should conform to ANSI Z87. I standards.
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

• DC Manual (Stick) Welder.
• AC Welder with Reduced Voltage Control.
fumes and gases.When welding, keep
your head out of the fume. Use enough
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.
5.b. 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
products.
3.f. Maintain the electrode holder, work clamp, welding cable and
welding machine in good, safe operating condition. Replace
damaged insulation.
3.g. Never dip the electrode in water for cooling.
5.c. 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.
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.d. 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.
3.i. When working above floor level, use a safety belt to protect
yourself from a fall should you get a shock.

SAFETY
WELDING SPARKS can
cause fire or explosion.
CYLINDER may explode
if damaged.
6.a. Remove fire hazards from the welding area.
If this is not possible, cover them to prevent
7.a. Use only compressed gas cylinders
containing the correct shielding gas for the
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.
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.
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.
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.
•A safe distance from arc welding or cutting operations and
any other source of heat, sparks, or flame.
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
circuits. 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.
6.h. Also see item 1.c.
8.c. Ground the equipment in accordance with the U.S. National

zones où l’on pique le laitier.
PRÉCAUTIONS DE SÛRETÉ
Pour votre propre protection lire et observer toutes les instructions
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 L’Arc
1. Protegez-vous contre la secousse électrique:
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
levage, 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.
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.
c. Maintenir le porte-électrode, la pince de masse, le câble
de soudage et la machine à souder en bon et sûr état
defonctionnement.
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.
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 fortement toxique)
ou autres produits irritants.
d.Ne jamais plonger le porte-électrode dans l’eau pour le
refroidir.
e. Ne jamais toucher simultanément les parties sous tension
des porte-électrodes connectés à deux machines à souder
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 protéger
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 dispositif
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-inflammables.
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.
5. Toujours porter des lunettes de sécurité dans la zone de
soudage. Utiliser des lunettes avec écrans lateraux dans les

Auxiliary Power
GENERAL DESCRIPTION
3.0 kVA of nominal 115/230V, 60 Hz, AC1. (See
Optional Features for Power Plug Kits).
The 350-SA is a heavy duty engine-driven DC arc
welding power source capable of providing constant
current output for stick welding or DC TIG welding.
With the addition of the optional Wire Feed Module for
K1314-4, the 350-SA will provide constant voltage
output for running the LN-25, LN-23P or LN-7 wire
feeders. The Wire Feed Module is factory-installed on
the K1314-5 350-SA.
(1)
Output voltage is within 10% at all loads up to
rated capacity.
Welder Enclosures
The complete welder is rubber mounted on a rugged
steel base.
The output rating of the 350-SA is 350 amperes at 34*
arc volts at 25% duty cycle. Duty cycle is based on a
ten minute period; thus, the welder can be loaded at
rated output for 2.5 minutes out of every ten minute
period.
The output terminals are placed at the side of the
machine so that they are protected by the door. The
output terminals are labeled (+) and (-).
* The output rating at 60% duty cycle is
250 amps at 40V.
Remote Control
K924-1 (for K1314-4, -5 only) - (Field Installed).
Provides a receptacle switch and remote control box
with 100 ft cord for fine current and OCV adjustment
at the welding site.
DESIGN SUMMARY
Control Panel
Cranking System
Both the engine and the welder controls are located
on one recessed panel at the exciter end of the
machine. The welder controls consist of a five step
“Current Range Selector” switch and a “Fine Current
Adjustment” rheostat. Each welder is equipped with a
“Start” button and an “Idler Control” switch. The
Perkins diesel uses a “Thermostart” button, and has a
“Stop” control.
A 12 volt electric starter is standard.
Air Cleaner
Heavy duty two stage dry type.
On this panel is also mounted an engine temperature
gauge, a battery charging ammeter, an oil pressure
gauge, and the three prong grounded type auxiliary
power receptacle.
Muffler
A muffler to reduce engine noise is standard on the
diesel engine units.
Copper Shunt Windings
Engine Hour Meter
For long life and dependable operation.
A meter to record the hours of operation.
Engine Idler
Diesel Engine Protection
The 350-SA is equipped with an electric automatic
engine idler. It automatically increases and decreases
engine speed when starting and stopping welder or
using auxiliary power. A built-in time delay permits
changing electrodes before the engine slows to its low
idle speed. The “Idler Control Switch” on the panel
locks the idler in full speed position when desired.
The system shuts the engine down in the event of
sudden low oil pressure or high coolant temperature.

