Read and follow the instructions on compressed gas
cylinders, associated equipment, and CGA publication P-l,
“Precautions for Safe Handling of Compressed Gases in
Cylinders,” available from the Compressed Gas Association
1235 Jefferson Davis Highway, Arlington, VA 22202.
6.e. Vent hollow castings or containers before heating, cutting or
welding. They may explode.
6.f. Sparks and spatter are thrown from the welding arc. Wear oil
free protective garments such as leather gloves, heavy shirt,
cuffless trousers, high shoes and a cap over your hair. Wear
ear plugs when welding out of position or in confined places.
Always wear safety glasses with side shields when in a
welding area.
FOR ELECTRICALLY
powered equipment.
8.a. Turn off input power using the disconnect
switch at the fuse box before working on
the equipment.
6.g. Connect the work cable to the work as close to the welding
area as practical. Work cables connected to the building
framework or other locations away from the welding area
increase the possibility of the welding current passing
through lifting chains, crane cables or other alternate cir-
cuits. This can create fire hazards or overheat lifting chains
or cables until they fail.
8.b. Install equipment in accordance with the U.S. National
Electrical Code, all local codes and the manufacturer s
recommendations.
8.c. Ground the equipment in accordance with the U.S. National

SAFETY
5. Toujours porter des lunettes de sécurité dans la zone de
soudage. Utiliser des lunettes avec écrans lateraux dans les
zones où l on pique le laitier.
PRÉCAUTIONS DE SÛRETÉ
Pour votre propre protection lire et observer toutes les instruc-
tions et les précautions de sûreté specifiques qui parraissent
dans ce manuel aussi bien que les précautions de sûreté
générales suivantes:
6. Eloigner les matériaux inflammables ou les recouvrir afin de
prévenir tout risque d incendie dû aux étincelles.
7. Quand on ne soude pas, poser la pince à une endroit isolé de
la masse. Un court-circuit accidental peut provoquer un
échauffement et un risque d incendie.
Sûreté Pour Soudage A LʼArc
1. Protegez-vous contre la secousse électrique:
a. Les circuits à l électrode et à la piéce sont sous tension
quand la machine à souder est en marche. Eviter toujours
tout contact entre les parties sous tension et la peau nue
ou les vétements mouillés. Porter des gants secs et sans
trous pour isoler les mains.
b. Faire trés attention de bien s isoler de la masse quand on
soude dans des endroits humides, ou sur un plancher
metallique ou des grilles metalliques, principalement dans
les positions assis ou couché pour lesquelles une
grande partie du corps peut être en contact avec la
masse.
8. S assurer que la masse est connectée le plus prés possible
de la zone de travail qu il est pratique de le faire. Si on place
la masse sur la charpente de la construction ou d autres
endroits éloignés de la zone de travail, on augmente le risque
de voir passer le courant de soudage par les chaines de lev-
age, câbles de grue, ou autres circuits. Cela peut provoquer
des risques d incendie ou d echauffement des chaines et des
câbles jusqu à ce qu ils se rompent.
9. Assurer une ventilation suffisante dans la zone de soudage.
Ceci est particuliérement important pour le soudage de tôles
galvanisées plombées, ou cadmiées ou tout autre métal qui
produit des fumeés toxiques.
c. Maintenir le porte-électrode, la pince de masse, le câble
de soudage et la machine à souder en bon et sûr état
defonctionnement.
d.Ne jamais plonger le porte-électrode dans l eau pour le
refroidir.
10. Ne pas souder en présence de vapeurs de chlore provenant
d opérations de dégraissage, nettoyage ou pistolage. La
chaleur ou les rayons de l arc peuvent réagir avec les
vapeurs du solvant pour produire du phosgéne (gas forte-
ment toxique) ou autres produits irritants.
e. Ne jamais toucher simultanément les parties sous tension
des porte-électrodes connectés à deux machines à soud-
er parce que la tension entre les deux pinces peut être le
total de la tension à vide des deux machines.
f. Si on utilise la machine à souder comme une source de
courant pour soudage semi-automatique, ces precautions
pour le porte-électrode s applicuent aussi au pistolet de
soudage.
11. Pour obtenir de plus amples renseignements sur la sûreté,
voir le code “Code for safety in welding and cutting” CSA
Standard W 117.2-1974.
2. Dans le cas de travail au dessus du niveau du sol, se pro-
téger contre les chutes dans le cas ou on recoit un choc. Ne
jamais enrouler le câble-électrode autour de n importe quelle
partie du corps.
PRÉCAUTIONS DE SÛRETÉ POUR
LES MACHINES À SOUDER À
TRANSFORMATEUR ET À
REDRESSEUR
3. Un coup d arc peut être plus sévère qu un coup de soliel,
donc:
a. Utiliser un bon masque avec un verre filtrant approprié
ainsi qu un verre blanc afin de se protéger les yeux du
rayonnement de l arc et des projections quand on soude
ou quand on regarde l arc.
b. Porter des vêtements convenables afin de protéger la
peau de soudeur et des aides contre le rayonnement de
l arc.
1. Relier à la terre le chassis du poste conformement au code
de l électricité et aux recommendations du fabricant. Le dis-
positif de montage ou la piece à souder doit être branché à
une bonne mise à la terre.
2. Autant que possible, I installation et l entretien du poste
seront effectués par un électricien qualifié.
c. Protéger l autre personnel travaillant à proximité au
soudage à l aide d écrans appropriés et non-inflamma-
bles.
3. Avant de faires des travaux à l interieur de poste, la
debrancher à l interrupteur à la boite de fusibles.
4. Des gouttes de laitier en fusion sont émises de l arc de
soudage. Se protéger avec des vêtements de protection
libres de l huile, tels que les gants en cuir, chemise épaisse,
pantalons sans revers, et chaussures montantes.
4. Garder tous les couvercles et dispositifs de sûreté à leur
place.

