open arc welding. Headshield and filter lens  
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.  
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 within applicable OShA PEL and  
ACGIh TLV limits using local exhaust or mechanical  
ventilation. In confined spaces or in some circum-  
stances, 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.

SAFETY  
WELDING and CuTTING  
SPARKS can  
cause fire or explosion.  
CYLINDER may explode  
if damaged.  
7.a. Use only compressed gas cylinders  
containing the correct shielding gas for the  
process used and properly operating  
6.a. Remove fire hazards from the welding area.  
If this is not possible, cover them to prevent  
the welding sparks from starting a fire.  
regulators designed for the gas and  
pressure used. All hoses, fittings, etc. should be suitable for  
the application and maintained in good condition.  
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  
Electrical Code and the manufacturer’s recommendations.  
6.h. Also see item 1.c.  
6.I. Read and follow NFPA 51B “ Standard for Fire Prevention  
During Welding, Cutting and Other Hot Work”, available  
from NFPA, 1 Batterymarch Park, PO box 9101, Quincy, Ma  
022690-9101.  
6.j. Do not use a welding power source for pipe thawing.

SAFETY  
5. Toujours porter des lunettes de sécurité dans la zone de  
PRÉCAuTIONS DE SÛRETÉ  
soudage. Utiliser des lunettes avec écrans lateraux dans les  
zones où l’on pique le laitier.  
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 suiv-  
antes:  
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:  
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.  
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.  
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.  
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 fortement toxique)  
ou autres produits irritants.  
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.

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 ray-  
onnement de l’arc et des projections quand on soude ou  
quand on regarde 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.  
b. Porter des vêtements convenables afin de protéger la  
peau de soudeur et des aides contre le rayonnement de  
l‘arc.  
c. Protéger l’autre personnel travaillant à proximité au  
soudage à l’aide d’écrans appropriés et non-inflammables.  
2. Autant que possible, I’installation et l’entretien du poste seront  
effectués par un électricien qualifié.  
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, pan-  
talons sans revers, et chaussures montantes.  
3. Avant de faires des travaux à l’interieur de poste, la debranch-  
er à l’interrupteur à la boite de fusibles.  
4. Garder tous les couvercles et dispositifs de sûreté à leur  
place.

GENERAL DESCRIPTION  
The “Idler” control switch on the panel locks the idler in high  
idle position when desired.  
The Classic® 300D Perkins is a heavy duty, engine driven,  
DC arc welding power source, capable of providing constant  
current output for stick welding or DC TIG welding. This  
welder is wound with all copper coils, rated at 300 amps/32  
Volts, and provides other Classic® features such as  
improved door latches and stainless hinges. With the addi-  
Auxiliary Power - 3.0 KVA of nominal 115/230V, 60Hz, AC.  
Output voltage is maintained within ± 10% at all loads up to  
rated capacity. (See Optional Features Section C for Power  
Plug Kit.)  
™
tion of the optional K623-1 Wire Feed Module , the  
Classic® 300D Perkins will provide constant voltage output  
for running the LN-7, LN-23P, or LN-25 wire feeders. (The  
Wire Feed Module is factory installed on the K1643-8). The  
optional K924-5 Remote Control Kit, provides a remote con-  
trol rheostat for remote fine current and open circuit voltage  
adjustment. See Section C for description.  
GFCI Module - Protects the 20 amp, 120V duplex recepta-  
cle. See the Maintenance Section for detailed information  
on testing and resetting of the GFCI Module.  
120 V DuPLEx RECEPTACLE AND GFCI MODuLE  
A GFCI Module protects the 120V auxiliary power  
receptacle.  
The Classic® 300D Perkins has an Electronic Engine  
Protection System. In the event of sudden low oil pressure  
or high coolant temperature, the engine immediately shuts  
down. The Classic® 300D Perkins has a current range of  
40-350 DC amps with output ratings as follows:  
A GFCI (Ground Fault Circuit Interrupter) is a device to protect  
against electric shock should a piece of defective equipment  
connected to it develop a ground fault. If this situation should  
occur, the GFCI module will trip, removing voltage from the out-  
put of the receptacle. If a GFCI module is tripped see the  
MAINTENANCE section for detailed information on testing and  
resetting it. A GFCI module should be properly tested at least  
once every month.  
These units are also capable of providing 3 KVA of 115/230  
volts of 60 cycle AC auxiliary power.  
The Classic® 300D Perkins uses the Perkins 404D-22  
industrial water-cooled diesel engine.  
The 120 V auxiliary power receptacle should only be used with  
three wire grounded type plugs or approved double insulated  
tools with two wire plugs. The current rating of any plug used  
with the system must be at least equal to the current capacity of  
the associated receptacle.