Machine Grounding
PRE-OPERATION INSTALLATION
Safety Precautions
According to the United States National Electrical
Code, the frame of this portable generator is not
required to be grounded and is permitted to serve as
the grounding means for cord connected equipment
plugged into its receptacle.
WARNING
Do not attempt to use this equipment until you
have thoroughly read the engine manufacturer’s
manual supplied with your welder. It includes
important safety precautions, detailed engine
starting, operating and maintenance instructions,
and parts lists.
Some state, local or other codes or unusual operating
circumstances may require the machine frame to be
grounded. It is recommended that you determine the
extent to which such requirements may apply to your
particular situation and follow them explicitly. A
machine grounding stud marked with the symbol
is provided on the welding generator frame foot. (If an
older portable welder does not have a grounding stud,
connect the ground wire to an unpainted frame screw
or bolt.
------------------------------------------------------------------------
ELECTRIC SHOCK can kill.
• Do not touch electrically live parts or
electrode with skin or wet clothing.
• Insulate yourself from work and
ground
• Always wear dry insulating gloves.
------------------------------------------------------------------------
ENGINE EXHAUST can kill.
• Use in open, well ventilated areas or
vent exhaust outside.
In general, if the machine is to be grounded, it should
be connected with a #8 or larger copper wire to a solid
earth ground such as metal water pipe going into the
ground for at least ten feet and having no insulated
joints, or to the metal framework of a building which
has been effectively grounded. The U.S. National
Electrical Code lists a number of alternate means of
grounding electrical equipment.
------------------------------------------------------------------------
MOVING PARTS can injure.
• Do not operate with doors open or
guards off.
• Stop engine before servicing.
• Keep away from moving parts.
------------------------------------------------------------------------
Lift Bail
See additional warning information at
front of this operator’s manual.
A lift bail is provided for lifting with a hoist.
-----------------------------------------------------------
WARNING
Exhaust Spark Arrester
FALLING EQUIPMENT can cause
injury.
Some federal, state or local laws may require that
diesel engines be equipped with exhaust spark
arresters when they are operated in certain locations
where unarrested sparks may present a fire hazard.
The standard mufflers included with these welders do
not qualify as a spark arrester. When required by
local regulations, suitable spark arresters must be
installed and properly maintained.
• Do not lift this machine using lift bail if
it is equipped with a heavy accessory
such as a trailer or gas cylinder.
• Lift only with equipment of adequate lifting capacity.
• Be sure machine is stable when lifting.
----------------------------------------------------------------------
CAUTION
Trailers (See Optional Features)
Use of an incorrect arrester may lead to engine damage
or performance loss. Contact the engine manufacturer
for specific recommendations.
If the user adapts a non-Lincoln trailer, he must
assume responsibility that the method of attachment
and usage does not result in a safety hazard nor
damage the welding equipment. Some of the factors
to be considered are as follows:
-----------------------------------------------------------------------
Location / Ventilation
Always operate the welder with the doors closed.
Leaving the doors open changes the designed air flow
and may cause overheating.
1. Design capacity of trailer vs. weight of Lincoln
equipment and likely additional attachments.
2. Proper support of, and attachment to, the base of
the welding equipment so there will be no undue
stress to the framework.
The welder should be located to provide an
unrestricted flow of clean, cool air. Also, locate the
welder so that the engine exhaust fumes are properly
vented to an outside area.