SPARK ARRESTER
Gasoline engine mufflers may emit sparks when the
engine is running. Some federal, state, or local laws
require spark arresters in locations where unarrested
sparks could present a fire hazard.
MUFFLER DEFLECTOR
The POWER-ARC 5500, Honda model, may or may
not be shipped with an exhaust deflector. If you
received one, you can mount it on the gasoline
engine if your needs so require.
The Robin / Subaru and Honda models of the Power-
Arc 5500 come with a spark arrester as standard
equipment. Refer to the engine owner’s manual for
proper maintenance.
To install the deflector, do the following:
• Align the holes on the deflector plate with the holes
on the muffler.
•
Position the deflector so that the opening points either
right, left, or downward, away from the operator.
CAUTION
CAUTION
Never position the deflector upward. Moisture or
debris can enter the engine and damage it. As a
general safety practice, position the deflector to
direct exhaust gases away from the operator’s
face and eyes.
An incorrect additional spark arrester may lead to
damage to the engine or reduce performance.
-----------------------------------------------------------
-----------------------------------------------------------
• Fasten the deflector onto the muffler with the
screws provided.
NOTE:
The deflector reduces generator output

INSTALLATION
Cable Installation
Install the welding cables to your POWER-ARC 5500
as follows. See Figure A.1 for the location of parts.
WARNING
Do not ground the machine to a pipe that carries
explosive or combustible material.
1. The gasoline engine must be OFF to install weld-
ing cables.
When the POWER-ARC 5500 is mounted on a truck
or a trailer, the machine generator
ground stud MUST be securely connect-
ed to the metal frame of the vehicle. See
Figure A.1. The ground stud is marked
with the symbol.
2. Remove the 1/2 - 13 flanged nuts from the output
terminals.
3. Connect the electrode holder and work cables to
the weld output terminals. You can connect either
cable to either terminal, since the POWER-ARC
5500 provides AC weld current.
4. Tighten the flanged nuts securely.
5. Be certain that the metal piece you are welding
(the “work”) is securely connected to the work
clamp and cable.
PLUGS AND HAND-HELD EQUIPMENT
For further protection against electric shock, any
electrical equipment connected to the generator
receptacles must use a three-blade, grounded type
plug or an Underwriter’s Laboratories (UL) approved
double insulation system with a two-blade plug.
6. Check and tighten the connections periodically.
CAUTION
• Loose connections will cause the output termi-
nals to overheat. The terminals may eventually
melt.
Ground fault protection is needed for hand held
equipment.
• Do not cross the welding cables at the output
terminal connection. Keep the cables isolated
and separate from one another.
WARNING
Lincoln Electric offers a welding accessory kit with
the properly specified welding cables. See the
ACCESSORIES section of this manual for more infor-
mation.
Never operate this machine with damaged or
defective cords. All electrical equipment must be
in safe condition.
-----------------------------------------------------------
MACHINE GROUNDING
AUXILIARY POWER RECEPTACLES
Because the POWER-ARC 5500 creates
its own power from its gasoline-engine
The control panel of the POWER-ARC 5500 features
two auxiliary power receptacles:
driven generator, you do not need to
connect the machine frame to an earth
ground. However, for best protection
• A 20 amp, 120 volt duplex (double outlet) recepta-
cle
against electrical shock, connect a heavy gauge wire
from the ground stud located on the bottom center of
the output panel (see Figure A.1) to a suitable earth
ground such as a metal pipe driven into the ground.
• A 20 amp 240 volt simplex (single outlet) recepta-
cle.
See Figure A.1.
Through these receptacles the machine can supply
up to 4,000 rated continuous watts and 5,500 surge
watts of single-phase AC power.

INSTALLATION
PREMISES WIRING
CIRCUIT BREAKERS
The POWER-ARC 5500 three-wire, grounded neutral
generator allows it to be connected to premises
wiring. However, the wiring procedure needed to
meet the National Electrical Code (NEC) regulations
as well as city ordinances and can be confusing. The
connections could vary from a "commonly grounded"
to a "separately derived" system depending on
whether you want the unit to be "hard wired" or tem-
porary to the premises.
Auxiliary power is protected by circuit breaker. When
the machine is operated in high temperature environ-
ments, the breakers may tend to trip at lower loads
than normally.
CAUTION
Never bypass the circuit breakers. Without over-
load protection, the POWER-ARC 5500 could
overheat and/or cause damage to the equipment
being used.
WARNING
Only a licensed, certified, trained electrician
should install the machine to a premises or resi-
dential electrical system. Be certain that:
• The premises is isolated and no feed backing
into the utility system can occur. Certain state
and local laws require the premises to be isolat-
ed before the generator is linked to the premis-
es. Check your state and local requirements.
• A double pole, double throw transfer switch in
conjunction with the properly rated double
throw circuit breaker is connected bbetween the
generator power and the utility meter.
The POWER-ARC 5500 does not have a combined
120/240 volt twist-lock receptacle and cannot be
connected to a premises as described in other
Lincoln literature.
Remember that the POWER-ARC 5500 is intended
only for backup, intermittent use power. Oil level must
be checked after every 5 hours of use. It cannot with-
stand long-term use without proper maintenance.

The POWER-ARC 5500 is a generator/welder designed
for home use and other non-commercial applications.
As a generator it can supply up to 4,000 continuous
watts (or 5,500 surge watts) of 120/240 volt, single-
phase AC power. As a welder it provides 125 amps of
AC constant current for welding with AC stick elec-
trodes. A single dial provides continuous adjustment of
welding output. The machine is lightweight, portable,
and can be lifted by two people.
Read and understand this entire section before oper-
ating your POWER-ARC 5500.
WARNING
Do not attempt to use this equipment until you
have thoroughly read all the operation and main-
tenance manuals supplied with your machine.
They include important safety precautions;
detailed engine starting, operating, and mainte-
nance instructions; and parts lists.

