SECTION 1 − SAFETY RULES FOR OPERATION OF ARC WELDING POWER SOURCE

1-1. INTRODUCTION

We learn by experience. Learning safety through per­sonal experience, like a child touching a hot stove is
harmful, wasteful, and unwise. Let the experience of
others teach you.

Safe practices developed from experience in the use of
welding and cutting are described in this manual. Re­search, development, and field experience have
evolved reliable equipment and safe installation, opera­tion, and servicing practices. Accidents occur when
equipment is improperly used or maintained. The rea­son for the safe practices may not always be given.
Some are based on common sense, others may require
technical volumes to explain. It is wiser to follow the
rules.

Read and understand these safe practices before at­tempting to install, operate, or service the equipment.
Comply with these procedures as applicable to the par­ticular equipment used and their instruction manuals,
for personal safety and for the safety of others.

Failure to observe these safe practices may cause seri­ous injury or death. When safety becomes a habit, the
equipment can be used with confidence.

These safe practices are divided into two Sections:
1-General Precautions, common to arc welding and cut­ting; and 2-Arc Welding (and Cutting) (only).

Reference standards: Published Standards on safety
are also available for additional and more complete pro­cedures than those given in this manual. They are listed
in the Standards Index in this manual. ANSI Z49.1 is the
most complete.

The National Electrical Code, Occupational Safety and
Health Administration, local industrial codes, and local
inspection requirements also provide a basis for equip­ment installation, use, and service.

1-2. GENERAL PRECAUTIONS
Different arc welding processes, electrode alloys,

and fluxes can produce different fumes, gases, and
radiation levels. In addition to the information in
this manual, be sure to consult flux and electrode
manufacturers Material Safety Data Sheets
(MSDSs) for specific technical data and precaution­ary measures concerning their material.

A. Burn Prevention

Wear protective clothing-gauntlet gloves designed for
use in welding, hat, and high safety-toe shoes. Button
shirt collar and pocket flaps, and wear cuffless trousers
to avoid entry of sparks and slag.

Wear helmet with safety goggles and glasses with side
shields underneath, appropriate filter lenses or plates
(protected by clear cover glass). This is a MUST for
welding or cutting, (and chipping) to protect the eyes

from radiant energy and flying metal. Replace cover
glass when broken, pitted, or spattered. See 1-3A.2.

Avoid oily or greasy clothing. A spark may ignite them.
Hot metal such as electrode stubs and workpieces

should never be handled without gloves.
Medical first aid and eye treatment. First aid facilities

and a qualified first aid person should be available for
each shift unless medical facilities are close by for im­mediate treatment of flash burns of the eyes and skin
burns.

Ear plugs should be worn when working on overhead or
in a confined space. A hard hat should be worn when
others work overhead.

Flammable hair preparations should not be used by per­sons intending to weld or cut.

B. Toxic Fume Prevention

Severe discomfort, illness or death can result from
fumes, vapors, heat, or oxygen enrichment or depletion
that welding (or cutting) may produce. Prevent them
with adequate ventilation as described in ANSI Stan­dard Z49.1 listed in Standards Index. NEVER ventilate
with oxygen.

Lead -, cadmium -, zinc -, mercury -, and beryllium-bear­ing and similar materials, when welded (or cut) may pro­duce harmful concentrations of toxic fumes. Adequate
local exhaust ventilation must be used, or each person
in the area as well as the operator must wear an air-sup­plied respirator. For beryllium, both must be used.

Metals coated with or containing materials that emit
toxic fumes should not be heated unless coating is re­moved from the work surface, the area is well ventilated
and, if necessary , while wearing an air-supplied respira­tor.

Work in a confined space only while it is being ventilated
and, if necessary , while wearing an air-supplied respira­tor.

Gas leaks in a confined space should be avoided.
Leaked gas in large quantities can change oxygen con­centration dangerously . Do not bring gas cylinders into a
confined space.

Leaving confined space, shut OFF gas supply at source
to prevent possible accumulation of gases in the space if
downstream valves have been accidentally opened or
left open. Check to be sure that the space is safe before
re-entering it.

Vapors from chlorinated solvents can be decomposed
by the heat of the arc (or flame) to form PHOSGENE, a
highly toxic gas, and other lung and eye irritating prod­ucts. The ultraviolet (radiant) energy of the arc can also
decompose trichloroethylene and perchloroethylene
vapors to form phosgene. DO NOT WELD or cut where
solvent vapors can be drawn into the welding or cutting

OM-166 941 Page 1

atmosphere or where the radiant energy can penetrate
to atmospheres containing even minute amounts of
trichloroethylene or perchloroethylene.

C. Fire and Explosion Prevention

Causes of fire and explosion are: combustibles reached
by the arc, flame, flying sparks, hot slag or heated mate­rial; misuse of compressed gases and cylinders; and
short circuits.

BE AWARE THA T flying sparks or falling slag can pass
through cracks, along pipes, through windows or doors,
and through wall or floor openings, out of sight of the
goggled operator. Sparks and slag can fly 35 feet.

To prevent fires and explosion:
Keep equipment clean and operable, free of oil, grease,

and (in electrical parts) of metallic particles that can
cause short circuits.

If combustibles are in area, do NOT weld or cut. Move
the work if practicable, to an area free of combustibles.
Avoid paint spray rooms, dip tanks, storage areas, ven­tilators. If the work cannot be moved, move comb­ustibles at least 35 feet away out of reach of sparks and
heat; or protect against ignition with suitable and snug­fitting, fire-resistant covers or shields.