3. Proper placement of the equipment on the
undercarriage to ensure stability side to side and
front to back when being moved and when
standing by itself while being operated or serviced.
4. Typical conditions of use, i.e. travel speed,
roughness of surface on which the trailer will be
operated, environmental conditions & likely
maintenance.

5. Conformance with federal, state and local laws.
(1)
Consult applicable federal, state and local laws regarding specific
requirements for use on public highways.
Polarity Control & Cable Sizes
With the engine off, connect the electrode and work
cables of the appropriate size (see the following table)
to the studs located on the fuel tank mounting rail.
For Positive polarity, connect the electrode cable to
the terminal marked “Positive”. For Negative
polarity, connect the electrode cable to the “Negative”
stud. These connections should be checked
periodically and tightened if necessary.
When welding at a considerable distance from the
welder, be sure you use ample size welding cables.

• Wipe up spilled fuel and allow fumes to clear
before starting engine.
To prevent EXPLOSION when:
a) Installing a new battery - disconnect the
negative cable from the old battery first and
connect the negative cable to the new battery
last.
------------------------------------------------------------------------
b) Connecting a battery charger - remove the
battery from the welder by disconnecting the
negative cable first, then the positive cable and
battery clamp. When reinstalling, connect the
negative cable last.
c) Using a booster - connect the positive lead to
the battery first, then connect the negative lead to
the ground lead on the base.
Oil
This unit is supplied from the factory with the engine
crankcase filled with a high quality 10W30 oil. This oil
should be acceptable for most typical ambient
temperatures. Consult the engine operation manual
for specific engine manufacturer’s recommendations.
Upon receipt of the welder, check the engine dipstick
to be sure the oil is at the “full” mark. DO NOT
OVERFILL.
To prevent ELECTRICAL DAMAGE when:
a) Installing a new battery.
b) Using a booster.
Use correct polarity - Negative Ground.
Fuel
To prevent BATTERY DISCHARGE, if you have an
ignition switch, turn it off when engine is not
running.
Fill the fuel tank with the grade of fuel recommended
in the Engine Operator’s Manual. Make sure the fuel
valve on the sediment bowl is in the open position.
• To prevent BATTERY BUCKLING, tighten nuts on
battery clamp until snug.
------------------------------------------------------------------------
Cooling System
The 350-SA is equipped with a wet charged battery.
The charging current is automatically regulated when
the battery is low (after starting the engine) to a trickle
current when the battery is fully charged.
The cooling system has been filled at the factory with
a 50-50 mixture of ethylene glycol antifreeze and
water. Check the radiator level and add a 50-50
solution as needed. (See engine manual or antifreeze
container from alternate antifreeze recommendation.)
When replacing, jumping or otherwise connecting the
battery to the battery cables, the proper polarity must
be observed. The system is NEGATIVE GROUND.

Cold Weather Starting -- When overnight
temperatures are between -12°C (10°F) and freezing,
use the standard “Thermostart” starting system
installed on all engines. Follow the instructions on the
nameplate and in the engine manual shipped with the
welder. With fully charged batteries and the proper
weight oil, the “Thermostart” system operates
satisfactorily even down to about -18°C (0°F).
ENGINE OPERATION
WARNING
Do not attempt to use this equipment until you
have thoroughly read the engine manufacturer’s
manual supplied with your welder. It includes
important safety precautions, detailed engine
starting, operating and maintenance instructions,
and parts lists.
------------------------------------------------------------------------
ELECTRIC SHOCK can kill.
If the engine must be frequently started below -12°C
(10°F), it may be desirable to remove the
“Thermostart” and install the optional ether starter kit.
Installation and operating instructions are included in
the kit. Use ether starting only when required
because excessive use shortens engine life.
• Do not touch electrically live parts or
electrode with skin or wet clothing.
• Insulate yourself from work and
ground
• Always wear dry insulating gloves.
------------------------------------------------------------------------
ENGINE EXHAUST can kill.
• Use in open, well ventilated areas or
vent exhaust outside.
------------------------------------------------------------------------
MOVING PARTS can injure.
• Do not operate with doors open or
guards off.
• Stop engine before servicing.
Stopping the Perkins D3.152 Engine
• Keep away from moving parts.
------------------------------------------------------------------------
a) Turn the ignition control to “OFF”.
See additional warning information at
front of this operator’s manual.
At the end of each day’s welding, refill the fuel tank to
minimize moisture condensation in the tank. Also,
running out of fuel tends to draw dirt into the fuel
system.
-----------------------------------------------------------
Operate the welder with the doors closed. Leaving
the doors open changes the designed air flow and can
cause overheating.
Check the crankcase oil and radiator water level.
Starting the Perkins D3.152 Engine
a) Turn the idler control to “HIGH”.
b) Turn the ignition control to “ON”.
c) Push in the “RESET” button.
d) Press the “START” button. Release button when
engine starts.
e) If the engine fails to start in 60 seconds, wait 30
seconds before repeating the above procedure.
f) Allow the engine to run at high idle speed for
several minutes to warm up. Cold engines tend to
run at a speed too slow to supply the voltage
required for proper idler operation.

