The Above For Gasoline Engines

i

FOR ENGINE
powered equipment.

1.a. Turn the engine off before troubleshooting and maintenance
work unless the maintenance work requires it to be running.

____________________________________________________

1.b.Operate engines in open, well-ventilated
areas or vent the engine exhaust fumes
outdoors.

____________________________________________________

1.c. Donot add the fuel near an openflame weld­ing arc or when the engine is running. Stop
the engine and allow it to cool before refuel­ing to prevent spilled fuel from vaporizing on
contact with hot engine parts and igniting. Do
not spill fuel when fillingtank. If fuel is spilled,
wipe it up and do not start engine until fumes
have been eliminated.

____________________________________________________

1.d. Keepall equipment safety guards,covers and devicesin posi­tion and in good repair.Keep hands, hair, clothing and tools
away from V-belts, gears, fans and all other moving parts
when starting, operating or repairing equipment.

____________________________________________________

1.e. In some cases it may be necessary to remove safety

guards to perform required maintenance. Remove
guards only when necessary and replace them when the
maintenance requiring their removal is complete.
Always use the greatest care when working near moving
parts.

___________________________________________________

1.f. Do not put your hands near the engine fan.
Do not attempt to override the governor or
idler by pushing on the throttle control rods
while the engine is running.

1.h. To avoid scalding, do not remove the
radiator pressure cap when the engine is
hot.

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.

___________________________________________________

1.g. To prevent accidentally starting gasoline engines while
turning the engine or welding generator during maintenance
work, disconnect the spark plug wires, distributor cap or
magneto wire as appropriate.

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.

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.

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.

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. The operation of welding fume control equipment is affected
by various factors includingproper use and positioningof the
equipment, maintenance of the equipment and the specific
welding procedure and application involved. Worker expo­sure level should be checked upon installation and periodi­cally thereafter to becertain it is withinapplicable OSHAPEL
and ACGIH TLV limits.

5.c.

Do not weld in locations near chlorinated hydrocarbon
coming from degreasing, cleaning or spraying operations.
The heat and rays of the arc can react with solvent vapors
form phosgene, a highly toxic gas, and other irritating prod­ucts.

vapors

to

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.

WELDING and CUTTING
SPARKS can
cause fire or explosion.

6.a.

Remove fire hazards from the welding area.

If this is not possible, cover them to prevent

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
been “cleaned”. For information, purchase “Recommended
Safe Practices for the
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.

Sparks and spatter are thrown from the welding arc. Wear oil

6.f.
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 alternatecircuits.
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 suiv­antes:

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 planchermet­allique 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 demasse, 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 entreles 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.

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 charpentede 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.

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-électrodeautour de n’importe quelle partie du
corps.

3. Un coup d’arc peut êtreplus sévère qu’uncoup de soliel,donc:

a. Utiliser un bonmasque avec unverre filtrantapproprié ainsi

qu’un verre blanc afin de se protéger les yeux du rayon­nement de l’arc et des projections quand on soude ou
quand on regarde l’arc.

b. Porter desvêtements 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, pan­talons 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.

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 debranch­er à l’interrupteur à la boite de fusibles.

4. Garder tous les couvercles et dispositifs de sûreté à leur place.

SAFETY PRECAUTIONS

WARNING

Do not attempt to use this equipment until you
have thoroughly read all operating and mainte­nance manuals supplied with your machine. They
include important safety precautions, detailed
engine starting, operating and maintenance
instructions and parts lists.

ELECTRIC SHOCK can kill.

•Do not touch electrically live parts
such as output terminals or internal
wiring.

•Insulate yourself from the work and
ground.

•Always wear dry insulating gloves.

------------------------------------------------------------------------

ENGINE EXHAUST can kill.

•Use in open, well ventilated areas or
vent exhaust outside

CAUTION

DO NOT MOUNT OVER COMBUSTIBLE SURFACES
Where there is a combustible surface directly
under stationary or fixed electrical equipment, that
surface should be covered with a steel plate at
least .06”(1.6mm) thick, which should extend not
less than 5.90(150mm) beyond the equipment on
all sides.

------------------------------------------------------------------------

STACKING

These machines cannot be stacked.

ANGLE OF OPERATION

To achieve optimum engine performance the machine
should be run in a level position. The maximum angle
of operation for the Kubota engine is 20 degrees con­tinuous in all directions and 30 degrees intermittent
(less than 10 minutes). If the engine 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 engine crankcase. When operating the welder
at an angle, the effective fuel capacity will be slightly
less than the specified 29 gallons.

LIFTING

•Do not stack anything near the
engine.

------------------------------------------------------------------------

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.

The equipment lift bail should be used to lift the
machine.

WARNING

• Lift only with equipment of adequate
lifting capacity.

• Be sure machine is stable when lift­ing.

• Do not lift this machine using lift bail
if it is equipped with a heavy acces­sory such as a trailer or gas cylinder.

FALLING • Do not lift machine if lift bail is

EQUIPMENT can damaged.

Cause injury. • Do not operate machine while

Suspended from lift bail.

HIGH ALTITUDE OPERATION

At higher altitudes, output derating may be necessary.
For maximum rating, derate the welder output 5% for
every 500 meters (1640 ft.) above 400 meters (1312
ft.).

Contact a Kubota Service Representative for any
engine adjustments that may be required for high alti­tude operation.

TOWING

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 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.

VEHICLE MOUNTING

WARNING

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 compo­nents such as suspension, axles and tires.

• Mount equipment base to metal bed or frame of
vehicle.

• Follow vehicle manufacturer’s instruction.

------------------------------------------------------------------------

PRE-OPERATION ENGINE SERVICE

READ the engine operating and maintenance instruc­tions supplied with this machine.

ENGINE OIL

The engine is shipped with the engine crankcase filled
with high quality SAE 10W-30 oil (API class CD or bet­ter). Check the oil level before starting the engine. If it is
not up to the full mark on the dip stick, add oil as required.
Check the oil level every four hours of running time during
the first 35 running hours. Refer to the engine Operator’s
Manual for specific oil recommendations and break-in
information. The oil change interval is dependent on the
quality of the oil and the operating environment. Refer to
the engine Operator’s Manual for the proper service and
maintenance intervals.

5. Proper preventative maintenance of trailer.

6. Conformance with federal, state and local laws.

(1)

For highway use, consult applicable federal, state
and local laws regarding specific requirements for
use on public highways, such as brakes, lights, fend­ers, etc.

FUEL

USE DIESEL FUEL ONLY
Low Sulphur fuel or ultra low sulphur fuel in USA and
CANADA only.

• Fill the fuel tank with clean, fresh diesel fuel. The
capacity of the fuel tank is approximately

specific fuel recommendations. Running out of
fuel may require bleeding the fuel injection
pump. NOTE: Before starting the engine, open
the fuel shutoff valve (pointer to be in line with
hose).

------------------------------------------------------------------------

ENGINE COOLING SYSTEM

The cooling system has been filled at the factory with a
50-50 mixture of ethylene glycol antifreeze and water.
Check the radiator level and add a 50-50 solution as
needed. (See Engine Manual or antifreeze container for
alternate antifreeze recommendation.)

ENGINE BREAK-IN 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.

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 successful
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.

• Wipe up spilled fuel and allow
fumes to clear before starting
engine.

• Do not overfill tank, fuel
expansion may cause over­flow.

DIESEL FUEL ONLY

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.

1. Connect the welder output studs to a suitable resistive
load bank. Note that any attempt to short the output
studs by connecting 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 generator and voids the warranty.

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.
