WARNING
Mar ‘95
ELECTRIC AND
MAGNETIC FIELDS
may be dangerous
2.a. Electric current flowing through any conductor causes
localized Electric and Magnetic Fields (EMF). Welding
current creates EMF fields around welding cables and
welding machines
2.b. EMF fields may interfere with some pacemakers, and
welders having a pacemaker should consult their physician
before welding.
2.c. Exposure to EMF fields in welding may have other health
effects which are now not known.
2.d. All welders should use the following procedures in order to
minimize exposure to EMF fields from the welding circuit:
2.d.1.
Route the electrode and work cables together - Secure
them with tape when possible.
2.d.2. Never coil the electrode lead around your body.
2.d.3. Do not place your body between the electrode and
work cables. If the electrode cable is on your right
side, the work cable should also be on your right side.
2.d.4. Connect the work cable to the workpiece as close as
possible to the area being welded.
2.d.5. Do not work next to welding power source.
1.h. To avoid scalding, do not remove the
radiator pressure cap when the engine is
hot.

ARC RAYS can burn.
4.a. Use a shield with the proper filter and cover
plates to protect your eyes from sparks and
the rays of the arc when welding or observing
open arc welding. Headshield and filter lens
should conform to ANSI Z87. I standards.
4.b. Use suitable clothing made from durable flame-resistant
material to protect your skin and that of your helpers from
the arc rays.
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.
ELECTRIC SHOCK can 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.
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.
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:
• Semiautomatic DC Constant Voltage (Wire) Welder.
• DC Manual (Stick) Welder.
• AC Welder with Reduced Voltage Control.
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.
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.
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.
FUMES AND GASES
can be dangerous.
5.a.Welding may produce fumes and gases
hazardous to health. Avoid breathing these
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.
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.
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.
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.

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.
CYLINDER may explode
if damaged.
7.a. Use only compressed gas cylinders
containing the correct shielding gas for the
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.
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.
7.d. Never allow the electrode, electrode holder or any other
electrically “hot” parts to touch a cylinder.
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.
Mar ‘95
WELDING SPARKS can
cause fire or explosion.
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.
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.
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.
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.
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).
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.
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.

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:
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.
b. Faire trés attention de bien s’isoler de la masse quand on
soude dans des endroits humides, ou sur un plancher met-
allique 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 defonc-
tionnement.
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 soud-
er parce que la tension entre les deux pinces peut être le
total de la tension à vide des deux machines.
f. Si on utilise la machine à souder comme une source de
courant pour soudage semi-automatique, ces precautions
pour le porte-électrode s’applicuent aussi au pistolet de
soudage.
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.
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.
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.
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.
5. Toujours porter des lunettes de sécurité dans la zone de
soudage. Utiliser des lunettes avec écrans lateraux dans les
zones où l’on pique le laitier.
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.
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.
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.
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.
PRÉCAUTIONS DE SÛRETÉ POUR
LES MACHINES À SOUDER À
TRANSFORMATEUR ET À
REDRESSEUR
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.
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.

------------------------------------------------------------------------
MOVING PARTS can injure.
•Do not operate with doors open or
guards off.
•Stop engine before servicing.
•Keep away from moving parts
------------------------------------------------------------------------
Only qualified personnel should install, use or service
this equipment
LOCATION/VENTILATION
The welder should be located to provide an unrestricted
flow of clean, cool air to the cooling air inlets and to avoid
restricting the cooling air outlets. Also, locate the welder
so that the engine exhaust fumes are properly vented to
an outside area.
STACKING
SAE400 WELD’N AIR machines cannot be stacked.
ANGLE OF OPERATION
To achieve optimum engine performance the SAE400
WELD’N AIR should be run in a level position. The
maximum angle of operation for the air compressor is
20 degrees in all directions. If the compressor is to be
operated at an angle, provisions must be made for
checking and maintaining the oil level at the normal
(FULL) oil capacity in the compressor crankcase. The
maximum angle of operation for the Perkins engine is
45 degrees in all directions. If the engine is to be oper-
ated at an angle, provisions must be made for check-
ing and maintaining the oil level at the normal (FULL)
oil capacity in the engine crankcase. When operating
the welder at an angle, the effective fuel capacity will
be slightly less than the specified 22.5 gallons.
LIFTING
The SAE400 WELD’N AIR lift bale should be used to
lift the machine.
FALLING EQUIPMENT can cause
injury.
•Do not lift this machine using lift bale 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.