Walls touching combustibles on opposite sides should
not be welded on (or cut). Walls, ceilings, and floor near
work should be protected by heat-resistant covers or
shields.

Fire watcher must be standing by with suitable fire extin­guishing equipment during and for some time after weld­ing or cutting if:

a. appreciable combustibles (including building

construction) are within 35 feet

b. appreciable combustibles are further than 35

feet but can be ignited by sparks

c. openings (concealed or visible) in floors or walls

within 35 feet may expose combustibles to
sparks

d. combustibles adjacent to walls, ceilings, roofs,

or metal partitions can be ignited by radiant or
conducted heat.

Hot work permit should be obtained before operation to
ensure supervisor’s approval that adequate precau­tions have been taken.

After work is done, check that area is free of sparks,
glowing embers, and flames.

An empty container that held combustibles, or that can
produce flammable or toxic vapors when heated, must
never be welded on or cut, unless container has first
been cleaned as described in AWS Standard A6.0,
listed 7 in Standards Index.

This includes: a thorough steam or caustic cleaning (or
a solvent or water washing, depending on the combusti­ble’s solubility) followed by purging and inerting with ni­trogen or carbon dioxide, and using protective equip-

OM-166 941 Page 2

ment as recommended in A6.0. Waterfilling just below
working level may substitute for inerting.

A container with unknown contents should be cleaned
(see preceding paragraph). Do NOT depend on sense
of smell or sight to determine if it is safe to weld or cut.

Hollow castings or containers must be vented before
welding or cutting. They can explode.

Explosive atmospheres. Never weld or cut where the air
may contain flammable dust, gas, or liquid vapors (such
as gasoline).

D. Compressed Gas Equipment

Standard precautions. Comply with precautions in this
manual, and those detailed in CGA Standard P-1, SAFE
HANDLING OF COMPRESSED GASES IN CYLIN­DERS, listed 11 in Standards Index.

1. Pressure Regulators

Regulator relief valve is designed to protect only the
regulator from overpressure; it is not intended to protect
any downstream equipment. Provide such protection
with one or more relief devices.

Never connect a regulator to a cylinder containing gas
other than that for which the regulator was designed.

Remove faulty regulator from service immediately for
repair (first close cylinder valve). The following symp­toms indicate a faulty regulator:

Leaks-if gas leaks externally.
Excessive Creep-if delivery pressure continues to rise
with downstream valve closed.
Faulty Gauge-if gauge pointer does not move off stop
pin when pressurized, nor returns to stop pin after pres­sure release.

Repair. Do NOT attempt to repair. Send faulty regula­tors for repair to manufacturer’s designated repair cen­ter, where special techniques and tools are used by
trained personnel.

2. Cylinders

Cylinders must be handled carefully to prevent leaks
and damage to their walls, valves, or safety devices:

Avoid electrical circuit contact with cylinders including
third rails, electrical wires, or welding circuits. They can
produce short circuit arcs that may lead to a serious ac­cident. (See 1-3C.)

ICC or DOT marking must be on each cylinder. It is an
assurance of safety when the cylinder is properly han­dled.

Identifying gas content. Use only cylinders with name of
gas marked on them; do not rely on color to identify gas
content. Notify supplier if unmarked. NEVER DEFACE
or alter name, number, or other markings on a cylinder. It
is illegal and hazardous.

Empties: Keep valves closed, replace caps securely;
mark MT; keep them separate from FULLS and return
promptly.

Prohibited use. Never use a cylinder or its contents for
other than its intended use, NEVER as a support or
roller.

Locate or secure cylinders so they cannot be knocked
over.

outlet away from people and sources of ignition. Wipe
with a clean lintless cloth.

Passageways and work areas. Keep cylinders clear of
areas where they may be struck.

Transporting cylinders. With a crane, use a secure sup­port such as a platform or cradle. Do NOT lift cylinders
off the ground by their valves or caps, or by chains,
slings, or magnets.

Do NOT expose cylinders to excessive heat, sparks,
slag, and flame, etc. that may cause rupture. Do not al­low contents to exceed 130°F. Cool with water spray
where such exposure exists.

Protect cylinders particularly valves from bumps, falls,
falling objects, and weather. Replace caps securely
when moving cylinders.

Stuck valve. Do NOT use a hammer or wrench to open a
cylinder valve that can not be opened by hand. Notify
your supplier.

Mixing gases. Never try to mix any gases in a cylinder.
Never refill any cylinder.
Cylinder fittings should never be modified or ex-

changed.

3. Hose

Prohibited use. Never use hose other than that de­signed for the specified gas. A general hose identifica­tion rule is: red for fuel gas, green for oxygen, and black
for inert gases.

Use ferrules or clamps designed for the hose (not ordi­nary wire or other substitute) as a binding to connect
hoses to fittings.

No copper tubing splices. Use only standard brass fit­tings to splice hose.

Match regulator to cylinder. Before connecting, check
that the regulator label and cylinder marking area, and
that the regulator inlet and cylinder outlet match.
NEVER CONNECT a regulator designed for a particular
gas or gases to a cylinder containing any other gas.

Tighten connections. When assembling threaded con­nections, clean and smooth seats where necessary.
Tighten. If connection leaks, disassemble, clean, and
retighten using properly fitting wrench.

Adapters. Use a CGA adapter (available from your sup­plier) between cylinder and regulator, if one is required.
use two wrenches to tighten adapter marked RIGHT
and LEFT HAND threads.

