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.
CALIFORNIA PROPOSITION 65 WARNINGS

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 prod-
ucts.
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.
5.e. Also see item 1.b.

WELDMARK 225
FOR ELECTRICALLY
powered equipment.
8.a. Turn off input power using the disconnect
switch at the fuse box before working on
the equipment.
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.
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.

SAFETY
iii
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 cir-
cuits. 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
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 l’eau pour le
refroidir.
e. Ne jamais toucher simultanément les parties sous tension
des porte-électrodes connectés à deux machines à souder
parce que la tension entre les deux pinces peut être le
total de la tension à vide des deux machines.
f. Si on utilise la machine à souder comme une source de
courant pour soudage semi-automatique, ces precautions
pour le porte-électrode s’applicuent aussi au pistolet de
soudage.
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 lev-
age, câbles de grue, ou autres circuits. Cela peut provoquer
des risques d’incendie ou d’echauffement des chaines et des
câbles jusqu’à ce qu’ils se rompent.
9. Assurer une ventilation suffisante dans la zone de soudage.
Ceci est particuliérement important pour le soudage de tôles
galvanisées plombées, ou cadmiées ou tout autre métal qui
produit des fumeés toxiques.
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.

SAFETY PRECAUTIONS
MACHINE GROUNDING
Because this portable engine driven welder or genera-
tor creates it’s own power, it is not necessary to con-
nect it’s frame to an earth ground, unless the machine
is connected to premises wiring (your home, shop,
etc.).
To prevent dangerous electric shock, other equip-
ment to which this engine driven welder supplies
power must:
• be grounded to the frame of the welder using a
grounded type plug, or be double insulated.
Do not ground the machine to a pipe that carries
explosive or combustible material.
------------------------------------------------------------------------
When this welder is mounted on a truck or trailer, it’s
frame must be electrically bonded to the metal frame
of the vehicle. Use a #8 or larger copper wire connect-
ed between the machine grounding stud and the
frame of the vehicle.
Where this engine driven welder is connected to
premises wiring such as that in your home or shop, it’s
frame must be connected to the system earth ground.
See further connection instructions in the section enti-
tled “Standby Power Connections”, as well as the arti-
cle on grounding in the latest 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 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
front of the welder.
SPARK ARRESTER
Some federal, state, or local laws may require that
gasoline engines be equipped with exhaust spark
arresters when they are operated in certain locations
where unarrested sparks may present a fire hazard.
The standard muffler included with this welder does
not qualify as a spark arrester. When required by local
regulations, the K894-1 spark arrester must be
installed and properly maintained.
An incorrect arrester may lead to damage to the
engine or adversely affect performance.
------------------------------------------------------------------------
TOWING
The recommended trailer for use with this equipment
for road, in-plant and yard towing by a vehicle
(1)
is
Lincoln’s K957-1. 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 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 there will be no undue
stress to the framework.
CAUTION
Do not attempt to use this equipment until you
have thoroughly read the engine manufacturer’s
manual supplied with your welder. It includes
important safety precautions, detailed engine
starting, operating and maintenance instructions,
and parts lists.
------------------------------------------------------------------------
ELECTRIC SHOCK can kill.
• Do not touch electrically live parts or
electrode with skin or wet clothing.
• Insulate yourself from work and
ground
• Always wear dry insulating gloves.
------------------------------------------------------------------------
ENGINE EXHAUST can kill.
• Use in open, well ventilated areas or
vent exhaust outside.
------------------------------------------------------------------------
MOVING PARTS can injure.
• Do not operate with doors open or
guards off.
• Stop engine before servicing.
• Keep away from moving parts.
------------------------------------------------------------------------
See additional warning information at
front of this operator’s manual.

can cause fire
or explosion.
VEHICLE MOUNTING
Improperly mounted concentrated loads may
cause unstable vehicle handling and tires or other
components to fail.
• Only transport this Equipment on serviceable
vehicles which are rated and designed for such
loads.
• Distribute, balance and secure loads so vehicle
is stable under conditions of use.
• Do not exceed maximum rated loads for compo-
nents such as suspension, axles and tires.
• Use appropriate nuts bolts and lockwashers to
attach the equipment base to the metal bed or
frame of vehicle.
• Follow vehicle manufacturer’s instructions.
------------------------------------------------------------------------
CAUTION
WELDING OUTPUT CABLES
With the engine off, connect the electrode and work
cables to the studs provided. These connections
should be checked periodically and tightened if neces-
sary. Loose connections will result in overheating of
the output studs.
When welding at a considerable distance from the
welder, be sure you use ample size welding cables.
Listed below are copper cable sizes recommended for
the rated current and duty cycle. Lengths stipulated
are the distance from the welder to work and back to
the welder again. Cable sizes are increased for
greater lengths primarily for the purpose of minimizing
cable voltage drop.
ANGLE OF OPERATION
Internal combustion engines are designed to run in a
level condition which is where the optimum perfor-
mance is achieved. The maximum angle of operation
for the engine is 15 degrees from horizontal in any
direction. If the engine is to be operated at an angle,
provisions must be made for checking and maintain-
ing the oil at the normal (FULL) oil capacity in the
crankcase in a level condition.
When operating at an angle, the effective fuel capacity
will be slightly less than the specified 9 gallons.
LIFTING
The WELDMARK 225 weighs approximately 575 lbs.
with a full tank of gasoline. A lift bail is mounted to the
machine and should always be used when lifting
machine. (Do not use lift bail if heavy accessory or
trailer attached-see warning).