TRAILER (SEE OPTIONAL FEATuRES)  
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 weld-  
ing equipment. Some of the factors to be considered are  
as follows:  
Always operate the welder with the doors closed.  
Leaving the doors open changes the designed air flow  
and may cause overheating.  
The welder should be located to provide an unrestrict-  
ed flow of clean, cool air. Also, locate the welder so  
that engine exhaust fumes are properly vented to an  
outside area.

STOPPING ThE ENGINE  
1. Turn the “IGNITION” switch to “OFF”  
STARTING ThE CLASSIC® 300D PERKINS  
404D-22 DIESEL ENGINE  
At the end of each day’s welding, check the crankcase  
oil level, drain accumulated dirt and water from the  
water separator located on the fuel rail. Refill the fuel  
tank to minimize moisture condensation in the tank.  
Also, running out of fuel tends to draw dirt into the fuel  
system.  
1. Turn the “IDLER” switch to “HIGH”.  
2. Turn the “IGNITION” switch to “ON”.  
3. Press the Glow Plug button for 20 to 30 seconds.  
(maximum 60 seconds).  
4. Press the Start button. When the engine starts  
running, release both buttons. If the engine fails to  
start in 20 seconds, wait 30 seconds and repeat  
the above procedure.  
When hauling the welder between job sites, close the  
fuel feed valve on the separator located on the fuel  
rail.  
5. Observe the oil pressure. If no pressure shows  
within 30 seconds, stop the engine and consult  
the engine operating manual. To stop the engine,  
turn the “IGNITION” switch to “OFF”.  
6. If the engine protection warning light comes on  
during cranking or after start up, the “IGNITION”  
switch must be turned “OFF” to reset the engine  
protection system.  
If the fuel supply is cut off or runs out while the fuel  
pump is operating, air may be entrapped in the fuel  
distribution system. If this happens, bleeding of the  
fuel system may be necessary. Use qualified person-

OPERATION  
DuTY CYCLE  
ENGINE bREAK-IN  
The NEMA output rating of the Classic® 300D Perkins is  
300 amperes at 32 arc volts on a 60% duty cycle (consult  
Specifications in this manual for alternate ratings). 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.  
Lincoln Electric selects high quality, heavy-duty industrial  
engines for the portable welding machines we offer.  
While it is normal to see a small amount of crankcase oil  
consumption during initial operation, excessive oil use,  
wet stacking (oil or tar like substance at the exhaust  
port), or excessive smoke is not normal.  
CONTROL OF WELDING CuRRENT  
Larger machines with a capacity of 350 amperes and  
higher, which are operated at low or no-load conditions  
for extended periods of time are especially susceptible to  
the conditions described above. To accomplish success-  
ful engine break-in, most diesel-powered equipment  
needs only to be run at a reasonably heavy load within  
the rating of the welder for some period of time during  
the engine’s early life. However, if the welder is subject-  
ed to extensive light loading, occasional moderate to  
heavy loading of the engine may sometimes be neces-  
sary. Caution must be observed in correctly loading a  
diesel/generator unit.  
CAuTION  
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 cur-  
rent ranges. The “Fine Current Adjustment” adjusts the cur-  
rent from minimum to maximum within each range. Open  
circuit voltage is also controlled by the “Fine Current  
Adjustment” permitting control of the arc characteristics.  
1. Connect the welder output studs to a suitable resis-  
tive load bank. Note that any attempt to short the  
output studs by connecting the welding leads togeth-  
er, direct shorting of the output studs, or connecting  
the output leads to a length of steel will result in cat-  
astrophic damage to the generator and voids the  
warranty.  
A high open circuit voltage setting provides the soft “butter-  
ing” 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 “Fine Current Adjustment” near maxi-  
mum.  
2. Set the welder controls for an output current and  
voltage within the welder rating and duty cycle. Note  
that any attempt to exceed the welder rating or duty  
cycle for any period of time will result in catastrophic  
damage to the generator and voids the warranty.  
3. Periodically shut off the engine and check the  
crankcase oil level.  
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.  
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.  
WELDER OPERATION  
WARNING  
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.  
ELECTRICꢀShOCK can kill.  
• Do not touch electrically live parts or  
electrode with skin or wet clothing.  
Some arc instability may be experienced with EXX10 elec-  
trodes when trying to operate with long arc techniques at  
settings at the lower end of the open circuit voltage range.  
• Insulate yourself from work and ground.