WELDER
The POWER-ARC 5500 provides excellent constant cur-
rent AC welding output for stick (SMAW) welding. For
more details on using the machine as a welder, see
WELDING OPERATION in the OPERATION section of
this manual.
• Use ventilation or exhaust to
remove fumes from breathing zone.
WELDING SPARKS can cause
fire or explosion.
• Keep flammable material away.
OPERATIONAL FEATURES AND
CONTROLS
• Do not weld on containers that have
held combustibles.
The POWER-ARC 5500 was designed for simplicity.
Therefore, it has very few operating controls. A single
dial on the control panel lets you select either generator
or welding use. For welding, the same dial selects con-
tinuous current output over the machine’s 70 to 125
amp range.
ARC RAYS can burn.
• Wear eye, ear, and body protection.
The gasoline engine controls include a recoil starter,
choke, and rotary stop switch. See ENGINE OPERA-
TION in the OPERATION section of this manual and the
engine owner’s manual for details about starting, run-
ning, stopping, and breaking in the gasoline engine.

• Use in open, well ventilated areas or
vent exhaust to the outside.
• Do not stack anything on or near the
engine.
WELDING CAPABILITY
The POWER-ARC 5500 is rated 125 amps, 20 volts at
30% duty cycle on a ten-minute basis. This means
that you can load the welder to 125 amps for three
minutes out of every ten-minute period. The machine
is also capable of higher duty cycles at lower output
currents. You can load the welder to 100 amps for six
minutes out of ten for a 60% duty cycle.
MOVING PARTS can injure.
• Do not operate this equipment with
any of its doors open or guards off.
• Stop the engine before servicing it.
• Keep away from moving parts.
The current is continuously variable from 70 to 125
amps AC. The POWER-ARC 5500 can weld with all
3/32 and most 1/8 inch diameter Lincoln AC elec-
trodes.
Only qualified personnel should install, use, or ser-
vice this equipment.

OPERATION
4. Pull the cord rapidly.
BEFORE STARTING THE ENGINE
CHECK AND FILL THE ENGINE OIL LEVEL:
1. Place the machine on a level
surface.
5. If the engine does not start, open the choke
slightly and pull the starter cord rapidly again.
When the engine starts, gradually open the choke
to the “RUN” position. To open the choke fully
requires an engine warm-up period of several
seconds to several minutes, depending on the
temperature. After starting the engine, first open
the choke (toward RUN) until the engine just
begins to run smoothly. Then open the choke in
small steps, allowing the engine to accept small
changes in speed and load, until the choke is fully
open (in RUN). During engine warm-up the equip-
ment can be operated.
2. Open the oil fill plug.
3. Fill (if necessary) until oil flows out the top of the
fill plug hole.
4. Replace the fill plug and tighten securely.
CHECK AND FILL THE ENGINE FUEL TANK:
1. Remove the fuel tank cap.
2. Fill the tank to allow approximately 1/4
inch (5 mm) of tank space for fuel
expansion. DO NOT FILL THE TANK
TO THE POINT OF OVERFLOW.
FOR A “HOT” ENGINE:
1. Open the fuel shutoff valve.
3. Replace the fuel tank cap and tighten securely.
2. Place the choke lever in the “RUN”
position. Closing the choke of a hot
engine will flood the carburetor and
prevent starting.
NOTE:
The engine will operate satisfactorily on any
gasoline meant for automotive use. A mini-
mum of 87 octane is recommended. DO NOT
MIX OIL WITH THE GASOLINE.
3. Pull slightly on the recoil starter handle until resis-
tance is felt.
Use clean, fresh, lead-free gasoline. Leaded gasoline
may be used if lead-free is not available. However,
lead-free gasoline leaves fewer combustion deposits
and gives longer valve life. Purchase gasoline in
quantities that will be used within 30 days, to assure
freshness.
4. Pull the cord rapidly.
FOR BEST ENGINE STARTING:
• Always use fresh gasoline and be sure the filter is
clean and properly maintained.
NOTE:
We DO NOT recommend using gasoline that
contains alcohol, such as gasohol. However,
if gasoline with alcohol is used, it MUST NOT
contain more than 10% Ethanol and MUST
be removed from the engine during storage.
DO NOT use gasoline containing Methanol.
• If you use an alternate fuel tank or supply, be sure
to install an in-line fuel filter.
• Do not pull the recoil starter with the
choke in the “CHOKE” position more
than one time. Repeated pulls on a
choked engine will flood the carbure-
tor.
STARTING THE ENGINE
NOTE: Remove all loads connected to the AC power
receptacles before starting the gasoline
engine. Put the “ON/OFF” Switch in the
“ON”(I) position.
• If the engine will not start, see the TROU-
BLESHOOTING section of this or the engine
owner’s manual.
FOR A “COLD” ENGINE:
1. Open the fuel shutoff valve.
2. Place the choke lever in the “CHOKE”
position.
3. Pull slightly on the recoil starter handle until resis-
tance is felt.