As a rule of thumb, derate the welder output 5% for
every 500 meters (1640 ft.) above 1000 meters (3280
ft.).
Contact a Perkins Service Representative for any
engine adjustments that may be required for high alti-
tude operation.
TOWING
The recommended trailers for use with this equipment
for in-plant and yard towing by a vehicle
(1)
are Lincoln’s
K767-1, K956-1 and K956-2. The K956-1 and K956-2
are also designed to be used at highway speeds
(1)
.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 consid-
ered 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 trailer’s framework.
3. Proper placement of the equipment on the trailer to
insure stability side to side and front to back when
being moved and when standing by itself.
4.Typical conditions of use, such as travel speed,
roughness of surface on which the trailer will be
operated, and environmental conditions.
5. Proper preventative maintenance of trailer.
6. Conformance with federal, state and local laws.

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.).
To prevent dangerous electric shock, other equipment
powered by this engine driven welder must:
a) be grounded to the frame of the welder using a
grounded type plug,
or
b) be double insulated.
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 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. A machine grounding
stud marked with the symbol is provided on the
welding generator frame foot.

ENGINE CONTROLS
IGNITION SWITCH
When placed in the “ON”position, this switch energizes
the fuel solenoid. When placed in the “OFF” position,
the flow of fuel to the injection pump is stopped to shut
down the engine.
SPEED CONTROL LEVER
Manually allows the engine to run at its high idle speed
controlled by the governor or at the factory set low idle
speed. When welding, using air compressor or using
auxiliary power the speed control lever must be in the
“RUN” position.To reduce the engine to low idle speed
when not welding, not using the compressor or not
using auxiliary power place the speed control lever in
the “IDLE” position notch.
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 alternator
into the batteries.It is normal for charging current to be
high (above 15 amps) after starting or when the batter-
ies are ‘low’ on charge.
ENGINE HOUR METER
The engine hour meter records the total running time
on the engine in hours.It can be used to keep a record
of maintenance on the engine and or welder.
ENGINE PROTECTION SYSTEM
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.
WELDER CONTROLS
POLARITY SWITCH
Turn the Arc Polarity switch to electrode positive or
electrode negative as required for each particular
application.
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.
“Job Selector”
The “Job Selector” dial is divided into four colored sec-
tions providing OCV ranges as follows:
Color Title OCV Range
White Large Electrodes High OCV
Black Normal Welding Medium OCV
Red 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.
“Current Control”
Do not adjust the “Current Control” while welding
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.