OPERATION  
IDLER OPERATION  
AuxILIARY POWER  
Start the engine with the “Idler” switch in the “High”  
position. Allow it to run at high idle speed for several  
minutes to warm the engine. See Specifications for  
operating speeds.  
If a GFCI Module is tripped, See the MAINTENANCE  
section for detailed information on testing and reset-  
ting the GFCI Module.  
The AC auxiliary power, supplied as a standard, has a  
rating of 3.0 KVA of 115/230 VAC (60 hertz).  
The idler is controlled by the “Idler” toggle switch on  
the welder control panel. The switch has two posi-  
tions as follows:  
With the 3.0 KVA, 115/230 VAC auxiliary power, one  
120V duplex protected by GFCI module and one 230V  
duplex, grounding type receptacle with 2 pole, 15 amp  
circuit breaker.  
1. In the “High”  
position, the idler solenoid  
deactivates, and the engine goes to high idle  
speed. The speed is controlled by the governor.  
The rating of 3.0 KVA permits a maximum continuous  
current of 13 amps to be drawn from the 230 volt  
duplex receptacle. 15 amps can be drawn from the  
120 volt duplex receptacle. The total combined load of  
all receptacles is not to exceed 3.0 KVA.  
2. In the “Auto”  
ates as follows:  
/
position, the idler oper-  
a. When welding or drawing power for lights or tools  
(approximately 100 watts minimum) from the  
receptacles, the idler solenoid deactivates and  
the engine operates at high idle speed.  
An optional power plug kit is available. When this kit is  
specified, the customer is supplied with a plug for  
each receptacle.  
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.  
c. If the welding or power load is not re-started  
before the end of the time delay, the idler sole-  
noid activates and reduces the engine to low idle  
speed.

maintenance requiring their removal is com-  
plete. Always use the greatest care when work-  
ing near moving parts.  
COOLING SYSTEM  
The Classic® 300D Perkins is equipped with a pres-  
sure radiator. Keep the radiator cap tight to prevent  
loss of coolant. Clean and flush the cooling system  
periodically to prevent clogging the passage and over-  
heating the engine. When antifreeze is needed,  
always use the permanent type.  
bEARINGS  
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.  
This welder is equipped with a double-shielded ball  
bearing having sufficient grease to last indefinitely  
under normal service. Where the welder is used con-  
stantly or in excessively dirty locations, it may be nec-  
essary 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.  
• Do not touch electrically live parts or  
electrode with skin or wet clothing.  
• Insulate yourself from work and  
ground  
• Always wear dry insulating gloves.  
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.  
------------------------------------------------------------------------  
ENGINEꢀExhAuSTꢀcan kill.  
• use in open, well ventilated areas or  
vent exhaust outside.  
COMMuTATOR AND bRuShES  
------------------------------------------------------------------------  
MOVING PARTSꢀcan injure.  
WARNING  
• Do not operate with doors open or  
guards off.  
• Stop engine before servicing.  
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 rotat-  
ing armature when stoning the commutator.  
------------------------------------------------------------------------  
Shifting of the commutator brushes may result in:  
- Change in machine output  
- Commutator damage  
• Keep away from moving parts.  
------------------------------------------------------------------------  
See additional warning information at  
front of this operator’s manual.  
-----------------------------------------------------------  
GENERAL INSTRuCTIONS  
- Excessive brush wear  
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.  
Periodically inspect the commutator, slip rings, and  
brushes by removing the covers. DO NOT remove or  
replace these covers while the machine is running.  
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.  
2. “Current Range Selector” contacts should not be  
greased. To keep the contacts clean, rotate the cur-  
rent control through its entire range frequently.  
Good practice is to turn the handle from maximum  
to minimum setting twice each morning before start-  
ing to weld.  
3. Put a drop of oil on the “Current Range Selector”  
shaft at least once every month.