GENERATOR OPERATION
1. Remove all welding and generator power loads
and let the engine cool by running it for several
minutes.
CAUTION
Be sure that any electrical equipment plugged into
the generator’s AC power receptacles can with-
stand a 10% voltage and a 4% frequency varia-
tion. Some electronic devices cannot be powered
by the POWER-ARC 5500. Refer to TTable A.2,
ELECTRICAL DEVICE USE WITH THE POWER-
ARC 5500, in the INSTALLATION section of this
manual.
2. Stop the engine by placing the “ON/OFF” switch
O
in the “OFF”( ) position.
3. Close the fuel shutoff valve.
WARNING
-----------------------------------------------------------
Close the fuel valve when the machine is trans-
ported to prevent fuel leakage from the carbure-
tor. Drain the tank before transporting the
machine in a vehicle.
GENERAL INFORMATION
The POWER-ARC 5500 generator is rated at 4000
continuous watts (5500 surge watts). It provides both
120 volt and 240 volt power. You can draw up to 20
amps from either side of the 120 volt duplex recepta-
cle, but no more than 33.3 amps from both sides at
once. Up to 16.7 amps can be drawn from the single
240 volt receptacle.
For long periods of storage, turn off the fuel shut-
off valve and let the engine run until there is no
more fuel in the line. Use a fuel additive such as
Sta-Bil to minimize fuel gum deposits.
-----------------------------------------------------------
Electrical loads in watts are calculated by multiplying
the voltage rating of the load by the number of amps
it draws. (This information is given on the load device
nameplate.) For example, a device rated 120 volts, 2
amps will need 240 watts of power (120 x 2 = 240).
RUNNING THE ENGINE
The engine is set at the factory to run at high idle
speed when not under load. You should not adjust
this setting yourself.
You can use Table B.3, GENERATOR POWER APPLI-
CATIONS, to determine the wattage requirements of
the most common types of loads you can power with
the POWER-ARC 5500. Be sure to read the notes at
the bottom of the table.
BREAK-IN PERIOD
The engine will use a greater amount of oil during its
“break-in” period. Check the oil frequently during
break-in. For more details, see the MAINTENANCE
section in the engine owner’s manual.
TO USE THE POWER - ARC 5500 AS AN AUXIL-
IARY POWER SUPPLY:
ENGINE OPERA-
1. Start the gasoline engine. See
TION
owner’s manual.
in this section of the manual and the engine
CAUTION
During break-in, subject the POWER-ARC 5500 to
only moderate loads. Avoid long periods running
at idle. Before stopping the engine, remove all
loads and allow the engine to cool several min-
utes.
2. Set the current control dial on the output control
panel to “GENERATOR.” See Figure B.1.
3. Plug the load(s) into the appropriate 120 volt or
240 volt power receptacle.
NOTE:
During welding, the maximum generator out-
put for auxiliary loads is 100 watts.
-------------------------------------------------------------
NOTE:
You can supply multiple loads as long as the
total load does not exceed 5,500 surge watts
or 4,000 Continuous watts. Be sure to start
the largest loads first.

NOTES:
Wattages listed are approximate. Check your equipment for actual wattage.
Equipment with unusually high *START-UP WATTS are listed. For start-up of other tabled equipment that uses a
motor, allow up to 2 times the running watts shown above. For example a 1 HP motor requires approximately
1000 watts of power when running but may require (2.5 X 1000) = 2500 watts or (4.0 X 1000) = 4000 watts to
start.
Multiple loads can be used as long as the total load does not exceed 5,500 surge watts or 4,000 continuous
watts. Be certain to start the largest loads first.
Output rating in watts is equivalent to volt-amperes at unity power factor (resistive load) and is calculated as:
WATTS = VOLTS X AMPS DRAWN. for example a 120 volt device which is rated on its nameplate to draw 2
amps will need (120 VOLTS) X (2 AMPS) = 240 WATTS OF POWER. 1 KW = 1000 WATTS.

WELDING OPERATION
GENERAL INFORMATION
AFTER YOU FINISH THE WELD:
WARNING
1. Stop the gasoline engine. See ENGINE OPERA-
TION in this section of the manual.
ELECTRIC SHOCK can kill.
• Do not touch electrically live parts or
electrodes with your skin or wet cloth-
ing.
2. Allow the electrode and work to cool completely.
3. Remove the work clamp from the work.
4. Remove any remaining piece of electrode from
the electrode holder.
• Insulate yourself from the work and ground.
• Always wear dry insulating gloves.
5. If you are finished using the POWER-ARC 5500
for welding, disconnect the welding cables from
the weld output terminals. Reattach the flange
nuts and leave them on the terminals.
-----------------------------------------------------------
The POWER-ARC 5500 has a voltage of up to 62
Volts AC which can shock. The POWER-ARC 5500
generator/welder can deliver from 70 to 125 amps of
continuous welding output current. Output can be
adjusted by setting the current control dial on the out-
put control panel.
NOTE: 1. Welding current is continuously variable
with 60% duty cycle applying to output
currents 100 Amps and less and 30%
duty cycle applying to currents above 100
Amps.
You can get maximum welding output by setting the
dial to 125 AMPS. At high current settings like this,
some output may decrease as the machine is used.
If you are welding for a long time, you may need to
turn the dial slightly upward to maintain the same
results.
2. Duty cycle is based on a ten minute
period. The welder can be loaded to 125
Amps for three minutes out of every ten
minute period or to 100 Amps for six
minutes out of every ten minute period.
The numbers on the dial correspond to the average
amps needed to weld using specific Lincoln welding
rods. Table B.4, WELDING APPLICATIONS, gives
you the recommended dial settings based on the
thickness of the work and the size and type of rod
you’re using.
CONTROL FUNCTION / OPERATION
“Current Control Dial”
Provides welding current adjustment from 70 through
125 Amps.
To obtain maximum weld output, turn the “Current
Control Dial” to “125 Amps” for either a cold or hot
engine. As the machine is used, some welding volt-
age may decrease at high current settings. If you are
welding for long periods of time, the dial may need to
be slightly turned upward to provide the same welding
results as when the machine was cold.
TO USE THE POWER-ARC 5500 FOR WELDING:
1. Remove the flange nuts from the weld output ter-
minals and place the work and electrode welding
cables over the terminals. (See Figure B.1)
Replace and tighten the flange nuts securely. Be
sure the connections are tight.
The numbers listed on the dial correspond to the aver-
age amperage needed to weld specific Lincoln rods.
Refer to Table B.4 “Welding Application Guidet” and
“Electrode Selection Guide” listed on the machine
nameplate for proper current and electrode settings.
2. Select the appropriate electrode. (See Table B.4)
WELDING APPLICATIONS, or the ELECTRODE
SELECTION GUIDE on the machine Output
Control Panel.
3. Attach the work clamp securely to the work you
are welding.
4. Insert the electrode into the electrode holder.
5. Set the current control dial to the desired output
current.

