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.  
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.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.  
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.  
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.  
3.j. Also see Items 6.c. and 8.  
5.e. Read and understand the manufacturerʼs instructions for this  
equipment and the consumables to be used, including the  
material safety data sheet (MSDS) and follow your  
employerʼs safety practices. MSDS forms are available from  
your welding distributor or from the manufacturer.

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.  
•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 manufacturerʼs  
recommendations.  
8.c. Ground the equipment in accordance with the U.S. National  
Electrical Code and the manufacturerʼs recommendations.

SAFETY  
5. Toujours porter des lunettes de sécurité dans la zone de  
soudage. Utiliser des lunettes avec écrans lateraux dans les  
zones où lʼon 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 suiv-  
antes:  
6. Eloigner les matériaux inflammables ou les recouvrir afin de  
prévenir tout risque dʼincendie 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 dʼincendie.  
Sûreté Pour Soudage A LʼArc  
1. Protegez-vous contre la secousse électrique:  
a. Les circuits à lʼélectrode 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 sʼisoler 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.  
d.Ne jamais plonger le porte-électrode dans lʼeau 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 sʼapplicuent aussi au pistolet de  
soudage.  
8. Sʼassurer que la masse est connectée le plus prés possible  
de la zone de travail quʼil est pratique de le faire. Si on place  
la masse sur la charpente de la construction ou dʼautres  
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 dʼincendie ou dʼechauffement des chaines et des  
câbles jusquʼà ce quʼils 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.  
10. Ne pas souder en présence de vapeurs de chlore provenant  
dʼopérations de dégraissage, nettoyage ou pistolage. La  
chaleur ou les rayons de lʼarc peuvent réagir avec les vapeurs  
du solvant pour produire du phosgéne (gas fortement toxique)  
ou autres produits irritants.  
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 nʼimporte quelle partie  
du corps.  
PRÉCAUTIONS DE SÛRETÉ POUR  
LES MACHINES À SOUDER À  
TRANSFORMATEUR ET À  
REDRESSEUR  
3. Un coup dʼarc peut être plus sévère quʼun coup de soliel,  
donc:  
a. Utiliser un bon masque avec un verre filtrant approprié  
ainsi quʼun verre blanc afin de se protéger les yeux du ray-  
onnement de lʼarc et des projections quand on soude ou  
quand on regarde lʼarc.  
b. Porter des vêtements convenables afin de protéger la  
peau de soudeur et des aides contre le rayonnement de  
lʻarc.  
c. Protéger lʼautre personnel travaillant à proximité au  
soudage à lʼaide dʼécrans appropriés et non-inflammables.  
1. Relier à la terre le chassis du poste conformement au code de  
lʼélectricité 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, Iʼinstallation et lʼentretien du poste seront  
effectués par un électricien qualifié.  
4. Des gouttes de laitier en fusion sont émises de lʼarc de  
soudage. Se protéger avec des vêtements de protection libres  
de lʼhuile, tels que les gants en cuir, chemise épaisse, pan-  
talons sans revers, et chaussures montantes.  
3. Avant de faires des travaux à lʼinterieur de poste, la debranch-  
er à lʼinterrupteur à la boite de fusibles.  
4. Garder tous les couvercles et dispositifs de sûreté à leur  
place.

sibility 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:  
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 that there will be no  
undue stress to the trailerʼs framework.

