Thank you and congratulations on choosing Miller. Now you can get the

job done and get it done right. We know you don’t have time to do it any

other way.

That’s why when Niels Miller first started building arc welders in 1929,

he made sure his products offered long-lasting value and superior quality.

Like you, his customers couldn’t afford anything less. Miller products had

to be more than the best they could be. They had to be the best you could

buy.

Today, the people that build and sell Miller products continue the

tradition. They’re just as committed to providing equipment and service

that meets the high standards of quality and value established in 1929.

This Owner’s Manual is designed to help you get the most out of your

Miller products. Please take time to read the Safety precautions. They will

help you protect yourself against potential hazards on the worksite. We’ve

made installation and operation quick and easy. With Miller you can

count on years of reliable service with proper maintenance. And if for

some reason the unit needs repair, there’s a Troubleshooting section that

will help you figure out what the problem is. The parts list will then help

you to decide which exact part you may need to fix the problem.

Warranty and service information for your particular model are also

provided.

Miller Electric manufactures a full line of

welders and welding related equipment. For

1-2. Arc Welding Hazards

The symbols shown below are used throughout this manual

to call attention to and identify possible hazards. When you

see the symbol, watch out, and follow the related instructions

to avoid the hazard. The safety information given below is

only a summary of the more complete safety information

found in the Safety Standards listed in Section 1-5. Read and

follow all Safety Standards.

Only qualified persons should install, operate, maintain, and

repair this unit.

During operation, keep everybody, especially children, away.

ELECTRIC SHOCK can kill.

Touching live electrical parts 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.

D Do not touch live electrical parts.

D Wear dry, hole-free insulating gloves and body protection.

D Insulate yourself from work and ground using dry insulating mats

or covers big enough to prevent any physical contact with the work

or ground.

D Do not use AC output in damp areas, if movement is confined, or if

there is a danger of falling.

D Use AC output ONLY if required for the welding process.

D If AC output is required, use remote output control if present on

unit.

D Additional safety precautions are required when any of the follow-

ing electrically hazardous conditions are present: in damp

locations or while wearing wet clothing; on metal structures such

as floors, gratings, or scaffolds; when in cramped positions such

as sitting, kneeling, or lying; or when there is a high risk of unavoid-

able or accidental contact with the workpiece or ground. For these

conditions, use the following equipment in order presented: 1) a

semiautomatic DC constant voltage (wire) welder, 2) a DC manual

(stick) welder, or 3) an AC welder with reduced open-circuit volt-

age. In most situations, use of a DC, constant voltage wire welder

is recommended. And, do not work alone!

D Disconnect input power or stop engine before installing or

servicing this equipment. Lockout/tagout input power according to

OSHA 29 CFR 1910.147 (see Safety Standards).

D Properly install and ground this equipment according to its

Owner’s Manual and national, state, and local codes.

D 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.

D When making input connections, attach proper grounding conduc-

tor first − double-check connections.

D Keep cords dry, free of oil and grease, and protected from hot metal

and sparks.

D Frequently inspect input power cord for damage or bare wiring −

replace cord immediately if damaged − bare wiring can kill.

D Turn off all equipment when not in use.

D Do not use worn, damaged, undersized, or poorly spliced cables.

D Do not drape cables over your body.

D If earth grounding of the workpiece is required, ground it directly

with a separate cable.

D Do not touch electrode if you are in contact with the work, ground,

or another electrode from a different machine.

D Do not touch electrode holders connected to two welding ma-

chines at the same time since double open-circuit voltage will be

present.

D Use only well-maintained equipment. Repair or replace damaged

parts at once. Maintain unit according to manual.

D Wear a safety harness if working above floor level.

D Keep all panels and covers securely in place.

D Clamp work cable with good metal-to-metal contact to workpiece

or worktable as near the weld as practical.

D Insulate work clamp when not connected to workpiece to prevent

contact with any metal object.

D Do not connect more than one electrode or work cable to any

single weld output terminal.

SIGNIFICANT DC VOLTAGE exists in inverter weld-

ing power sources AFTER removal of inputpower.

D Turn Off inverter, disconnect input power, and discharge input

capacitors according to instructions in Maintenance Section

before touching any parts.

HOT PARTS can burn.

D Do not touch hot parts bare handed.

D Allow cooling period before working on equip-

ment.

D To handle hot parts, use proper tools and/or

wear heavy, insulated welding gloves and

clothing to prevent burns.

OM-235 241 Page 2

Welding produces fumes and gases. Breathing

these fumes and gases can be hazardous to your

health.

FUMES AND GASES can be hazardous.

D Keep your head out of the fumes. Do not breathe the fumes.

D If inside, ventilate the area and/or use local forced ventilation at the

arc to remove welding fumes and gases.

D If ventilation is poor, wear an approved air-supplied respirator.