When a forceful “digging” arc is required, usually for
vertical and overhead welding, use a higher “Current
Range Selector” setting and lower open circuit
voltage. For example: to obtain 175 amps and a
forceful arc, set the “Current Range Selector” to the
240-160 position and the “Fine Current Adjustment”
setting to get 175 amps.
WELDER OPERATION
WARNING
ELECTRIC SHOCK can kill.
• Do not touch electrically live parts or
electrode with skin or wet clothing.
• Insulate yourself from work and ground.
CAUTION
FUMES & GASES can be dangerous.
• Keep your head out of the fumes.
• Use ventilation or exhaust to remove
fumes from breathing zone.
DO NOT attempt to set the “Current Range Selector”
between the five points designated on the nameplate.
------------------------------------------------------------------------
These switches have a spring loaded cam which
almost eliminates the possibility of setting this switch
between the designated points.
WELDING SPARKS can cause fire or
explosion.
• Keep flammable material away.
ARC RAYS can burn.
• Wear eye, ear, and body protection.
Idler Operation
Start the engine with the “Idler Control” switch in
“High Idle” position. Allow it to run at high idle speed
for several minutes to warm the engine. The
operating speeds are as follows:

The NEMA output rating of the 350-SA is 250
amperes at 30(1) arc volts on a 60% duty cycle. Duty
cycle is based on a ten minute period; thus, the
welder can be loaded at rated output for six minutes
out of every ten minute period.

The idler is controlled by an “Idler Control” toggle
switch on the welder control panel. The switch has
two positions as follows:
(1)
The Lincoln ‘plus output” rating at 60% duty cycle
is 250 amperes at 40 volts.
Control of Welding Current
CAUTION
1. In the “High”
position, the idler is off, and the
engine runs at the high speed controlled by the
governor.
DO NOT TURN THE “CURRENT RANGE
SELECTOR” WHILE WELDING because the
current may arc between the contacts and damage
the switch.
------------------------------------------------------------------------
The “Current Range Selector” provides five
overlapping current ranges. The “Fine Current
Adjustment” adjusts the current from minimum to
maximum within each range. Open circuit voltage is
also controlled by the “Fine Current Adjustment”
permitting control of the arc characteristics.
2. In the “Automatic”
/
position, the
idler operates as follows:
a. When welding or drawing power for lights or
tools (approximately 100-150 watts minimum)
from the receptacles, the engine operates at full
speed.
b. When welding ceases or the power load is
turned off, a preset time delay of about 15
seconds starts. This time delay cannot be
adjusted.
A high open circuit voltage setting provides the soft
“buttering” arc with best resistance to pop-outs
preferred for most welding. To get this characteristic,
set the “Current Range Selector” to the lowest setting
that still provides the current you need and set the
c. If the welding or power load is not re-started
before the end of the time delay, the idler
reduces the engine to low idle speed.
“Fine Current Adjustment” near maximum. For example:
to obtain 175 amps and a soft arc, set the “Current
Range Selector” to the 190-120 position and then adjust
the “Fine Current Adjustment” for 175 amps.