ENGINE BREAK-IN  
WARNING: Use caution as the electrolyte is a  
strong acid that can burn skin and damage eyes.  
Lincoln Electric selects high quality, heavy-duty indus-  
trial 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, wetstacking (oil or tar like sub-  
stance at the exhaust port), or excessive smoke is not  
normal.  
Remove and discard the insulating caps from the neg-  
ative battery terminals. Attach and tighten negative  
battery cable terminals.  
NOTE: This machine is furnished with wet charged  
batteries; if unused for several months, the batteries  
may require a booster charge. Be careful to charge  
the batteries with the correct polarity. Make sure that  
the batteries are level while charging.  
Larger machines with a capacity of 350 amperes and  
higher, which are operated at low or no-load condi-  
tions for extended periods of time are especially sus-  
ceptible to the conditions described above. To  
accomplish successful engine break-in, most diesel-  
powered equipment needs only to be run at a reason-  
ably heavy load within the rating of the welder for  
some period of time during the engineʼs early life.  
However, if the welder is subjected to extensive light  
loading, occasional moderate to heavy loading of the  
engine may sometimes be necessary. Caution must  
be observed in correctly loading a diesel/generator  
unit.  
WARNING  
GASES FROM BATTERY can explode.  
Keep sparks, flame and cigarettes  
away from battery.  
To prevent EXPLOSION when:  
INSTALLING A NEW BATTERY — disconnect  
negative cable from old battery first and con-  
nect to new battery last.  
CONNECTING A BATTERY CHARGER —  
remove battery from welder by disconnecting  
negative cable first, then positive cable and  
battery clamp. When reinstalling, connect  
negative cable last. Keep well ventilated.  
1. Connect the welder output studs to a suit-  
able resistive load bank. Note that any  
attempt to short the output studs by con-  
necting the welding leads together, direct  
shorting of the output studs, or connecting  
the output leads to a length of steel will  
result in catastrophic damage to the gener-  
ator and voids the warranty.  
USING A BOOSTER — connect positive lead to  
battery first then connect negative lead to neg-  
ative battery lead at the lower control panel  
support.  
2. Set the welder controls for an output cur-  
rent 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.  
BATTERY ACID can burn eyes and  
skin.  
Wear gloves and eye protection  
and be careful when working near  
battery.  
Follow instructions printed on battery.  
3. Periodically shut off the engine and check  
the crankcase oil level.  
IMPORTANT: To prevent ELECTRICAL DAMAGE  
WHEN:  
ENGINE COOLING SYSTEM  
a) Installing new batteries.  
b) Using a booster.  
The cooling system has been filled at the factory with  
a 50-50 mixture of ethylene glycol antifreeze and

MACHINE GROUNDING  
Because this portable engine driven welder creates its  
own power, it is not necessary to connect its frame to  
an earth ground, unless the machine is connected to  
premises wiring (home, shop, etc.).

or  
b) be double insulated.  
Some federal, state or local laws may require that  
diesel engines be equipped with exhaust spark  
arrestors when they are operated in certain locations  
where unarrested sparks may present a fire hazard.  
The welder was shipped from the factory with a sepa-  
rate spark arresting unit. If a spark arrestor is required  
secure the spark arrestor to the outlet tube of the muf-  
fler using the clamp provided. Any spark arrestor must  
be serviced and properly maintained.  
When this welder is mounted on a truck or trailer, its  
frame must be securely connected to the metal frame  
of the vehicle. When this engine driven welder is con-  
nected to premises wiring such as that in a home or  
shop, its frame must be connected to the system earth  
ground. See the article on grounding in the latest U.S.  
National Electrical Code and the local code.  
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 a metal water pipe going into  
the ground for at least ten feet and having no insulat-  
ed 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. A machine

OPERATION  
ENGINE CONTROLS  
ENGINE PROTECTION SYSTEM  
IGNITION SWITCH  
The engine protection system shuts down the engine  
under high coolant temperature or low engine oil pres-  
sure conditions by allowing the fuel solenoid valve to  
close.  
When placed in the “ON” position, this switch ener-  
gizes the fuel solenoid. When placed in the “OFF”  
position, the flow of fuel to the injection pump is  
stopped to shut down the engine.  
AIR INTAKE SHUT-OFF  
“IDLER” SWITCH  
The air intake shut-off is a automatic/manually device  
which blocks all intake air from entering the engine.  
The idler switch has two positions, “HIGH” and  
“AUTO”.  
The automatic feature of the shut-off will engage  
should excessive over speeding occur. The valve is  
calibrated at the factory to shutdown within the safety  
When in “HIGH” (  
) position, the engine will run  
continuously at high idle.  
To manually shut down the engine, simply pull the  
emergency stop handle on the lower control panel.  
When in “AUTO” (  
/ ) idle position, the idler  
operates as follows:  
The air intake shut-off device will reset automatically,  
generally within one minute.  
a. Welding  
When the electrode touches the work, the welding  
arc is initiated and the engine accelerates to full  
speed.  
WARNING  
Muffler and Engine may be hot!  
After welding ceases (and no auxiliary power is  
being drawn), the engine will return to low idle after  
approximately 10 to 14 seconds.  
b. Auxiliary Power  
With the engine running at low idle and auxiliary  
power for lights or tools is drawn (approximately  
100-150 watts or greater) from the receptacles, the  
engine will accelerate to high speed. If no power is  
being drawn from the receptacles ( and not weld-  
ing) for 10-14 seconds, the idler reduces the  
engine speed to low idle.  
IMPORTANT: Before restarting engine, verify that the  
air intake shut-off is in the open position. DO NOT  
ATTEMPT TO START ENGINE WITH THE AIR  
INTAKE SHUT-OFF IN THE CLOSED POSITION.  
This may cause severe damage to the engine.  
ENGINE TEMPERATURE GAUGE  
Displays the coolant temperature in the engine block.  
ENGINE OIL PRESSURE GAUGE  
Displays the oil pressure to the engine. When the  
engine starts running, watch for the oil pressure to  
build up. If no pressure shows within 30 seconds, stop  
the engine and consult the engine instruction manual.  
BATTERY CHARGING AMMETER  
Displays the current going from the charging alterna-  
tor into the batteries. It is normal for charging current  
to be high (above 15 amps) after starting or when the  
batteries are ʻlowʼ on charge.