How to Set the Controls
Assume you want a normal soft arc and about 135
amps, using a 5/32” (4.0 mm) electrode:
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.
3. Start to weld.
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.
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.
REMOTE CONTROL
A receptacle and “Local/Remote” control switch on the
lower front control panel and a remote control box with
25 ft.(7.6 m) of 3-conductor cord for adjusting the OCV
at the welding site. Putting the switch in the “REMOTE”
position allows fine current control at the remote con-
trol box while placing the switch in the “LOCAL” position
allows fine current control at the “Job Selector” on the
machine. When using the optional field installed CV
adapter (K385-1) the “Local/Remote” switch is only
active in the “VV” mode.
AUXILIARY POWER CONTROLS
115 VAC Receptacle
One 15 amp, 115 VAC duplex receptacle provides 115
VAC for auxiliary power. A total of 26 amps can be
drawn from this receptacle.
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.
15 AMP Circuit Breakers
These circuit breakers provide separate overload cur-
rent protection for each half of the 115 V duplex recep-
tacle.The circuit breakers provide overload current pro-
tection in both current carrying wires of the 230 V
duplex receptacle.
Ground Stud
Provides a connection point for connecting the
machine to earth ground.For the safest grounding pro-
cedure refer to “Machine Grounding” in the INSTALLA-
TION section of this manual.
AIR COMPRESSOR CONTROLS
COMPRESSOR ON/OFF SWITCH
Placing the “ON/OFF” switch in the “ON” position
allows the “pressure switch” (factory preset) to control
the air compressor through an electric clutch.When the
system pressure falls below 90 psi, the “pressure
switch” engages the clutch and compressor. When the
system pressure goes above 130 psi, the “pressure
switch” disengages the clutch and compressor.
The “ON/OFF” switch needs to be in the “ON” position
when using compressed air.When placed in the “OFF”
position this switch does not allow the compressor
clutch to engage regardless of the tank pressure.
The “ON/OFF” switch should be in the “OFF” position
while starting the engine.This will minimize the load on
the starter motor.
COMPRESSOR OPERATING LIGHT
This light is on when the compressor “ON/OFF” switch
is in the “ON” position.
COMPRESSOR AIR PRESSURE GAUGE
This gauge displays the air pressure in the air receiver
tanks.
COMPRESSOR OIL PRESSURE GAUGE
This gauge displays the compressor oil pressure.Oil is
under pressure only when the compressor clutch is
engaged.

ENGINE OPERATION
Do not adjust the high idle engine speed (rpm) above
the factory setting specification as this will overspeed
the air compressor and void it’s warranty.
------------------------------------------------------------------------
STARTING INSTRUCTIONS
Be sure all Pre-Operation Maintenance has been per-
formed. (See INSTALLATION section of this manual).
Set the air compressor “ON/OFF” switch in the “OFF”
position.To start the engine, set the speed control lever
in the “RUN” position. Place ignition toggle switch in
the “ON” position. Push in the engine protection sys-
tem reset button.Engage the starter button. When the
engine starts running, observe the engine oil pressure.
If no pressure shows within 30 seconds, stop the
engine and consult the engine operating manual. To
stop the engine, place the ignition toggle switch in the
“OFF” position.
When an engine is started for the first time, some of the
oil will be needed to fill the passages of the lubricating
system. Therefore, on initial starting, run the engine for
about five minutes and then stop the engine and
recheck the oil. If the level is down, fill to the full mark
again.The engine controls were properly set at the fac-
tory and should require no adjusting when received.
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
or compressor overheating.
Cold Weather Starting
Never use any other starting aids, such as ether, when
using the “Thermostart” system.
------------------------------------------------------------------------
When overnight temperatures are between 10°F (-
12°C) and freezing, use the standard “Thermostart”
starting system installed on all engines. Follow the
instructions on the start panel 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 0°F (-18°C).
If the engine must be frequently started below 10°F
(-12°C), 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.
BREAK-IN PERIOD
ENGINE
The engine used to supply power for your welder is a
heavy duty, industrial engine. It is designed and built
for rugged use. It is very normal for any engine to use
small quantities of oil until the break-in is accom-
plished. Check the oil level twice a day during the
break-in period (about 100 running hours).
IMPORTANT: IN ORDER TO ACCOMPLISH THIS
BREAK-IN, THE UNIT SHOULD BE SUBJECTED TO
HEAVY LOADS, WITHIN THE RATING OF THE
MACHINE. AVOID LONG IDLE RUNNING PERIODS.
AIR COMPRESSOR
Cylinder head stud torque must be checked after initial
8 to 10 hours of operation. See compressor operator’s
manual for details. Compressor mounting bolts should
be checked for tightness after initial 8 to 10 hours of
operation.
