A Only qualified persons should install, operate, maintain, and
repair this unit.
A During operation, keep everybody, especially children, away.
Touching live electrical paris can cause fatal
shocks or severe burns. The electrode and work
circuit is electrically live whenever the output is on.
The input power circuit and machine internal
circuits are also live when power is on. In semiautomatic or
automatic wire welding, the wire, wire reel, drive roll housing, and all
metal parts touching the welding wire are electrically live, Incorrectly
installed or improperly grounded equipment is a hazard.
Do not touch live electrical parts.
Wear dry, hole-free insulating gloves and body protection.
Insulate yourself from work and ground using dry insulating mats
or covers big enough to prevent any physical contact with the
work or ground.
e Donotuse AC outputindampareas, ifmovementis confined, orif
there is a danger of falling.
Use AC output ONLY if required for the welding process.
If AC output is required, use remote output control if present on

e Always verify the supply ground - check and be sure that input
power cord ground wire is properly connected to ground terminal
in disconnect box or that cord plug is connected to a properly
grounded receptacle outlet.
e When making input connections, attach proper grounding
conductor first - double-check connections.
e Frequently inspect input power cord for damage or bare wiring -
replace cord immediately if damaged - bare wiring can kill.
e Turn off all equipment when not in use.
¢ Donotuse worn, damaged, undersized, or poorly spliced cables.
e [Do not drape cables over your body.
.
H earth grounding of the workpiece is required, ground it directly
with a separate cable.
¢ Doncttouch electrode if you are in contact with the work, ground,
or another electrode from a different machine.
e Useonly well-maintained equipment. Repair or replace damaged
parts at once. Maintain unit according to manual.
® Wear a safety harness if working above floor level.
Keep all panels and covers securely in piace.
e Clamp work cable with good metal-to-metal contact to workpiece
or worktable as near the weld as practical.
e [nsulate work clamp when not connected to workpiece to prevent
contact with any metal object.
e Do not connect more than one electrode or work cable to any
single weld output terminal.
SIGNIFICANT DC VOLTAGE exists after stopping
engine on inverters.
e Stop engine oninverter and discharge input capacitors according
to instructions in Maintenance Section before touching any parts.
Arc rays from the welding process produce intense
visible and invisible (ultraviolet and infrared) rays
that can burn eyes and skin. Sparks fly off from the
weld.
e Wear awelding helmet fitted with a proper shade of filter to protect
your face and eyes from arc rays and sparks when welding or
watching (see ANSI Z49.1 and Z87.1 listed in Safety Standards).
e Wear approved safety glasses with side shields under your
helmet.
® Use protective screens or barriers to protect others from flash and
glare; warn others not to watch the are.
® Wear protective clothing made from durable, flame-resistant
material {wool and leather) and foot protection.
Welding produces fumes and gases. Breathing
these fumes and gases can be hazardous to your
health.
e Keep your head out of the fumes, Do not breathe the fumes.
e jf inside, ventilaie the area and/or use exhaust at the arc to
remove welding fumes and gases.
¢ |f ventilation is poor, use an approved air-supplied respirator.
e Read the Material Safety Data Sheets (MSDSs) and the
manufacturers instructions for metals, consumabies, coatings,
cleaners, and degreasers.
e Work in a confined space only if it is well ventilated, or while
wearing an air-supplied respirator. Always have a trained watch-
person nearby. Welding fumes and gases can displace air and
lower the oxygen level causing injury or death. Be sure the
breathing air is safe.
e Do not weld in locations near degreasing, cleaning, or spraying
operations. The heat and rays of the arc can react with vapors to
form highly toxic and irritating gases.
e Do not weld on coated metals, such as galvanized, lead, or
cadmium plated steel, unless the coating is removed from the
weld area, the area is well ventilated, and if necessary, while
wearing an air-suppiied respirator. The coatings and any metals
containing these elements can give off toxic fumes if welded.
OM-477 Page 1
Welding on closed containers, such as tanks,
drums, or pipes, can cause them to blow up. Sparks
can fly off from the welding arc. The flying sparks,
hot workpiece, and hot equipment can cause fires
and burns. Accidental contact of electrode to metal objects can
cause sparks, explosion, overheating, or fire. Check and be surethe
area is safe before doing any welding.
e Protect yourself and others from flying sparks and hot metal.
e Do not weld where flying sparks can strike flammable material.
e Remove all flammables within 35 ft (10.7 m} of the welding arc. If
this is not possible, tightly cover them with approved covers,
e Be alert that welding sparks and hot materials from welding can
easily go through small cracks and openings to adjacent areas.
® Watch for fire, and keep a fire extinguisher nearby.
e Be aware that welding on a ceiling, floor, bulkhead, or partition
can cause fire on the hidden side.
® Do not weld on closed containers such as tanks, drums, or pipes,
unless they are properly prepared according to AWS F4.1 (see
Safety Standards).
e Connect work cable to the work as close to the welding area as
practical to prevent welding current from traveling long, possibly
unknown paths and causing electric shock and fire hazards.
® Do not use welder to thaw frozen pipes.
e Remove stick electrode from holder or cut off welding wire at
contact tip when not in use.
e Wear oil-free protective garments such as leather gloves, heavy
shirt, cuffless trousers, high shoes, and a cap.
¢ Remove any combustibles, such as a butane lighter or matches,
from your person before doing any welding.
Welding, chipping, wire brushing, and grinding
cause sparks and flying metal. As welds cool,
they can throw off slag.
e Wear approved safety glasses with side
shields even under your welding helmet.
Shut off shielding gas suppiy when not in use.
e Always ventilate confined spaces or use ap-
proved air-suppiied respirator.
Stop engine and let it cool off before checking
or adding fuel.
e Do not add fuel while smoking or if unit is near
any sparks or open flames.