Stick Welding
The values listed are suggested settings. Actual set-
ting may vary depending on individual preference
and/or specific application. Beginners should use
Lincoln E7018 AC.
Stick welding is probably the most familiar welding
process known. A coated ELECTRODE, the weld rod,
is clamped into an ELECTRODE HOLDER, an insulat-
ed clamping device, which in turn connects to the
ELECTRODE CABLE, a heavy wire. The WORK, the
metal piece to be welded, is connected to the WORK
CABLE, a heavy wire which contains the WORK
CLAMP. Quality Lincoln cables use many fine copper
wires with a very flexible insulating covering for the
electrode and work cables. When properly connected
to the OUTPUT STUDS of a high current power
source, the electrode melts and bonds the metal being
repaired. See “Cable Installation” section for proper
cable connection to a Power-Arc.
For electrodes not listed, follow tables that are
packed with the electrodes.
Ask for the Lincoln WELD DIRECTORY (Publication
C2.10) for a complete listing of all Lincoln stick elec-
trodes available.

WARNING
ARC RAYS can burn.
• When using an open arc process,
it is necessary to use correct eye,
head and body protection.
The Power-Arc provides excellent weld output charac-
teristics when used in combination with Lincoln AC
electrodes. Other AC electrodes may also be used.
Follow the settings listed in Table B.4 “Welding
Application Guide” and the “Electrode Selection
Guide” found on the nameplate of the machine.

OPERATION
No one can learn to weld simply by reading about it.
Skill comes only with practice. The following pages
will help the inexperienced welder understand welding
and develop his skill. For more detailed information,
order a copy of the book “New Lessons in Arc
Welding.” (See Book Division section at rear of manual).
The electric arc is made between the work and the tip
end of a small metal wire, the electrode, which is
clamped in a holder that is held by the welder. A gap
is made in the welding circuit (see Figure 3) by hold-
ing the tip of the electrode 1/16 - 1/8” (1.6-3.2mm)
away from the work or base metal being welded. The
electric arc is established in this gap and is held and
moved along the joint to be welded, melting the metal
as it is moved.
The operator s knowledge of arc welding must go
beyond the arc itself. He must know how to control the
arc, and this requires a knowledge of the welding cir-
cuit and the equipment that provides the electric cur-
rent used in the arc. Figure 3 is a diagram of the weld-
ing circuit. The circuit begins where the electrode
cable is attached to the welding machine and ends
where the work cable cable is attached to the
machine. Current flows through the electrode cable to
the electrode holder, through the electrode holder to
the electrode and across the arc. On the work side of
the arc, the current flows through base metal to the
work cable and back to the welding machine. The cir-
cuit must be complete for the current to flow. To weld,
the work clamp must be tightly connected to clean
base metal. Remove paint, rust,etc. as necessary to
get a good connection. Connect the work clamp as
close as possible to the area you wish to weld. Avoid
allowing the welding circuit to pass through hinges,
bearings, electronic components or similar devices
that can be damaged.
Arc welding is a manual skill requiring a steady hand,
good physical condition, and good eyesight. The oper-
ator controls the welding arc and, therefore, the quali-
ty of the weld made.
What Happens in the Arc?
Figure 4 illustrates the action that takes place in the
electric arc. It closely resembles what is actually seen
during welding.
The “arc stream” is seen in the middle of the picture.
This is the electric arc created by the electric current
flowing through the space between the end of the
electrode and the work. The temperature of this arc is
about 6000°F (3300°C) which is more than enough to
melt metal. The arc is very bright, as well as hot, and
cannot be looked at with the naked eye without risking
painful and possibly permanent injury. A very dark
lens, specifically designed for arc welding must be
used with the handshield or headshield whenever
viewing the arc.

The arc melts the base metal and actually digs into it,
much like water through a garden hose nozzle digs
into the earth. The molten metal forms a pool or crater
and tends to flow away from the arc As it moves away
from the arc, it cools and solidifies. Slag forms on top
of the weld to protect it during cooling.