Regulator outlet (or hose) connections may be identified
by right hand threads for oxygen and left hand threads
(with grooved hex on nut or shank) for fuel gas.

5. Pressurizing Steps:

Drain regulator of residual gas through suitable vent be­fore opening cylinder (or manifold valve) by turning ad­justing screw in (clockwise). Draining prevents exces­sive compression heat at high pressure seat by allowing
seat to open on pressurization. Leave adjusting screw
engaged slightly on single-stage regulators.

Stand to side of regulator while opening cylinder valve.
Open cylinder valve slowly so that regulator pressure in-

creases slowly. When gauge is pressurized (gauge
reaches regulator maximum) leave cylinder valve in fol­lowing position: For oxygen, and inert gases, open fully
to seal stem against possible leak. For fuel gas, open to
less than one turn to permit quick emergency shutoff.

Use pressure charts (available from your supplier) for
safe and efficient, recommended pressure settings on
regulators.

Avoid long runs to prevent kinks and abuse. Suspend
hose off ground to keep it from being run over, stepped
on, or otherwise damaged.

Coil excess hose to prevent kinks and tangles.
Protect hose from damage by sharp edges, and by

sparks, slag, and open flame.
Examine hose regularly for leaks, wear, and loose con-

nections. Immerse pressured hose in water; bubbles in­dicate leaks.

Repair leaky or worn hose by cutting area out and splic­ing (1-2D3). Do NOT tape.

4. Proper Connections

Clean cylinder valve outlet of impurities that may clog
orifices and damage seats before connecting regulator.
Except for hydrogen, crack valve momentarily, pointing

Check for leaks on first pressurization and regularly
there-after. Brush with soap solution (capfull of Ivory
Liquid* or equivalent per gallon of water). Bubbles indi­cate leak. Clean off soapy water after test; dried soap is
combustible.

E. User Responsibilities

Remove leaky or defective equipment from service im­mediately for repair . See User Responsibility statement
in equipment manual.

F. Leaving Equipment Unattended

Close gas supply at source and drain gas.

G. Rope Staging-Support

Rope staging-support should not be used for welding or
cutting operation; rope may burn.

1-3. ARC WELDING

Comply with precautions in 1-1, 1-2, and this section.
Arc Welding, properly done, is a safe process, but a
careless operator invites trouble. The equipment carries
high currents at significant voltages. The arc is very
bright and hot. Sparks fly , fumes rise, ultraviolet and in­frared energy radiates, weldments are hot, and com­pressed gases may be used. The wise operator avoids
unnecessary risks and protects himself and others from
accidents. Precautions are described here and in stan­dards referenced in index.

A. Burn Protection

Comply with precautions in 1-2.
The welding arc is intense and visibly bright. Its radiation

can damage eyes, penetrate lightweight clothing, reflect
from light-colored surfaces, and burn the skin and eyes.
Skin burns resemble acute sunburn, those from gas­shielded arcs are more severe and painful. DON’T GET
BURNED; COMPLY WITH PRECAUTIONS.

1. Protective Clothing

Wear long-sleeve clothing (particularly for gas-shielded
arc) in addition to gloves, hat, and shoes (1-2A). As nec­essary, use additional protective clothing such as
leather jacket or sleeves, flame-proof apron, and fire-re­sistant leggings. Avoid outer garments of untreated cot­ton.

Bare skin protection. Wear dark, substantial clothing.
Button collar to protect chest and neck and button pock­ets to prevent entry of sparks.

2. Eye and Head Protection

Protect eyes from exposure to arc. NEVER look at an
electric arc without protection.

Welding helmet or shield containing a filter plate shade
no. 12 or denser must be used when welding. Place over
face before striking arc.

Protect filter plate with a clear cover plate.
Cracked or broken helmet or shield should NOT be

worn; radiation can pass through to cause burns.
Cracked, broken, or loose filter plates must be replaced

IMMEDIATELY. Replace clear cover plate when broken,
pitted, or spattered.

Flash goggles with side shields MUST be worn under
the helmet to give some protection to the eyes should
the helmet not be lowered over the face before an arc is
struck. Looking at an arc momentarily with unprotected
eyes (particularly a high intensity gas-shielded arc) can
cause a retinal burn that may leave a permanent dark
area in the field of vision.

3. Protection of Nearby Personnel

Enclosed welding area. For production welding, a sepa­rate room or enclosed bay is best. In open areas, sur­round the operation with low-reflective, non-combusti­ble screens or panels. Allow for free air circulation, par­ticularly at floor level.

OM-166 941 Page 4

Viewing the weld. Provide face shields for all persons
who will be looking directly at the weld.

Others working in area. See that all persons are wearing
flash goggles.

Before starting to weld, make sure that screen flaps or
bay doors are closed.

B. Toxic Fume Prevention

Comply with precautions in 1-2B.
Generator engine exhaust must be vented to the out-

side air. Carbon monoxide can kill.

C. Fire and Explosion Prevention

Comply with precautions in 1-2C.
Equipment’s rated capacity. Do not overload arc weld-

ing equipment. It may overheat cables and cause a fire.
Loose cable connections may overheat or flash and

cause a fire.
Never strike an arc on a cylinder or other pressure ves-

sel. It creates a brittle area that can cause a violent rup­ture or lead to such a rupture under rough handling.

D. Compressed Gas Equipment

Comply with precautions in 1-2D.

E. Shock Prevention

Exposed hot conductors or other bare metal in the weld­ing circuit, or in ungrounded, electrically-HOT equip­ment can fatally shock a person whose body becomes a
conductor. DO NOT STAND, SIT, LIE, LEAN ON, OR
TOUCH a wet surface when welding, without suitable
protection.