OPERATION  
4. If you want a little more current, turn the “Job  
Selector” up (counterclockwise) to increase cur-  
rent. If you want a little less current, turn the “Job  
Selector” down (clockwise) to decrease current.  
WELDER CONTROLS  
POLARITY SWITCH  
Turn the Arc Polarity switch to electrode positive or  
electrode negative as required for each particular  
application.  
5. If dialing the desired current with the “Job  
Selector” moves the setting outside the black  
range causing undesirable arc characteristics,  
turn the “Job Selector” back to the center of the  
black range. Then turn the “Current Control” up or  
down a little as needed. Readjust the “Job  
Selector” for the exact characteristics and current  
desired.  
CONTROL OF WELDING CURRENT  
Purpose of Controls  
The continuous “Current Control” is the main current  
adjuster. The “Job Selector” is both a fine current  
adjuster and the continuous Open Circuit Voltage  
adjuster. Open Circuit Voltage (OCV) controls the arc  
characteristics.  
REMOTE CONTROL  
“Job Selector”  
A receptacle and “Local/Remote” control switch on the  
lower front control panel and a remote control box with  
100 ft. (30.5 m) of cord for adjusting the OCV at the  
welding site are standard. Putting the switch in the  
“REMOTE” position allows fine current control at the  
remote control box while placing the switch in the  
“LOCAL” position allows fine current control at the  
“Job Selector” on the machine.  
The “Job Selector” dial is divided into four colored  
sections providing OCV ranges as follows:  
Color  
Title  
OCV Range  
High OCV  
White  
Large Electrodes  
Normal Welding  
Black  
Red  
Medium OCV  
Overhead & Vertical Low OCV  
Grey  
Special Applications Extra-Low OCV  
The “Job Selector” is usually set in the black range  
because it provides a soft “Buttering “ arc desired for  
most welding. Some operators prefer to set the “Job  
Selector” in the red range for a snappy “Digging” arc  
when welding vertical up or overhead.  
AUXILIARY POWER CONTROLS  
Note: GFCI receptacles our an option and if installed,  
see the “MAINTENANCE SECTION” for  
detailed information on testing and resetting the  
GFCI receptacle.

Do not adjust the “Current Control” while welding  
One 20 amp, 115 VAC duplex receptacle provides  
115 VAC for auxiliary power. A total of 26 amps can  
be drawn from this receptacle.  
because this can damage the control.  
------------------------------------------------------------------------  
The “Current Control” dial is calibrated in amperes on  
three separate colored dials corresponding to the  
white, black and red ranges of the “Job Selector” dial.  
For example: when the “Job Selector” is set on the  
black range, the approximate welding current is indi-  
cated on the black scale of the “Current Control” dial.  
230 VAC Receptacle  
One 15 amp, 230 VAC duplex receptacle provides  
230 VAC for auxiliary power. A total of 13 amps can  
be drawn from this receptacle.  
How to Set the Controls  
Circuit Breakers  
Assume you want a normal soft arc and about 135  
amps, using a 5/32” (4.0 mm) electrode:  
The circuit breakers provide separate overload current  
protection for each half of the 115 V duplex recepta-  
cle. The circuit breakers provide overload current pro-  
tection in both current carrying wires of the 230 V  
duplex receptacle.  
1. Set the “Job Selector” at the center of the black  
range.  
2. Set the “Current Control” to read 135 amps on the  
black dial.