Auxiliary Power
MAINTENANCE
WARNING
The AC auxiliary power, supplied as a standard, has a
rating of 3.0 kVA of 115/230V AC (60 Hz).
Have qualified personnel do the maintenance
work. Turn the engine off before working inside
the machine. In some cases, it may be
necessary to remove safety guards to perform
required maintenance. Remove guards only
when necessary and replace them when the
maintenance requiring their removal is
complete. Always use the greatest care when
working near moving parts.
With the 3.0 kVA, 115/230V AC auxiliary power, one
duplex 115V grounding type receptacle (NEMA
configuration 5-15R) is provided. For the 230V AC
power, one grounding type duplex receptacle is
provided (NEMA configuration 6-15R). The circuit is
protected with circuit breakers.
The rating of 3.0 kVA permits a maximum continuous
current of 13 amps to be drawn from the 230 volt
duplex receptacle. Or a total of 26 amps can be
drawn from the 115 volt duplex receptacle. The 115
volt duplex receptacle has a configuration which
permits 15 amps to be drawn from either half.
Therefore, on this machine, up to 15 amps continuous
can be drawn from one half and the balance of 11
amps from the other half. The total combined load of
all receptacles is not to exceed 3.0 kVA.
Do not put your hands near the engine cooling
blower fan. If a problem cannot be corrected by
following the instructions, take the machine to
the nearest Lincoln Field Service Shop.
-----------------------------------------------------------------------
ELECTRIC SHOCK can kill.
• Do not touch electrically live parts or
electrode with skin or wet clothing.
• Insulate yourself from work and
ground
• Always wear dry insulating gloves.
------------------------------------------------------------------------
ENGINE EXHAUST can kill.
An optional power plug kit is available. When this kit
is specified, the customer is supplied with a plug for
each receptacle. In this case, he will receive two 15
amp, 115 volt plugs (NEMA configuration 5-15P) and
two 15 amp, 230 volt plugs (NEMA configuration
6-15P).
• Use in open, well ventilated areas or
vent exhaust outside.
------------------------------------------------------------------------
MOVING PARTS can injure.
• Do not operate with doors open or