To protect against shock:
Wear dry insulating gloves and body protection. Keep

body and clothing dry. Never work in damp area without
adequate insulation against electrical shock. Stay on a
dry duckboard, or rubber mat when dampness or sweat
can not be avoided. Sweat, sea water, or moisture be­tween body and an electrically HOT part or grounded
metal reduces the electrical resistance, and could en­able dangerous and possibly lethal currents to flow
through the body.

A voltage will exist between the electrode and any con­ducting object in the work circuit. Examples of conduct­ing objects include, but are not limited to, buildings, elec­trical tools, work benches, welding power source cases,
workpieces, etc. Never touch the electrode and any

metal object unless the welding power source is
off.

1. Grounding the Equipment

Arc welding equipment must be grounded according to
the National Electrical Code, and the work must be
grounded according to ANSI Z49.1 “Safety In Welding
And Cutting.”

When installing, connect the frames of each unit such a s
welding power source, control, work table, and water cir­culator to the building ground. Conductors must be ade-

quate to carry ground currents safely. Equipment made
electrically HOT by stray current may shock, possibly
fatally. Do NOT GROUND to electrical conduit, or to a
pipe carrying ANY gas or flammable liquid such as oil or
fuel.

Three-phase connection. Check phase requirements of
equipment before installing. If only 3-phase power is
available, connect single-phase equipment to only two
wires of the 3-phase line. Do NOT connect the equip­ment ground lead to the third (live) wire, or the equip­ment will become electrically HOT-a dangerous condi­tion that can shock, possibly fatally.

Before welding, check ground for continuity. Be sure
conductors are touching bare metal of equipment
frames at connections.

If a line cord with a ground lead is provided with the
equipment for connection to a switchbox, connect the
ground lead to the grounded switchbox. If a three-prong
plug is added for connection to a grounded mating re­ceptacle, the ground lead must be connected to the
ground prong only. If the line cord comes with a three­prong plug, connect to a grounded mating receptacle.
Never remove the ground prong from a plug, or use a
plug with a broken off ground prong.

2. Electrode Holders

Fully insulated electrode holders should be used. Do
NOT use holders with protruding screws.

3. Connectors

Fully insulated lock-type connectors should be used to
join welding cable lengths.

4. Cables

Frequently inspect cables for wear , cracks and damage.
IMMEDIATELY REPLACE those with excessively worn
or damaged insulation to avoid possibly-lethal shock
from bared cable. Cables with damaged areas may be
taped to give resistance equivalent to original cable.

Keep cable dry, free of oil and grease, and protected
from hot metal and sparks.

5. Terminals And Other Exposed Parts

Terminals and other exposed parts of electrical units
should have insulating covers secured before opera­tion.

6. Electrode
a. Equipment with output on/off control (contac-

tor)
Welding power sources for use with the gas

metal arc welding (GMAW), gas tungsten arc
welding (GTAW) and similar processes nor­mally are equipped with devices that permit on­off control of the welding power output. When
so equipped the electrode wire becomes elec­trically HOT when the power source switch is
ON and the welding gun switch is closed. Never
touch the electrode wire or any conducting ob-

ject in contact with the electrode circuit unless
the welding power source is off.

b. Equipment without output on/off control (no

contactor)
Welding power sources used with shielded

metal arc welding (SMAW) and similar proc­esses may not be equipped with welding power
output on-off control devices. With such equip­ment the electrode is electrically HOT when the
power switch is turned ON. Never touch the
electrode unless the welding power source is
off.

7. Safety Devices

Safety devices such as interlocks and circuit breakers
should not be disconnected or shunted out.

Before installation, inspection, or service, of equipment,
shut OFF all power and remove line fuses (or lock or
red-tag switches) to prevent accidental turning ON of
power. Disconnect all cables from welding power
source, and pull all 115 volts line-cord plugs.

Do not open power circuit or change polarity while weld­ing. If, in an emergency , it must be disconnected, guard
against shock burns, or flash from switch arcing.

Leaving equipment unattended. Always shut OFF and
disconnect all power to equipment.

Power disconnect switch must be available near the
welding power source.

F. Protection For Wearers of Electronic Life Sup-

port Devices (Pacemakers)

Magnetic fields from high currents can affect pacemak­er operation. Persons wearing electronic life support
equipment (pacemaker) should consult with their doctor
before going near arc welding, gouging, or spot welding
operations.

OM-166 941 Page 9

4-4. FUEL

WARNING: REMOVE FUEL CAP SLOWLY;
FUEL SPRAY may cause injury; FUEL may
be under pressure.

• Rotate fuel cap slowly and wait until hissing

stops before removing cap.

ENGINE FUEL can cause fire or explosion.

• Stop engine before checking or adding fuel.

• Do not spill fuel; if spilled, wipe up.

• Do not refuel if engine is hot or running.

• Do not refuel near sparks or open flame.

• Do not smoke while refueling.

• Do not fill fuel tank to top; allow 1/2 in. (13

mm) from fuel to tank top for expansion.

• Do not weld on fuel tank.

IMPORTANT: Fill fuel tank up to 1/2 in. (13 mm) from
top with fresh fuel before starting engine the first time.
Rust and corrosion preventative was added to inside of
fuel tank and engine at the factory and could cause
rough engine running if not properly diluted with a full
tank of fresh fuel.