OPERATION
The function of the covered electrode is much more
than simply to carry current to the arc. The electrode
is composed of a core metal wire around which has
been extruded and baked a chemical covering. The
core wire melts into the arc and tiny droplets of molten
metal shoot across the arc into the molten pool. The
electrode provides additional filler metal for the joint to
fill the groove or gap between the two pieces of the
base metal. The covering also melts or burns in the
arc. It has several functions. It makes the arc steadier,
provides a shield of smoke-like gas around the arc to
keep oxygen and nitrogen in the air away from the
molten metal, and provides a flux for the molten pool.
The flux picks up impurities and forms a protective
slag. The principle differences between the various
types of electrodes are in their coatings. By varying
the coating, it is possible to greatly alter the operating
characteristics of electrodes. By understanding the dif-
ferences in the various coatings, you will gain a better
understanding of selecting the best electrode for the
job you have at hand. In selecting an electrode, you
should consider:
1. The type of deposit you want, e.g., mild steel,
stainless, low alloy, hardfacing.
2. The thickness of the plate you want to weld.
3. The position it must be welded in (downhand,
out-of-position).
4. The surface condition of the metal to be welded.
5. Your ability to handle and obtain the desired
electrode.
Four simple manipulations are of prime importance.
Without complete mastery of these four, further
attempts at welding are futile. With complete mastery
of the four, welding will be easy.
2. The Correct Way to Strike An Arc
Be sure the work clamp makes good electrical contact
to the work.
Lower your headshield and scratch the electrode
slowly over the metal, and you will see sparks fly.
While scratching, lift the electrode 1/8” (3.2mm) and
the arc is established.
NOTE: If you stop moving the electrode while
scratching, the electrode will stick. Most beginners try
to strike the arc by a fast jabbing motion down on the
plate. Result: They either stick their electrode or their
motion is so fast that they break the arc immediately.
3. The Correct Arc Length
The arc length is the distance from the tip of the
electrode core wire to the base metal.
Once the arc has been established, maintaining the
correct arc length becomes extremely important. The
arc should be short, approximately 1/16 to 1/8” (1.6-
3.2mm) long. As the electrode burns off, the electrode
must be fed to the work to maintain correct arc length.
The easiest way to tell whether the arc has the correct
length is by listening to its sound. A nice, short arc has
a distinctive, “crackling” sound, very much like eggs
frying in a pan. The incorrect, long arc has a hollow,
blowing or hissing sound.
4. The Correct Welding Speed
The important thing to watch while welding is the pud-
dle of molten metal right behind the arc. DO NOT
WATCH THE ARC ITSELF. The appearance of the
puddle and the ridge where the molten puddle solidi-
fies indicates correct welding speed. The ridge should
be approximately 3/8” (9.5mm) behind the electrode.
1. The Correct Welding Position
Illustrated is the correct welding position for
right-handed people. (For left-handed people it is
opposite.)
Whenever possible, weld from left to right (if right-
handed). This enables you to see clearly what you
are doing.

Hold the electrode at a slight angle as shown in
Figure 5.
Most beginners tend to weld too fast, resulting in a
thin, uneven, “wormy” looking bead. They are not
watching the molten metal.

IMPORTANT: It is not generally necessary to weave
the arc forward, backward or sideways. Weld along at
a steady pace, and you will have an easier time.

NOTE: When welding on thin plate, you will find that
you have to increase the welding speed, whereas
when welding on heavy plate, it is necessary to go
more slowly to ensure fusion and penetration.

OPERATION
These higher carbon steels can be welded successful-
ly in most cases; however, care must be taken to fol-
low proper procedures, including preheating the metal
to be welded and, in some cases, carefully controlling
the temperature during and after the welding process.
For further information on identifying various types of
steel and other metals, and for proper procedures for
welding them, we suggest you purchase a copy of
“New Lessons in Arc Welding” (See Book Division
section).
PRACTICE
The best way of getting practice in the four skills that
enable you to maintain:
1. Correct Welding Position.
2. Correct Way to Strike An Arc.
3. Correct Arc Length.
4. Correct Welding Speed.
is to spend a little more time on the following exercise.
Regardless of the type of metal being welded, in order
to get a quality weld, it is important that it be free of
oil, paint, rust or other contaminants.
Use the following:
Mild Steel Plate:
3/16” (4.8mm), or heavier.
Electrode:
1/8” (3.2mm) AWS 6011
(Fleetweld® 180)
Types of Welds
Current Setting:
90-125 Amps AC
Five types of welding joints are: Butt Joints, Fillet
Joints, Lap Joints, Edge Joints and Corner Joints.
Do the following:
1. Learn to strike the arc by scratching the electrode
over the plate. Be sure the angle of the electrode
is right and be sure to use both hands.
Of these, the Butt Joint and Fillet Joint are the most
common.
2. When you can strike an arc without sticking, prac-
tice the correct arc length. Learn to distinguish it
by its sound.
3. When you are sure that you can hold a short,
crackling arc, start moving. Look at the molten
puddle constantly, and look for the ridge where the
metal solidifies.
Butt oint
Lap oint
4. Run beads on a flat plate. Run them parallel to the
top edge (the edge farthest away from you). This
gives you practice in running straight welds, and
also, it gives you an easy way to check your
progress. The 10th weld will look considerably bet-
ter than the first weld. By constantly checking on
your mistakes and your progress, welding will soon
be a routine matter.
Corner oint
Fillet oint
Edge oint
Butt Joints
Butt Joints are the most widely used Joints. Place two
plates side by side, leaving 1/16” (1.6mm) for thin
metal to 1/8” (3.2mm) for heavy metal space between
them in order to get deep penetration.
Common Metals
Most metals found around the farm or small shop are
low carbon steel, sometimes referred to as mild steel.
Typical items made with this type of steel include most
sheet metal, plate, pipe and rolled shapes such as
channels, angle irons and “I” beams. This type of
steel can usually be easily welded without special
precautions. Some steel, however, contains higher
carbon. Typical applications include wear plates,
axles, connecting rods, shafts, plowshares and
scraper blades.
Tack the plates at both ends, otherwise the heat will
cause the plates to move apart. (See drawing).

Now weld the two plates together. Weld from left to
right (if right-handed). Point the electrode down in he
gap between the two plates, keeping the electrodes
slightly tilted in the direction of travel.
Fillet Joints
When welding fillet joints, it is very important to hold
the electrode at a 45° angle between the two sides, or
the metal will not distribute itself evenly.

To make it easier to get the 45° angle, it is best to put

Welding in the Vertical Position
In this example, the joint has been flame beveled or
ground prior to welding so that 100% penetration
could be achieved. The weld, if properly made, is as
strong or stronger than the original metal.
Welding in the vertical position can be done either
vertical-up or vertical-down. Vertical-up is used
whenever a large, strong weld is desired.
Vertical-down is used primarily on sheet metal for fast,
low penetrating welds.