MAINTENANCE  
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 mainte-  
nance 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.  
PuRGING AIR FROM FuEL SYSTEM  
(PERKINS 404D-22 ENGINE)  
WARNING  
Keep fuel clear of open flames or arcs, allow  
engine to cool before working on the fuel system.  
Wipe up any spilled fuel and do not start engine  
until fumes clear.  
------------------------------------------------------------------------  
If the engine is running rough and you suspect air has  
been trapped in the fuel system, (e.g. the engine was  
allowed to run out of fuel) perform the following steps  
using qualified personnel:  
To seat 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 pres-  
sure 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%.  
1. Loosen by two or three turns, the vent screw  
(Figure D.1) on the fuel inlet connection.  
Arcing or excessive exciter brush wear indicates a  
possible misaligned shaft. Have an authorized Field  
Service Shop check and realign the shaft.  
Vent Screw  
IDLER MAINTENANCE  
CAuTION  
Priming  
Lever  
before doing electrical work on the idler printed  
circuit board, disconnect the battery.  
------------------------------------------------------------------------  
When installing a new battery or using a jumper bat-  
tery to start the engine, be sure the battery polarity is  
connected properly. The correct polarity is negative  
ground. Damage to the engine alternator and the  
printed circuit board can result from incorrect connec-  
tion.  
FIGuRE D.1  
2. Operate the electric fuel pump by turning the  
“Ignition” switch “ON” until fuel, free of air, flows  
from the vent point. Tighten the vent screw.  
3. Contact your Perkins Engine repair facility if prob-  
lems persist.  
1. Proper operation of the idler requires good ground-  
ing of the printed circuit board, reed switch, and  
battery.  
2. Idler solenoid is activated for low idle.  
3. If desired, the welder can be used without automat-  
ic idling by setting the “Idler” switch to the “High”  
position.  
NAMEPLATES  
Whenever routine maintenance is performed on this  
machine - or at least yearly - inspect all nameplates  
and labels for legibility. Replace those which are no  
longer clear. Refer to the parts list for the replace-  
ment item number.

GFCI MODuLE TESTING AND RESETTING  
PROCEDuRE  
The GFCI module should be properly tested at least  
once every month or whenever it is tripped. To proper-  
ly test and reset the GFCI module:  
• If the module has tripped, first carefully remove any  
load and check it for damage.  
• If the equipment has been shut down, it must be  
restarted.  
• The equipment needs to be operating at high idle  
speed and any necessary adjustments made on the  
control panel so that the equipment is providing at  
least 80 volts to the receptacle input terminals.  
• The circuit breaker for this receptacle must not be  
tripped. Reset if necessary.  
• Push the "Reset" button located on the GFCI mod-  
ule. This will assure normal GFCI operation.  
• Plug a night-light (with an "ON/OFF" switch) or other  
product (such as a lamp) into the Duplex receptacle  
and turn the product "ON".  
• Push the "Test" button located on the GFCI module.  
The night-light or other product should go "OFF".  
• Push the "Reset" button, again. The light or other  
product should go "ON" again.  
If the light or other product remains "ON" when the  
"Test" button is pushed, the GFCI module is not work-  
ing properly or has been incorrectly installed (mis-  
wired). If your GFCI module is not working properly,  
contact a qualified, certified electrician who can  
assess the situation, rewire the GFCI module if neces-  
sary or replace the device.