The capacity of the fuel tank is 30 gallons U.S. Measure
(114 liters). See the Engine Manufacturer’s Manual for
fuel recommendations. Chart 4-1 illustrates typical fuel
consumption under specific load conditions. Fuel con­sumption varies from one engine to another. Different
brands of fuel, operating conditions, condition of the en­gine, etc., also affect the fuel consumption level.

Keep the fuel tank filled to ensure that the injector sys­tem receives an adequate supply of fuel. The fuel cap is
located on the lower front panel, behind the right access
door (see Figure 4-2). If the fuel tank is allowed to empty,
air will enter the system, causing starting problems. The
Engine Manufacturer’s Manual outlines procedures for
air bleeding the fuel system.

4-5. LUBRICATION (Figure 4-2)
A. Oil And Oil Level Indicator

The engine is shipped with its crankcase filled with SAE
20 break-in oil. An oil level indicator is provided on the

Chart 4-1. Fuel Consumption Curve

lower front panel of this unit (see Figure 4-2). If oil level is
below the lower pointer when engine is running, add oil
according to the recommendations in the Engine Man­ufacturer’s Manual (F4L-912 engine). The oil cap is lo­cated under the access door on the top cover.

IMPORTANT : This engine is equipped with a n Oil Pres­sure Shutdown gauge/switch and an Oil Temperature
Shutdown gauge/switch. If oil pressure becomes too
low or oil temperature rises to a level that may cause en­gine damage, the respective gauge/switch shuts down
the engine. The shutdown oil pressure has been factory
set at 30 psi (207 kPa), and the shutdown oil tempera­ture has been set at 265°F (130°C).

B. Wetstacking Considerations

Wetstacking is an accumulation of unburned fuel and oil
in the exhaust pipe. The engine may use oil and wet­stacking may occur during the run-in period if the piston
rings are not seated properly. If oil consumption and
wetstacking occur during run-in period, see Section
8-12.

4-6. EQUIPMENT GROUNDING TERMINAL

GROUND

This unit is equipped with a grounding terminal for
grounding the generator case. The grounding terminal
is located on the lower front panel (see Figure 4-2).
Since the generator neutral is connected to the frame,
the equipment grounding terminal must be connected to
a proper earth ground. Additionally, comply with all na­tional, regional, and local codes concerning portable
generators for the specific application.

For detailed grounding instructions consult your na­tional, regional, and local codes. If additional informa­tion regarding your operating circumstances and/or
grounding requirements is needed, consult a qualified
electrician or your dealer. After determining the extent to
which any grounding requirements apply to your par­ticular situation, follow them explicitly.

4-7. WELD OUTPUT CONNECTIONS (Table 4-1

And Figure 4-2)

RATED WELD OUTPUT

To obtain full rated output from this unit, it is necessary to
select, prepare, and install proper weld cables. Failure
to comply in any of these areas may result in
unsatisfactory welding performance.

A. Weld Cable Selection

B. Weld Cable Preparation

1. Install electrode holder to cable following man­ufacturer’s instructions. Always use an insulated
electrode holder to ensure operator safety.

2. Install correct size lugs onto ends of both cables
for connecting to work clamp, electrode holder or
wire feeder, and weld output terminals.

3. Install work clamp onto cable.

C. Weld Output Connections

Use the following guidelines to select weld cables:

1. Use the shortest possible cables, and place
cables close together. Excessive cable lengths
may reduce output or cause unit overload due to
added resistance.

WARNING: ELECTRIC SHOCK can kill.

• Do not touch live electrical parts.

• Do not touch the output terminals when the

contactor is energized.

• Do not touch welding wire or electrode and

work clamp at same time.

When the OUTPUT/CONTACTOR switch is in
the ON position, open-circuit voltage is present
at the weld output terminals for as long as the
engine is running.

If the OUTPUT(CONTACTOR) switch is in the ON posi­tion, open-circuit voltage will be present at the output
terminals whenever the engine is running.
If remote contactor control by means of a wire feeder or
remote device is desired, make connections to the RE­MOTE 9 receptacle or terminal strip 3T according to
Section 4-8, and place the OUTPUT(CONTACTOR)
switch in the REMOTE position. Open-circuit voltage is
present at the weld output terminals whenever the gun
switch or remote device is closed.

WARNING: ELECTRIC SHOCK can kill.

• Do not touch live electrical parts.

• Do not touch the output terminals when the

contactor is energized

• Do not touch welding wire or electrode and

work clamp at same time.

If remote amperage or voltage control is desired, make
connections to the REMOTE 9 receptacle terminal strip
according to Section 4-8, and place the AMPERAGE &
VOLTAGE switch in the REMOTE position. When a Re­mote Amperage or Voltage Control is being used, the re­mote control functions as a fine amperage or voltage ad­justment for the AMPERAGE & VOLTAGE ADJUST­MENT control on the welding generator. For example, if
the AMPERAGE & VOLTAGE ADJUSTMENT control
on the welding generator is set at midrange, the Remote
Amperage or Voltage Control will provide (from mini­mum to maximum adjustment) fine amperage or voltage
adjustment of one half of the welding generator output
for the range selected. For complete remote control of
the output, rotate the AMPERAGE & VOLTAGE AD­JUSTMENT control to the maximum position.

6-6. SERVICE ENGINE AIR CLEANER LIGHT

FUEL

The FUEL Gauge indicates the level of fuel remaining in
the fuel tank. The unit is equipped with a 30 gallon (114
L) fuel tank.

6-10. MAGNETIC SHUTDOWN SWITCH

An internal switch automatically shuts down the engine
if oil pressure drops to an unsafe level or oil temperature
becomes too high.