8. When the arc is brought back to the now solidified
puddle, IT MUST BE SHORT, otherwise no metal
will be deposited, the puddle will melt again, and it
will “drip”.
Vertical-Up Welding
The problem, when welding vertical-up, is to put the
molten metal where it is wanted and make it stay
there. If too much molten metal is deposited, gravity
will pull it downwards and make it “drip”. Therefore, a
certain technique has to be followed:
9. It is important to realize that the process consists
of SLOW, DELIBERATE movements. There are no
fast motions.
Long arc
Vertical-Down Welding
Short arc
NOTE: Holder end of electrode
is lower than arc.
Vertical-down welds are applied at a fast pace. These
welds are therefore shallow and narrow, and are
excellent for sheet metal. Do not use the vertical-down
technique on heavy metal. The welds will not be
strong enough.
1. Use 1/8” (3.2mm) 90-115 amps or 3/32” (2.5mm)
70 amps AWS 6011.
2. When welding, the electrode should be kept hori-
zontal or pointing slightly upwards. (See drawing
above).
1. Use 1/8” (3.2m) or 3/32” (2.5mm) AWS 6011.
3. The arc is struck and metal deposited at the bot-
tom of the two pieces to be welded together.
2. On thin metal use 70-75 amps.
(14 ga. 75 A - 16 ga. 60 A.)
4. Before too much molten metal is deposited, the arc
is SLOWLY moved 1/2-3/4” (12-20mm) upwards.
This takes the heat away from the molten puddle,
which solidifies. (If the arc is not taken away soon
enough, too much metal will be deposited, and it
will “drip”.)
3. Hold the electrode in a 30-45° angle with the tip of
the electrode pointing upwards.
4. Hold a VERY SHORT arc, but do not let the elec-
trode touch the metal.
Very
5. The upward motion of the arc is caused by a very
slight wrist motion. Most definitely, the arm must
not move in and out, as this makes the entire
process very complicated and difficult to learn.
5. An up and down whipping
motion will help prevent
short
arc
30°-40°
burn-through on very thin plate.
6. Watch the molten metal carefully.
6. If the upward motion of the arc is done correctly
with a wrist motion, the arc will automatically
become a long arc that deposits little or no metal.
(See drawing above.)
The important thing is to continue lowering the entire
arm as the weld is made so the angle of the electrode
does not change. Move the electrode fast enough so
that the slag does not catch up with the arc.
7. During this entire process, the ONLY thing to
watch is the molten metal. As soon as it has solidi-
fied, the arc is SLOWLY brought back, and another
few drops of metal are deposited. DO NOT FOL-
LOW THE UP AND DOWN MOVEMENT OF THE
ARC WITH YOUR EYES. KEEP THEM ON THE
MOLTEN METAL.

4. Move rapidly enough to stay ahead of the molten
slag. A whipping technique may be used to further
minimize burn through.
Overhead Welding
Various techniques are used for overhead welding.
However, in the interest of simplicity for the inexperi-
enced welder, the following technique will probably
take care of his needs for overhead welding:
5. If you have a choice, use lap joints rather than fil-
lets or butts; the double thickness effect of a lap
joint makes it much easier to weld without burning
through.
1. Use 1/8” (3.2mm) 90-105 A or 3/32” (2.5mm) 70 A
AWS 6011 electrode on AC.
Hardfacing (To Reduce Wear)
2. Put the electrode in he holder so it sticks straight
out.
There are several kinds of wear. The two most often
encountered are:
3. Hold the electrode at an angle approximately 30°
off vertical, both seen from the side and seen from
end. (See drawing below.)
1. Metal to Ground Wear: Plowshares, bulldozer
blades, buckets, cultivator shares, and other metal
parts moving in the soil.
End View
Side View
2. Metal to Metal Wear: Trunnions, shafts, rollers and
idlers, crane and mine car wheels, etc.
30°
30°
Each of these types of wear demands a different kind
of hardfacing electrode.
It is important to hold a VERY SHORT arc. (A long
arc will result in falling molten metal; a short arc will
make the metal stay.)
When applying the proper electrode, the service life of
the part will in most cases be more than double. For
instance, hardfacing of plowshares results in 3-5 times
more acreage plowed.
If necessary, and this is dictated by the appearance of
the molten puddle, a slight back and forth whipping
technique may be used to prevent “dripping”.
How to Hardface the Sharp Edge (Metal to Ground
Wear)
Welding Sheet Metal
1. Grind the share, approximately one inch along the
edge, so the metal is bright and clean.
Welding sheet metal presents an additional problem-
burn through. Follow these simple rules:
2. Place the share on an incline of approximately
20-30°. The easiest way to do this is to put one
end of the share on a brick. (See drawings) Most
users will want to hardface the underside of the
share, but some might find that the wear is on the
top side. The important thing is to hardface the
side that wears.
1. Hold a very short arc. This, together with the prop-
er travel speed, will eliminate burn through.
2. Use 1/8” (3.2mm) or 3/32” (2.5mm) AWS 6011.
3. Use low amperage. 75 A for 1/8” (3.2mm) elec-
trode, 70 A for 3/32” (2.5mm) electrode.
3. Use 1/8” (3.2mm) Wearshield at 80-100 A. Strike
the arc about one inch from the sharp edge.

4. The bead should be put on with a weaving motion,
and it should be 1/2-3/4” (12.7-19.0mm) wide. Do
not let the arc blow over the edge, as that will dull
the edge. (See drawing below.)

1. Preheat the entire casting to 500-1200°F (260-

will be no sudden chilling which creates brittle
white cast iron. The entire casting will cool slowly.