Considerations About Welding And The Effects Of Low Frequency
Electric And Magnetic Fields
Welding current, as it flows through welding cables, will cause electro-
magnetic fields. There has been and still is some concern about such
fields. However, after examining more than 500 studies spanning 17
years of research, a special blue ribbon committee of the National
Research Council concluded that: “The body of evidence, in the
committee's judgment, has not demonstrated that exposure to power-
frequency electric and magnetic fields is a human-heaith hazard.”
However, studies are still going forth and évidence continues to be
examined. Until the final conclusions of the research are reached, you
may wish to minimize your exposure to electromagnetic fields when
welding or cutting.
To reduce magnetic fields in the workplace, use the following
procedures:
OM-477 Page 4
1. Keep cabies close together by twisting or taping them.
2. Arrange cables to one side and away from the operator.
3. Do not coil or drape cables around your body.
4. Keep welding power source and cables as far away from
operator as practical.
5. Connect work clamp to workpiece as close to the weld as
possible,
About Pacemakers:
Pacemaker wearers consult your doctor first. If cleared by your doctor,
then following the above procedures is recommended.

Données sur te soudage électrique et sur les effets, pour l'organisme,
des champs magnétiques basse fréquence
Le courant de soudage, pendant son passage dans les câbles de sou-
dage, causera des champs électromagnétiques. I! y a eu et il y a
encore un certain souci à propos de tels champs. Cependant, après
avoir examiné plus de 500 études qui ont été faites pendant une pé-
riode de recherche de 17 ans, un comité spécial ruban bieu du
National Research Council a conclu: “L’accumulation de preuves, sui-
vant le jugement du comité, n’a pas démontré que l'exposition aux
champs magnétiques et champs électriques à haute fréquence repré-
sente un risque à la santé humaine”. Toutefois, des études sont
toujours en cours et les preuves continuent à être examinées. En at-
tendant que les conclusions finales de la recherche soient établies, il
vous serait souhaitable de réduire votre exposition aux champs elec-
tromagnétiques pendant le soudage ou le coupage.
OM-477 Page 8
e L'énergie électromagnétique risque de provoquer
des interférences pour l'équipement électronique
sensible tel que les ordinateurs et l'équipement com-
mandé par ordinateur tel que les robots.
e Veiller à ce que tout l'équipement de ia zone de soudage soit compatible
électromagnétiquement.
e Pour réduire la possibilité d'interférence, maintenir les câbles de souda-
ge aussi courts que possible, les grouper, et les poser aussi bas que pos-
sible (ex. par terre).
e Veiller á souder á une distance de 100 métres de tout equipement élec-
tronique sensible,
e Veiller à ce que ce poste de soudage soit posé et mis & la terre conformé-
ment à ce mode d'emploi.
e En cas d'interférences après avoir pris les mesures précédentes, il in-
combe à l'utilisateur de prendre des mesures supplémentaires telles que
\е déplacement du poste, l’utilisation de câbles blindés, l’utilisation de fil-