The switch assembly is located directly behind the up­per front panel access door, in the upper left corner. The
switch is protected by a fuse located on the bottom of the
switch assembly. Should this fuse open, the engine
would not start. See Section 9-3 for fuse replacement
procedure.

6-11. OIL TEMPERATURE GAUGE/SWITCH (Fig-

ure 6-1)

BATTERY

The BATTERY voltmeter registers the alternator­supplied output voltage to the battery. The meter should
always register 12-15 volts dc while the engine is run­ning. If the voltage is outside this range, stop the engine,
and determine the cause. Do not operate the engine un­til the trouble has been corrected.

6-14. METERS (Figure 6-1)

The meters are provided to monitor the welding opera­tion; however, they are not intended for exact amperage
or voltage measurements. These meters are internally
connected to the output circuit.

The voltmeter indicates the voltage at the weld termi­nals, but not necessarily the actual voltage at the weld­ing arc (due to cable resistance, poor connections, etc.).
The ammeter indicates the amperage output of the unit.

6-15. BROKEN COOLING BELT SHUTDOWN

SWITCH

The OIL TEMPERATURE gauge/switch registers the
temperature of the oil in the lubricating system. If the oil
temperature rises to a level that may cause engine dam­age (factory set at 265°F, 130°C), switch closes and
magnetic shutdown switch stops the engine (see Sec­tion 6-10).

6-12. OIL PRESSURE GAUGE/SWITCH (Figure

6-1)

The OIL PRESSURE gauge/switch registers the lubri­cating system pressure in pounds per square inch (psi).
The pressure registered by the gauge should remain
constant for a given engine speed. Should the pressure
fluctuate or drop, stop the engine, and do not operate
until the trouble has been corrected. If the oil pressure
drops to a level that may cause engine damage, switch
closes and magnetic shutdown switch stops the engine
(see Section 6-10). The shutdown oil pressure is factory
set at 30 psi (207 kPa). Normal operating pressure is ap­proximately 50 psi (345 kPa).

OM-166 941 Page 18

An internal switch automatically shuts down the engine
if the cooling belt breaks. The cooling belt is located on
the rear of the engine. If the engine shuts down, check
for broken cooling belt.

6-16. ETHER STARTING AID (Optional)

The cold weather starting components provide a means
of applying a premeasured portion of ether into the man­ifold. The amount of ether supplied should be sufficient
to permit easy engine starting under cold weather condi­tions.

Depressing ETHER ST AR TING AID switch for one sec­ond while cranking the engine will provide the proper
amount of ether to the manifold. This control will function
only while cranking the engine.

CAUTION: ETHER INJECTION WHILE EN­GINE IS RUNNING can cause engine dam­age.

• Do not actuate ETHER STARTING AID while

engine is running.

IMPORTANT: Ether is sprayed into the engine when
this switch is released. Depressing the switch does not
spray the ether into the engine but rather fills the valve
chamber.

8-6. MAINTENANCE-FREE BATTERY CHARG-

ING

WARNING: CHARGING A FROZEN BAT­TERY can cause the battery to explode and
result in serious personal injury or damage
to equipment.

• Allow battery to warm up to 60° F (16°C) be-

fore charging if battery is frozen.

BATTERY ACID can burn eyes and skin and
destroy clothing and other materials; BAT­TERY GASES can explode and shatter bat­tery.

• Wear a face shield, proper protective cloth-

ing, and remove all metal jewelry.

• Do not spill or splash battery fluid.

• Do not apply pressure to walls of filled bat-

tery—use battery carrier or place hands on
opposite corners when lifting battery.

• Keep sparks, flames, cigarettes, and other ig-

nition sources away from batteries.

• Use enough ventilation to keep battery gases

from building up during and for several hours
after battery charging.

• Do not touch or move connections on battery

while battery charger is on.

• Turn battery charger off before making con-

nections to battery.

• Do not lean over battery when charging.

• Be sure battery charger connections to bat-

tery are clean and tight.

• Keep vent caps in place and cover top of bat-

tery with damp cloth.

• Be sure battery charger output matches bat-

tery voltage.

• Turn the battery charger off before discon-

necting the charger from the battery.

1. Remove battery from unit, and place on a level
worktable or other suitable surface.

2. If battery has removable vent caps, check the
condition of the electrolyte as follows:

a. Check electrolyte temperature in one of the

center cells with a battery thermometer. For
each 10°F (6°C) increment above 80°F (27°C),
a correction factor of 0.004 specific gravity
must be added to the specific gravity reading
taken in Step 2b. For each 10°F (6°C) incre­ment below 80°F (27°C), 0.004 must be sub­tracted from the reading taken in Step 2b.

b. Check the specific gravity of each cell with a hy-

drometer. (Draw in and expel the electrolyte two
or three times from the first cell to be tested to
adjust the temperature of the hydrometer to
that of the electrolyte.)

c. If a corrected specific gravity reading of 1.225 at

80°F (27°C) is not obtained, replace the vent
caps and recharge the battery following the bat­tery charger manufacturer’s instructions.

3. If the battery does not have removable vent caps,
check the condition of the battery as follows:

a. Check the stabilized open−circuit voltage of the

battery. For a 12 volt battery, any reading below

12.4 volts indicates the battery needs charging.
Disconnect both battery cables from the bat­tery, and allow battery voltage to stabilize for
several hours.

b. If the stabilized open−circuit voltage is below

12.4 volts, charge the battery following the bat­tery charger manufacturer’s instructions.