eral minutes to warm the engine. Stop the engine  
and recheck the oil level, after allowing sufficient  
time for the oil to drain into the pan. If the level is  
down, fill it to the full mark again. The engine con-  
trols were properly set at the factory and should  
require no adjusting when received.

ing fluids be used!  
------------------------------------------------------------------------  
• Stop engine before servicing.  
• Keep away from moving parts.  
------------------------------------------------------------------------  
With a fully charged battery and the proper weight oil,  
the engine should start satisfactorily even down to  
about -5°F (-20°C), it maybe desirable to install cold-  
starting aides.  
See additional warning information at the  
front of this operatorʼs manual.  
Note: Extreme cold weather staring may require  
longer glow plug operation.  
For added safety always operate the welder with the  
doors closed. Further, leaving the doors open  
changes the designed air flow and may cause engine,  
generator overheating.  
STOPPING THE ENGINE  
1. Turn the “IGNITION” switch to “OFF”  
CAUTION  
At the end of each dayʼs welding, check the crankcase  
oil level, drain accumulated dirt and water from the  
water separator and refill the fuel tank to minimize  
moisture condensation in the tank. Also, running out  
of fuel tends to draw dirt into the fuel system.  
Do not adjust the high idle engine speed (rpm)  
above the factory setting specification as this will  
void warranty.  
------------------------------------------------------------------------  
STARTING INSTRUCTIONS  
Be sure all Pre-Operation Maintenance has been  
performed. (See INSTALLATION section of this  
manual).  
When hauling the welder between job sites, close the  
fuel shut-off valve.  
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-  
nel to do this per the instructions in the MAINTE-  
NANCE section of this manual.  
1. Turn the “IDLER” switch to “HIGH”.  
2. Turn the “IGNITION” switch to “ON”.

service this equipment.  
ROUTINE MAINTENANCE  
At the end of each dayʼs welding, refill the fuel tank to  
minimize moisture condensation in the tank. Also, run-  
ning out of fuel tends to draw dirt into the fuel system.  
Check the engine crankcase oil level.  
ENGINE AIR FILTER  
If the fuel supply runs out while the fuel pump is oper-  
ating, air may be entrapped in the fuel distribution sys-  
tem. If this happens, bleeding of the fuel system may  
be necessary. See the engine instruction manual.  
The engine air filter element is a dry cartridge type. It  
is located above the engine. It can be cleaned and re-  
used; however, damaged elements should not be  
washed or re-used. Remove loose dirt from element  
with compressed air or water hose directed from  
inside out. Compressed Air: 100 psi maximum. The fil-  
ter should never be removed while the engine is run-  
ning.  
PERIODIC MAINTENANCE  
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. The current control reactor brushes are self-lubricating  
and should not be greased. Keep the contacts clean.  
This control should be moved from maximum to mini-  
mum daily to prevent the controls from sticking.  
3. See the engine Instruction Manual for periodic engine  
maintenance information. Change the oil filter in accor-  
dance with the instructions in the engine operating man-  
ual. When the oil filter is changed add one quart of oil to  
the crankcase to replace the oil held in the filter during  
operation.