tres de ligne ou la pose de protecteurs dans la zone de travail.

[7 This unit has a max OCV control circuit
that resets Amperage/Vvoltage Adjust
Control! R1 to maximum when the arc
breaks. When an arc is struck, weld out-
put controf returns to the R1 front panel or
combination front panelremote control
setting. The Amperage/Voltage Adjust
control adjusts amperage only when
constant current (CC) welding and does
not adjust open-circuit voltage. The тах
OCV control circuit does not function
when constant voltage (CV) welding
(optional).
1 Ampere Range Switch
À Do not switch under load.
Use switch to select weld amperage range.
For most welding applications, use lowest
amperage range possible to help prevent arc
outages. When using MIG (CV) mode (op-
tional}, place switch in maximum position.
2 Amperage/Voltage Adjust Control
Control adjusts amperage within range se-
lected by Ampere Range switch. Weld output
would be 148 A DC with controls set as
shown (50% of 85 to 210 A).
3 Amperage/Voltage Adjust Switch
(Optional)
Use switchto select front panel or remote am-
perage control (see Section 5-3).
For front panel control, place switch in Panel
position. For remote control, place switch in
Remote position and connect remote control
to Remote 14 receptacle RC3 or terminal
strip 3T.
4 Quiput (Electrode) Control Switch
(Optional)
Use switch to control remote contactor con-
nected to receptacle RC3 or terminal strip 3T
(see Sections 4-7 and 4-8).
A Weld output terminals are energized
when Output (Electrode) switch is On
(Hot) and engine is running.
For weld output, place switch in the On (Hot)
position. Open-circuit voltage is present at
the weld output terminals whenever engine is
running.
For remote output control, place switch in Re-
mote position, Open-circuit voltage is present
at the weld output terminals when remote
contactor switch is closed.
3 Process Switch (Optional)
Use switch to select Stick or MIG (CV) weld
output. Use Stick for Stick (SMAW) welding.
Use MIG (CV) for wire feed processes (MIG,
FCAW). If using MIG (CV), place Ampere
Range switch in maximum position. To en-
sure wire feeder reliability and improve
arc starting, unit does not run at idle
speed when operated in MIG (CV) mode.
[5 Place Process switch in Stick position
when using optional auxiliary power
plant.
6 DC Voltmeter (Optional)
7 DC Ammeter (Optional)
8 Magnetic Shutdown Switch
Use switch during start-up to bypass engine
shutdown system. System stops engine if oil
pressure is too low or coolant temperature is
too high.
9 Choke Control
Use choke to change engine air-fuel mix.
10 Engine Control Switch
Use switch to start engine, select engine
speed, and stop engine.
In Run position, engine runs at weld/power
speed. In Run/ldle position, engine runs at
idle speed at no load and weld speed with
load applied. Turn to run position if using op-
tional auxiliary power plant.
To Start: Pull choke out. Turn Engine Control
switch to Start while pressing Shutdown
switch. Release Engine Control switch when
engine starts, then release Shutdown switch
and push choke in.
[5 If the engine does not start, let engine
come to a complete stop before attempt-
ing restart.
To Stop: turn Engine Control switch to Off
position.