HIGH ALTITUDE OPERATION
If the WELDMARK 225 will be consistently operated
at altitudes above 5000ft.(1524m), a carburetor jet
designed for high altitudes should be installed. This
will result in better fuel economy, cleaner exhaust,
and longer spark plug life. It will not
give increased
power which is decreased at higher altitudes. Engine
horsepower is reduced by 3.5% per 1000ft.(304.8m)
for altitudes above 377ft.(114.9m).
Do not operate a WELDMARK 225 with a high
altitude jet installed at altitudes below 5000 ft.
This will result in the engine running too lean and
result in higher engine operating temperatures
which can shorten engine life.
-----------------------------------------------------------------------
Contact your local Kohler Authorized Dealer for high
altitude jet kits that are available from the engine
manufacturer.
Muffler Relocation
•
Shut off welder and allow muffler to cool before
touching muffler.
-----------------------------------------------------------------------
The WELDMARK 225 is shipped with the exhaust
coming out on the left side. The exhaust can be
changed to the opposite side by removing the two
screws that hold the exhaust port cover in place and
installing the cover on the opposite side. (Operating
the WELDMARK 225 without the cover in place will
result in a higher noise level and no increase in
machine output.)

CAUTION
120 V DUPLEX RECEPTACLES
The 120V auxiliary power receptacles 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 load through the
associated receptacle.
MOTOR STARTING
Most 1.5 hp AC single phase motors can be started if
there is no load on the motor or other load connected
to the machine, since the full load current rating of a
1.5 hp motor is approximately 20 amperes (10
amperes for 240 volt motors). The motor may be run
at full load when plugged into only one side of the
duplex receptacle. Larger motors through 2 hp can be
run provided the receptacle rating as previously stated
is not exceeded. This may necessitate 240V operation
only.

The WELDMARK 225 can be permanently installed as
a standby power unit for 240V-3 wire, single phase 38
ampere service.
(Connections must be made by a licensed electri-
cian who can determine how the 120/240V power
can be adapted to the particular installation and
comply with all applicable electrical codes.) The
following information can be used as a guide by
the electrician for most applications (refer also to
the connection diagram shown in Figure 1.)
-------------------------------------------------------------------------
1. Install a double pole, double throw switch between
the power company meter and the premises
disconnect.

WELDER CONTROLS - FUNCTION AND
OPERATION
ENGINE SWITCH
The engine switch is used to Start the Engine, Select
High Idle or Auto Idle while the engine is running, and
stop the Engine.
When placed in the “OFF” position, the ignition
circuit is de-energized to shut down the engine.
When held in the “START” position, the engine
starter motor is energized.
When in “HIGH IDLE” ( ) position, the engine will
run continuously at high idle.
When in “AUTO IDLE” ( / ) position, the
engine will run continuously and the idler operates as
follows:
• Welding
When the electrode touches the work, the welding
arc is initiated and the engine accelerates to full
speed.
After welding ceases (and no auxiliary power is
being drawn), the engine will return to low idle
after approximately 10 to 14 seconds.
• 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 welding) for 10-14 seconds, the idler reduces
the engine speed to low idle.

STARTING/SHUTDOWN INSTRUCTIONS
STARTING THE ENGINE
Be sure all Pre-Operation Maintenance has been per-
formed. Also, read the Engine Owner’s Manual before
starting for the first time.
Remove all loads connected to the AC power recepta-
cles. Use the choke control as follows:
KOHLER ENGINE - Always pull the choke control out
when starting the engine; cold, warm or hot.
Turn the engine switch to the “start” position and
crank the engine until it starts. Release the switch as
soon as the engine starts, slowly return the choke
control to the full “in” position (choke open),
and turn the switch to the Auto Idle( / )
position. Do not turn the switch to the “start” position
while the engine is running because this will cause
damage to the ring gear and/or starter motor
After running at high engine speed for 10-14 seconds,
the engine will go to low idle.
Allow the engine to warm up by letting it run at low idle
for a few minutes.
STOPPING THE ENGINE
Remove all welding and auxiliary power loads and
allow engine to run at low idle speed for a few minutes
to cool the engine.
Stop the engine by placing the Engine switch in the
“OFF” position.
A fuel shut off valve is not required on the WELD-
MARK 225 because the fuel tank is mounted below
the engine.
BREAK-IN PERIOD
It is normal for any engine to use a greater amount of
oil until the break-in is accomplished. Check the oil
level twice a day during the break-in period (approxi-
mately 50 running hours).
IMPORTANT: IN ORDER TO ACCOMPLISH THIS
BREAK-IN, THE UNIT SHOULD BE
SUBJECTED TO MODERATE
LOADS, WITHIN THE RATING OF
THE MACHINE. AVOID LONG IDLE
RUNNING PERIODS. REMOVE
LOADS AND ALLOW ENGINE TO
COOL BEFORE SHUTDOWN.
The engine manufacturer’s recommendation for the
running time until the first oil change is as follows:
The oil filter is to be changed at the second oil
change. Refer to the Engine Owner’s Manual for more
information.
• Do not touch electrically live parts
of electrode with skin or wet
clothing.
• Keep flammable material away.

ment of the welding current within the select range.
For maximum output within a selected range set the
“OUTPUT” Control at 10. For minimum output within a
selected range set the “OUTPUT” Control at 5. (“OUT-
PUT” Control settings below 5 may reduce arc stabili-
ty) For best overall welding performance set the
“RANGE” Switch to the lowest setting and the OUT-
PUT” Control near the maximum to achieve the
desired welding current.
