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 THAT 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 equipOM-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.
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.
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 exchanged.
3.
Hose
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.
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.
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 connections. 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
Open cylinder valve slowly so that regulator pressure increases 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.
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.

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 outside air. Carbon monoxide can kill.
C. Fire and Explosion Prevention
Comply with precautions in 1-2C.
Equipment’s rated capacity. Do not overload arc welding 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 vessel. 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 as
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.
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.
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.
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 Support 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.

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.
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 an 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.

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 (Figure 6-1)
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
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).

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 STARTING 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.
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
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.

MAINTENANCE-FREE BATTERY CHARGING
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) before 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 clothing, and remove all metal jewelry.
• Do not spill or splash battery fluid.
• Do not apply pressure to walls of filled battery—use battery carrier or place hands on
opposite corners when lifting battery.
• Keep sparks, flames, cigarettes, and other ignition 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 connections to battery.
• Do not lean over battery when charging.
• Be sure battery charger connections to battery are clean and tight.
• Keep vent caps in place and cover top of battery with damp cloth.
• Be sure battery charger output matches battery voltage.
• Turn the battery charger off before disconnecting 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 hydrometer. (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.

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.
BRUSHES AND SLIP RINGS (Figure 8-3)
WARNING: ELECTRIC SHOCK can kill
• Do not touch live electrical parts.
• Stop engine, and disconnect negative (−) battery 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.
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.
1/2 in. (12.7 mm)

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.
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.

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.
8-10. ETHER STARTING AID (Optional)
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
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:
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.
occur during the run-in period if the engine is left at idle
rpm too long, or the welding generator is not heavily
loaded.
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.
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.
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 to
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
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.

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.