AMPERES x VOLTS = WATTS
EXAMPLE 1: Hadrill uses 4.5 amperes at 115 volts, calculate its running power
requirement in watts.
4.5AX115V=520 W
The load applied by the drill is 520 watts.
EXAMPLE 2: Ifthree 200 watt flood lamps are used with the drill from Example 1,
add the individual loads to calculate total load.
(200 W + 200 W + 200 W) + 520 W = 1120 W
The total load applied by the three flood lamps and drilt is 1120 watts.
1 Resistive Load
À light bulb is a resistive load and
requires a constant amount of
power.
2 Non-Resistive Load
Equipment with a motor is a non-
resistive load and requires approx-
imately sixtimes more power while
starting the motor than when run-
ning (see Section 2-8).

To find starting amperage:
Step 1: Find code and use table to
find KVA/HP. If code is not listed,
multiply running amperage by six
to find starting amperage.
Step 2: Find Motor HP and Volts.
Step 3: Determine starting amper-
age (see example).
Welding generator amperage out-
put must be at least twice the

9-9. How Much Power Can Generator Supply?
1 Limit Load To 90% Of
Generator Output
Always start non-resistive (motor)
loads in order from largest to
smallest, and add resistive loads
last.
2 5 Second Rule
if motor does not start within 5
seconds, turn off power to prevent
motor damage. Motor requires
more power than generator can
supply.

QUALITY SYSTEM
Take on tough welding jobs
now and keep your options
open. The Big 40%G's solid-
state circuitry and alternator
deliver smooth welding overits entire range. Even
Options enable Flux Cored, MIG, AC Stick and
non-critical AC TIG. While welding, the Big 40G
provides 3 kW at 120 VAC. For more auxiliary
output alone, the Deluxe Package option offers
12 kW of three-phase power when not welding.
under heavy loads in demanding locations, this
machine furnishes reliable productivity.
Features
Benefits
3-phase, 4-pole revoiving field
technology
Provides efficient welding current with less horsepower than DC generator technology
— less horsepower per welding amp saves fuel — as much as 20 to 30 percent. Easily
connects in paraliel with no special kits for heavy gouging or stud welding applications.
Five welding ranges
Provides overlapping ranges and fine current control in each range for easy set-up
and control of welding amperage.
Wiscon Continental gasoline
engine
Continental engines have been used for decades in Miller's industrial engine-driven
weiders. Engine runs at 1800 rpm for long service life.
Automatic idle
Saves fuel and prolongs engine life. Reduces noise.
Automatic engine shutdown
Recently added as a standard feature. It protects the engine from failure due to tow
oil pressure or high coolant temperature.
Improved fuel tank design
New, fieavier gauge, aluminized steel tank is more resistant to corrosion —
17-1/2 gal (66 L} runs ai! shift before refueling.
New fuel gauge and hour meter
Helps operator monitor fuel [evel and maintenance schedule. Conveniently mounted
on front panel.
Solid-state circuitry
Provides field current regulation to minimize any decrease in output as the machine
heats up— even at rated loads. It also permits factory or field installed CV-3 or
14-pin remote control options to be added.
3 KWAYA auxiliary power while
welding
Auxiliary power available from two 120 VAC duplex receptacles that are circuit
breaker protected. Optional 240 VAC and GFC| receptacles available.
Optional Welder’s Package
Order one package to get all the factory-installed options needed to weld AC Stick and
AC TIG. Includes weld meters, polarity/AC selector switch, and remote control facilities.
Optional Welder's Package with CV
Adds constant voltage CV-3 module to Welder's Package options.
Optional Deluxe Package
Includes all factory options required for MIG and Hux Cored welding: Constant voltage
CV-3 module, weld meters and 12 kW auxiliary power.