4. Remove damp cloth from battery.

5. Reinstall battery in unit.

6. Replace battery holddown, and tighten securely.
Do not overtighten.

7. Connect positive (+) battery cable to positive (+)
battery terminal.

8. Connect negative (−) battery cable to negative
(−) battery terminal.

the engine, check the speeds with a tachometer. With
no load applied, the weld/power speed should be 1860
rpm. If necessary, adjust the speeds as follows:

1. Open and secure right rear side door.

2. Loosen nut on end of engine speed adjusting
screw (see Figure 8-2).

3. Start the engine as instructed in Section 7-6.

4. Adjust the weld/power speed as follows:

IMPORTANT: All directions, such as clockwise and
counterclockwise, are with respect to the operator fac­ing the rear panel of the unit.

a. To increase weld/power speed, rotate the en-

gine speed adjustment screw clockwise.

b. To decrease weld/power speed, rotate the en-

gine adjustment screw counterclockwise.

OM-166 941 Page 27

5. When the weld/power speed reaches 1860 rpm,
prevent the adjustment screw from turning, and
tighten the securing nut.

7. Close and secure side door.

8-9. BRUSHES AND SLIP RINGS (Figure 8-3)

WARNING: ELECTRIC SHOCK can kill

• Do not touch live electrical parts.

• Stop engine, and disconnect negative (−) bat-

tery cable from battery before inspecting,
maintaining, or servicing.

MOVING PARTS can cause serious injury.

• Keep away from moving parts such as fans,

belts, and rotors.

HOT ENGINE PARTS can cause severe
burns.

• Wear protective gloves and clothing when

working on a hot engine.

No indicator is provided to show the amount of ether left
in the cylinder; therefore, it is recommended that a spare
cylinder be kept on hand. Generally, the ether cylinder is
empty if the engine fails to start in cold weather while uti­lizing the cold weather starting system.

WARNING: IMPROPER HANDLING OR EX­POSURE TO ETHER can seriously harm
your health.

• Follow the manufacturer’s safety instructions

on the cylinder when handling ether compo­nents.

The cylinder can be weighed to determine the amount
of ether inside. The cylinder weighs 33 ounces (936 gr)
when full, and it weighs 15 ounces (425 gr) when empty.
To replace the ether cylinder, see Section 4-10.

IMPORTANT: Before installing the ether cylinder, clean
nozzle on ether cylinder and fitting into which the ether
cylinder is inserted. If dirt is present in either of these ar­eas, the system may not work.

Brush life is very good under most operating conditions.
The brushes and slip rings should be inspected every
six months or whenever excitation voltage is lost. Be
sure that slip rings are clean and brushes are free to
move. If the welding generator has been operating un­der extremely dusty or dirty conditions, increase the fre­quency of inspection.

Under normal use, the slip rings will discolor to a dark
brown. If a buildup of brush material is noted, it may be
necessary to clean the slip rings. Clean rings with a
number 220 or finer sandpaper, and polish rings with
crocus cloth. Never use emery cloth because part of the
emery will embed itself into the rings and, in turn, de­stroy the carbon brushes.

Replace the brushes if they become chipped or broken
or if less than 1/2 in. (12.7 mm) of brush material is left.

CAUTION: ETHER INJECTION WHILE
ENGINE IS RUNNING can cause engine
damage.

• Do not actuate ETHER STARTING AID while

engine is running.

The ether used in the cold weather starting aid system is
contained in a replaceable cylinder located behind the
right rear side door on the center portion of the frame.

OM-166 941 Page 28

IMPORTANT: After installing or replacing ether cylin­der, do not use or test ether start system for at least 10 to
15 minutes to allow particles in fuel to settle to prevent
atomizer plugging.

8-11. SPARK ARRESTOR

WARNING: ELECTRIC SHOCK can kill.

• Do not touch live electrical parts.

• Stop engine and disconnect negative (−)

battery cable from battery before beginning
this installation.

MOVING PARTS can cause severe injury.

• Keep away from moving parts such as fans,

belts, and rotors.

ENGINE EXHAUST SPARKS can cause fire.

• Exhaust spark arrestor must be installed in

accordance with local, state, and federal
regulations.

• Stop engine before cleaning spark arrestor.

• Clean spark arrestor in a noncombustible

environment.

HOT PARTS can cause severe burns.

• The exhaust system must be cold when

servicing the spark arrestor.

Internal combustion engines operating in a highly com­bustible environment are a common fire hazard. Glow­ing carbon particles blown out with the exhaust can re­tain sufficient heat to ignite materials. While no practical
spark arresting device will stop all sparks, this device will
minimize fire hazards by removing and trapping most
solid particles provided that is is properly maintained.

Inspect and service spark arrestor every 250 operation
hours.

Removal of the device from the exhaust system is not
necessary for servicing. Proceed as follows to service
spark arrestor:

occur during the run-in period if the engine is left at idle
rpm too long, or the welding generator is not heavily
loaded.

1. Stop the engine, and allow the exhaust system to
cool.

2. Remove the cleanout plug from the bottom of the
spark arrestor. If a crust has formed over the
hole, break it loose with a screwdriver or similar
tool.

3. Start the engine, and run it at idle rpm to blow col­lected particles out the cleanout hole. If particles
are slow to discharge, momentarily cover the end
of the exhaust stack.

4. Stop the engine, and allow the exhaust system to
cool.

5. Replace and secure the cleanout plug.

8-12. RUN-IN PROCEDURE

WARNING: ELECTRIC SHOCK can kill.