MAINTENANCE  
BEARING MAINTENANCE  
To seat the slip ring brushes, position the brushes in  
place. Then slide one end of a piece of fine sandpa-  
per between slip rings and brushes with the coarse  
side against 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%.  
This welder is equipped with a double-shielded ball bearing  
having sufficient grease to last indefinitely under normal ser-  
vice. 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.  
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.  
COOLING SYSTEM  
COMMUTATOR AND BRUSH MAINTENANCE  
The SAE-400 SEVERE DUTY is equipped with a  
pressure radiator. Keep the radiator cap tight to pre-  
vent loss of coolant. Clean and flush the cooling sys-  
tem periodically to prevent clogging the passage and  
overheating the engine. When antifreeze is needed,  
always use the permanent type.  
WARNING  
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.  
------------------------------------------------------------------------  
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.  
WARNING  
FUEL FILTERS  
When working on the fuel system  
• Keep ungrounded lights away, do not  
smoke !  
Shifting of the brushes may result in:  
- Change in machine output  
- Commutator Damage  
• Do not spill fuel !  
- Excessive brush wear  
------------------------------------------------------------------------  
The SAE-400 SEVERE DUTY is equipped with a Fuel  
Pre-Filter/Water Separator Assembly located before  
the lift pump and a Secondary Fuel Filter located  
after the lift pump and before the fuel injectors. The  
Fuel Pre-Filter/Water Separator is mounted to the  
engine block just below the lift pump.  
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.  
The Secondary Fuel Filter is mounted directly to the  
engine just above the oil filter.  
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.  
FUEL PRE-FILTER/WATER SEPARATOR ASSEMBLY  
The pre-filter is a 150 micron screen designed to pro-  
tect against gross fuel contamination of the water sep-  
arator element and the Secondary Fuel Filter. If the  
pre-filter becomes plugged it may be removed,  
inspected, cleaned and reinstalled. In general this  
only needs to be done with each water separator ele-  
ment change (about every 1,000 hrs.) However if at  
any time excessive fuel contamination is suspected or  
a sudden fall-off in engine performance is detected  
the pre-filter screen should be inspected and cleaned.  
Follow the following procedure:  
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.

MAINTENANCE  
1. Close the fuel shutoff valve located under the fuel  
tank.  
3. Grasp the element and pull down with a slight rock-  
ing motion to remove the element from the grom-  
met post on the bottom of the filter header.  
2. Unscrew the cap ring located on the top of the filter  
header and remove the plastic center cap and O-  
ring.  
4. Slide the new element onto the grommet post on the  
bottom of the filter header until the element no longer  
easily moves up into the filter header. Now rotate the  
element (may take almost 1 full turn) with a slight  
upward pressure until the element begins to further  
engage the header. With the proper orientation now  
established apply additional pressure to seat the ele-  
ment in the filter header. You should feel the element  
“pop” into place when properly seated.  
3. Remove the large white volume plug located  
directly under the center cap in the upper cavity of  
the filter header. Use a small screwdriver (or simi-  
lar device) to lift the plug part way out of the cavity  
to assist with its removal.  
Be careful not to damage the pre-filter screen  
with the tool used to remove the plug.  
Note: The element will only go on one way. Never  
use excessive force when mounting the element to  
the header.  
4. Using a pair of pliers, gently tug on the pull tabs of  
the pre-filter screen in an alternating pattern to  
gradually remove the pre-filter screen.  
5. Slide the quick change ring up over the element and  
rotate counter clockwise until an audible click or pop  
is heard. If you do not hear the click you have not  
rotated the ring far enough and the element is not in  
the locked position. Another indication that the ring is  
in the locked position is that one set (it doesnʼt matter  
which one) of arrows located on the outside of the  
ring should be located directly under the air vent  
valve.  
5. Brush off any debris and rinse in diesel fuel.  
6. Re-install the pre-filter screen into the upper cavity  
of the filter header making sure the four pull tabs  
are pointing up. Putting your fingers on the pull  
tabs, push down evenly until the lower body of the  
pre-filter screen contacts the floor of the upper cav-  
ity.  
6. Open the fuel shutoff valve.  
7. Open the air vent valve on the front of the filter header  
until fuel emerges free of air bubbles and then close  
the air vent valve.  
7. Re-insert the large white volume plug into the  
upper cavity.  
Note : Consult your engine operation manual for infor-  
mation on air bleeding the entire fuel system.  
8. Place the O-ring onto the angled seal surface of  
the filter header and re-install the plastic cap. Make  
sure its flange rests on the O-ring.  
SECONDARY FUEL FILTER  
9. Screw on the cap ring and tighten hand tight.  
The Secondary Fuel Filter has a quick change element  
mounted to the engine similar to the Water Separator.  
Consult your engine operation manual for complete infor-  
mation on service intervals and element changing proce-  
dures.