General Instructions for Diesel Engine
Welders
1. Blow out the welder and controls with an air hose
at least once every two months. In particularly
dirty locations, this cleaning may be necessary
once a week. Use low pressure air to avoid driving
dirt into the insulation.
2. “Current Range Selector” contacts should not be
greased. To keep the contacts clean, rotate the
current control through its entire range frequently.
Good practice is to turn the handle from maximum
to minimum setting twice each morning before
starting to weld.
– 15 –
Download from Www.Somanuals.com. All Manuals Search And Download.
3. Change the crankcase oil at regular intervals using
the proper grade of oil as recommended in the
engine operating manual.
When greasing the bearings, keep all dirt out of the
area. Wipe the fittings completely clean and use
clean equipment. More bearing failures are caused
by dirt introduced during greasing than from
insufficient grease.
4. Change the oil filter in accordance with the
instructions in the engine operator’s manual.
When the filter is changed, add a quart of oil to the
crankcase to replace the oil held in the filter during
operation.
Commutator & Brushes
WARNING
5. Inspect the air filter daily - more often in dusty
conditions. When necessary, clean or replace.
The filter should never be removed while the
engine is running.
Uncovered rotating equipment can be dangerous.
Use care so your hands, hair, clothing or tools do
not catch in the rotating parts. Protect yourself
from particles that may be thrown out by the
rotating armature when stoning the commutator.
------------------------------------------------------------------------
The generator brushes are properly adjusted when
the welder is shipped. They require no particular
attention. DO NOT SHIFT THE BRUSHES or adjust
the rocker setting.
6. Change the diesel fuel filters every 500 hours of
operation.
7. Fan belts tend to loosen after the first 30 or 40
hours of operation. Check and tighten if
necessary. DO NOT OVERTIGHTEN.
8. Put a drop of oil on the “Current Range Selector”
shaft at least once every month.
Periodically inspect the commutator, slip rings and
brushes by removing the covers. DO NOT remove or
replace these covers while the machine is running.
9. See the engine manufacturer’s Operating Manual
for detailed engine maintenance and
troubleshooting instructions.
Commutators and slip rings require little attention.
However, if they are black or appear uneven, have
them cleaned by an experienced maintenance man
using fine sandpaper or a commutator stone. Never
use emery cloth or paper for this purpose.
Cooling System
Note: If the welder is used in dirty or dusty locations,
or if the welder is not used for prolonged periods of
time, it may be necessary to clean the commutator
and slip rings more often.
The 350-SA is equipped with a pressure radiator.
Keep the radiator cap tight to prevent loss of coolant.
Clean and flush the cooling system periodically to
prevent clogging the passage and overheating the
engine. When antifreeze is needed, always use the
permanent type.
Replace brushes when they wear within 1/4” of the
pigtail. A complete set of replacement brushes should
be kept on hand. Lincoln brushes have a curved face
to fit the commutator. Have an experienced
maintenance man seat these brushes by lightly
stoning the commutator as the armature rotates at full
speed until contact is made across the full face of the
brushes. After stoning, blow out the dust with low
pressure air.
ORDERING
INFORMATION
COOLING SYSTEM
CAPACITY
K1314-ALL
10 Quarts
To seat the slip ring brushes, position the brushes in
place. Then slide one end of a piece of fine
sandpaper between slip rings and brushes with the
coarse side against the brushes. With slight
additional finger pressure on top of the brushes, pull
the sandpaper around the circumference of the rings,
in direction of rotation only - until brushes seat
properly. In addition, stone slip ring with a fine stone.
Brushes must be seated 100%.
Bearings
This welder is equipped with a double-shielded ball
bearing having sufficient grease to last indefinitely
under normal service. Where the welder is used
constantly or in excessively dirty locations, it may be
necessary to add one-half ounce of grease per year.
A pad of grease one inch wide, one inch long, and
one inch high weighs approximately one-half ounce.
Over-greasing is far worse than insufficient greasing.
Arcing or excessive exciter brush wear indicates a
possible misaligned shaft. Have an authorized Field
Service Shop check and realign the shaft.

Idler Maintenance
TROUBLESHOOTING
WARNING
CAUTION
Before doing electrical work on the idler printed
circuit board, disconnect the battery.
Have qualified personnel do the troubleshooting
work. Turn the engine off before working inside
the machine. In some cases, it may be
necessary to remove safety guards to perform
required maintenance. Remove guards only
when necessary and replace them when the
maintenance requiring their removal is
complete. Always use the greatest care when
working near moving parts.
------------------------------------------------------------------------
1. The solenoid plunger must work freely because
binding can cause engine surging. If surging
occurs, be sure the plunger is properly lined up
with the throttle lever. Dust the plunger about once
a year with graphite powder.
2. When any service is done, reassemble the rubber
bellows on the solenoid plunger with the vent hole
on the lower side.
Do not put your hands near the engine cooling
blower fan. If a problem cannot be corrected by
following the instructions, take the machine to
the nearest Lincoln Field Service Shop.
------------------------------------------------------------

3. Proper operation of the idler requires good
grounding of the printed circuit board (through its
mounting), reed switch and battery.
• Do not touch electrically live parts or
electrode with skin or wet clothing.
• Insulate yourself from work and
ground
4. If desired, the welder can be used without
automatic idling by setting the “Idler Control” switch
to the “High Idle” position.
• Always wear dry insulating gloves.
------------------------------------------------------------------------
ENGINE EXHAUST can kill.
5. When installing a new battery or using a jumper
battery to start the engine, be sure the battery
polarity is connected properly. The correct polarity
is negative ground. Damage to the engine