• Do not touch live electrical parts.

• Stop engine before inspecting, connecting,

or servicing.

• Do not leave live unit unattended when

engine is running.

• Keep all panels, covers, and guards

securely in place while engine is running.

MOVING PARTS can cause severe injury.

• Keep away from moving parts such as fans,

belts, and rotors.

HOT ENGINE PARTS can cause severe
burns.

• Wear protective gloves and clothing when

working on hot engine parts or components.

If wetstacking occurs, complete one of the following pro­cedures to dry the engine (see engine Owner’s Manual,
F4L-912 diesel engine). A resistance load is required to
fully load the generator during the run-in procedure. A
load bank or resistance grid may provide a constant load
for run-in, however, a load bank is preferred. If a load
bank is available, proceed with the run-in procedure pro­vided in Subsection A. If a resistance grid is being used,
proceed to Subsection B.

A. Run-In Procedure Using Load Bank (Diagram

8-1)

WARNING: Read and follow safety infor­mation at beginning of entire Section 8-12
before proceeding.

1. Stop engine.

IMPORTANT : Weld cables supplied with load bank may
be inadequate for run-in procedure. Use weld cables of
proper size with appropriate connectors to connect load
bank to generator (see load bank Owner’s Manual).

2. Connect cables from load bank to generator weld
output terminals observing correct polarity (see
Diagram 8-1).

3. Place all load switches in the OFF position.

IMPORTANT: If load bank requires 115 volts ac, it may
be connected to the welding generator auxiliary power
terminal strip, if applicable.

4. Place welding generator AMPERAGE & VOLT­AGE ADJUSTMENT control in the minimum po­sition.

CAUTION: LOW OIL LEVEL can damage
engine; ENGINE MAY USE OIL AND WETS­TACKING may occur during run-in period.

• Check oil level several times a day during

run-in period, and add oil if required.

• See engine Owner’s Manual (Deutz

F4L-912 diesel engine) for run-in informa­tion.

• Do not idle engine longer than necessary

during run-in period.

• Piston rings seat faster if engine runs at

weld/power rpm, and the welding generator
is kept loaded during the run-in period.

The run-in procedure for diesel engines is different than
those associated with gasoline engines. Diesel engines
must be run at near-rated load during the run-in period t o
ensure proper seating of piston rings and to prevent
wetstacking. Wetstacking is an accumulation of un­burned fuel and oil in the exhaust pipe. Wetstacking can

5. Start engine as instructed in Section 7-6, and al­low engine to warm up for approximately three
minutes.

6. Adjust load bank switches and generator controls
to provide a load equal to rated generator output.

For example, if rated generator output is 350 am­peres, 40 volts at 100% duty cycle, adjust
switches until values indicated by load meters
equal rated generator output.

7. Allow engine to run under load for at least one
hour. Check engine and load bank meters after
the first five minutes and every 15 minutes there­after to be sure equipment is operating properly.

8. After running engine under load for at least one
hour, remove load by shutting down load bank.

9. Allow engine to idle for approximately three min­utes to permit internal engine temperatures to
equalize.

12. Inspect inside of exhaust pipe. If pipe is dry, the
run-in procedure is complete. If pipe is coated
with a wet, black, tar-like substance, repeat run­in procedure.

B. Run-In Procedure Using Resistance Grid (Dia-

gram 8-2)

WARNING: Read and follow safety infor­mation at beginning of entire Section 8-12
before proceeding.

1. Stop engine.

2. Obtain resistance grid adequately sized for rated
output of welding generator.

3. Obtain two weld cables of proper size to connect
resistance grid to generator (see Section 4-7).

4. If a voltmeter and ammeter are not provided on
the welding generator, obtain a voltmeter and
clamp-on dc ammeter.

5. Place welding generator AMPERAGE & VOLT­AGE ADJUSTMENT control in the minimum po­sition.

6. Adjust grid switches and generator controls to
provide a load approximately equal to rated gen­erator output.

For example, if rated generator output is 350 am­peres, 40 volts at 100% duty cycle, adjust
switches until values indicated by meters equals
rated generator output.

7. Connect one weld cable to grid input receptacle
and remaining weld cable to grid output recep­tacle (see Diagram 8-2).

8. If a voltmeter and ammeter are provided on the
welding generator, proceed to Step 9. If meters

are not provided, connect voltmeter and clamp­on dc ammeter as shown in Diagram 8-2.

9. Connect remaining ends of weld cables to gener­ator weld output terminals (polarity is not impor­tant).

10. Start engine as instructed in Section 7-6, and al­low engine to warm up for approximately three
minutes.

CAUTION: ARCING can damage switch
contacts.

• Do not change the position of the grid

switches while engine is running.

Arcing causes the contacts to become pitted
and eventually inoperative.

11. Check meters. Adjust load with generator con­trols or, if necessary, by changing positions of grid
switches until values indicated by meters equal
rated generator output.

12. Allow engine to run under load for at least one
hour. Check engine and meters after the first five
minutes and every 15 minutes thereafter to be
sure equipment is operating properly

13. After running engine under load for at least one
hour, remove load by shutting down resistance
grid.

14. Allow engine to idle for approximately three min­utes to permit internal engine temperatures to
equalize.

15. Stop engine, and disconnect weld cables.

16. Allow exhaust system to cool.

17. Inspect inside of exhaust pipe. If pipe is dry, the
run-in procedure is complete. If pipe is coated
with a wet, black, tar-like substance, repeat run­in procedure.