5. Use the back-stepping method. Begin to weld 3”
(76mm) from the heel of the share and weld to the
heel. The second weld will begin 6” (152mm) from
the heel, the third weld 9” (229mm) from the heel,
etc.
2. Weld 1/2” (12.7mm) at a time, and do not weld at
that spot again until the weld is cool.
This way, no large amount of heat is put into the
mass.

Most inexperienced welders will probably use the sec-

large castings. Smaller castings can easily (and
should) be preheated before welding. A forge, stove,
fire, or the Arc Torch are all excellent means of pre-
heating.
BACKSTEPPING
Backstepping greatly reduces the chances for crack-
ing of the share, and it also greatly reduces warping.
When using the 1/2” (12.7mm) at a time method, it is
recommended to start 1/2” (12.7mm) away from the
previous bead and weld into the previous bead. This
is called backstepping.
NOTE: The entire process is rather fast. Many begin-
ners go much too slowly when hardfacing plowshares,
running the risk of burning through the thin metal.
After welding Cast Iron, protect the casting against
fast cooling. Put it in a container of warm, dry sand or
lime.
Welding Cast Iron
When welding on a piece of cold cast iron, the
tremendous heat from the arc will be absorbed and
distributed rapidly into the cold mass. This heating
and sudden cooling creates WHITE, BRITTLE cast
iron in the fusion zone. (See drawing below.)
If sand or lime is not available, cover it with sheet
metal or any other non-flammable material that will
diminish drafts and retain heat.

Cast Iron Plate Preparation

Wherever practical, the joint to be welded should be
“veed” out by grinding or filing to give complete pene-
tration as shown in figures (a), (b) and (c) below. This
is especially important on thick castings where maxi-
mum strength is required.
This is the reason why welds in cast iron break.
Actually, one piece of the broken cast iron has the
entire weld on it and the other piece has no weld on it.

OPERATION
In some instances a back-up strip may be used and
plates may be gapped 1/8” (3.2mm) or more, as
shown in figure (b).
High-Speed Group (AWS E6013)
This group includes electrodes which have a moder-
ately forceful arc and deposit rates between those of
the out-of-position and high-deposit electrodes.
Scrap steel back-up strip
(b)
(c)
(a)
They are primarily general purpose production elec-
trodes especially for downhill fillets and laps or short
and irregular welds that change direction or position.
They are also widely used in maintenance and recom-
mended for sheet metal fillet and lap welds. Motion
“D” (see drawing) is generally used for vertical-up
welding, but motions “A” and “B” are also suitable.
Three ways to prepare plates where
complete penetration is necessary.
On sections where only a sealed joint is required and
strength is not important, the joint may be welded after
slightly veeing out the seam as shown in figure (d)
below.
Low Hydrogen Group (AWS E7018)
(d)
(e)
These electrodes are generally called “low hydrogen”.
The name comes from the fact that their coating
contains little hydrogen in either moisture or chemical
form. Low hydrogen electrodes offer these benefits:
outstanding crack resistance, lowest porosity on
sulphur bearing steels, and X-ray quality deposit capa-
bility. Thus, they are the first choice when welding
“problem” steels. E7018 can be used in all positions,
with Motion “C” (below) recommended for the first
pass on vertical-up welds. NEVER use a whipping
technique or a long arc with these electrodes.
ALWAYS fill craters by drawing electrode away slowly.
ALWAYS keep these electrodes dry. Electrodes, when
not used within a few hours after a container is
opened, must be stored in heated cabinets.
Single and double beads, with and without
beveling for tight, partial strength joints.
Selecting Electrodes
Which electrode is best for the particular job . . . how
do you use it? These are important questions because
the cost, quality, and appearance of your work
depends on proper electrode selection and applica-
tion. MILD STEEL ELECTRODES may be classified
into the following groups:
Out-of-Position Group (AWS E6011)
This group includes electrodes which have a snappy,
deep penetrating arc and fast freezing deposits.
Motions
E
D
These electrodes are used for general purpose, all-
position fabrication and repair welding. They are also
the best choice for pipe welding and sheet metal butt,
corner, and edge welds. They can be used for repair
work when dirt, grease, plating or paint cannot be
completely cleaned from the steel. These electrodes
are typically used with motions “A” and “B” (see draw-
ing) for the first pass on vertical-up welds.

MAINTENANCE
Once Oil or Air filter service is completed,
Tachometer/Hourmeter needs to be reset. The reset
procedure will stop the flashing of the display and will
trigger the meter to start counting the time for the
next engine service. To stop the flashing alert for Oil
or Air filter service, do the following: While alert mes-
sage is flashing, hold the tip of the rest tool against
area shown in figure D.1 for several seconds. The dis-
play will stop flashing. The service interval has been
reset and the message alert should start flashing for
the next Oil or Air filter change.

once a week in particularly dirty areas.
NOTE: Lincoln offers a rotor removal kit for any ser-
vice which requires removal of the rotor from the
engine. See the ACCESSORIES section for further
details.
BRUSH REMOVAL AND REPLACEMENT:
See
Figure D.5. It’s normal for the brushes and slip
rings to wear and darken slightly. Inspect the
brushes when a general overhaul is necessary.
Remove the brushes and clean the slip rings with
fine grit emery paper.
Removal of engine/generator assembly from the
cradle can be achieved as follows:
• Remove the two 5/16-18 hex head cap screws
from the engine block via the access hole located
in the cradle cross support channel. Leave all
other engine mountings intact.
CAUTION
Do not attempt to polish slip rings while engine
is running.
• Remove the two hex nuts from the isolator thread-
ed posts at the stator support bracket located
opposite the engine. Leave all other stator mount-
ings intact.
To reinstall the brushes, press them upward and
slide a cable tie or wooden stick through the brush
holder tabs. Install the brush holder into the bear-
ing end bracket and secure with the screws previ-
ously removed. Remove the cable tie or wooden
stick and the brushes will seat onto the slip rings.