D Read and understand the Material Safety Data Sheets (MSDSs)

and the manufacturer’s instructions for metals, consumables,

coatings, cleaners, and degreasers.

D 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 breath-

ing air is safe.

D Do not weld in locations near degreasing, cleaning, or spraying op-

erations. The heat and rays of the arc can react with vapors to form

highly toxic and irritating gases.

D 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 while wearing an air-supplied

respirator. The coatings and any metals containing these elements

can give off toxic fumes if welded.

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.

D Wear an approved welding helmet fitted with a proper shade of

filter lenses 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).

D Wear approved safety glasses with side shields under your

helmet.

D Use protective screens or barriers to protect others from flash,

glare and sparks; warn others not to watch the arc.

D Wear protective clothing made from durable, flame-resistant

material (leather, heavy cotton, or wool) and foot protection.

ARC RAYS can burn eyes and skin.

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 sure the area is

safe before doing any welding.

WELDING can cause fire or explosion.

D Remove all flammables within 35 ft (10.7 m) of the welding arc. If

this is not possible, tightly cover them with approved covers.

D Do not weld where flying sparks can strike flammable material.

D Protect yourself and others from flying sparks and hot metal.

D Be alert that welding sparks and hot materials from welding can

easily go through small cracks and openings to adjacent areas.

D Watch for fire, and keep a fire extinguisher nearby.

D Be aware that welding on a ceiling, floor, bulkhead, or partition can

cause fire on the hidden side.

D 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).

D Do not weld where the atmosphere may contain flammable dust,

gas, or liquid vapors (such as gasoline).

D 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, sparks, and fire

hazards.

D Do not use welder to thaw frozen pipes.

D Remove stick electrode from holder or cut off welding wire at

contact tip when not in use.

D Wear oil-free protective garments such as leather gloves, heavy

shirt, cuffless trousers, high shoes, and a cap.

D Remove any combustibles, such as a butane lighter or matches,

from your person before doing any welding.

D After completion of work, inspect area to ensure it is free of sparks,

glowing embers, and flames.

D Use only correct fuses or circuit breakers. Do not oversize or by-

pass them.

D Follow requirements in OSHA 1910.252 (a) (2) (iv) and NFPA 51B

for hot work and have a fire watcher and extinguisher nearby.

FLYING METAL or DIRT can injure eyes.

D Welding, chipping, wire brushing, and grinding

cause sparks and flying metal. As welds cool,

they can throw off slag.

D Wear approved safety glasses with side

shields even under your welding helmet.

BUILDUP OF GAS can injure or kill.

D Shut off shielding gas supply when not in use.

D Always ventilate confined spaces or use

approved air-supplied respirator.

ELECTRIC AND MAGNETIC FIELDS (EMF

)

can affect ImplantedMedical Devices.

D Wearers of Pacemakers and other Implanted

Medical Devices should keep away.

D Implanted Medical Device wearers should consult their doctor

and the device manufacturer before going near arc welding, spot

welding, gouging, plasma arc cutting, or induction heating

operations.

NOISE can damage hearing.

Noise from some processes or equipment can

damage hearing.

D Wear approved ear protection if noise level is

high.

Shielding gas cylinders contain gas under high

pressure. If damaged, a cylinder can explode. Since

gas cylinders are normally part of the welding

process, be sure to treat them carefully.

CYLINDERS can explode if damaged.

D Protect compressed gas cylinders from excessive heat, mechani-

cal shocks, physical damage, slag, open flames, sparks, and arcs.

D Install cylinders in an upright position by securing to a stationary

support or cylinder rack to prevent falling or tipping.

D Keep cylinders away from any welding or other electrical circuits.

D Never drape a welding torch over a gas cylinder.

D Never allow a welding electrode to touch any cylinder.

D Never weld on a pressurized cylinder − explosion will result.

D Use only correct shielding gas cylinders, regulators, hoses, and fit-

tings designed for the specific application; maintain them and

associated parts in good condition.

D Turn face away from valve outlet when opening cylinder valve.

D Keep protective cap in place over valve except when cylinder is in

use or connected for use.

D Use the right equipment, correct procedures, and sufficient num-

ber of persons to lift and move cylinders.

D Read and follow instructions on compressed gas cylinders,

associated equipment, and Compressed Gas Association (CGA)

publication P-1 listed in Safety Standards.

1-6. EMF Information

Electric current flowing through any conductor causes localized electric

and magnetic fields (EMF). Welding current creates an EMF field

around the welding circuit and welding equipment. EMF fields may inter-

fere with some medical implants, e.g. pacemakers. Protective

measures for persons wearing medical implants have to be taken. For

example, access restrictions for passers−by or individual risk assess-

ment for welders. All welders should use the following procedures in

order to minimize exposure to EMF fields from the welding circuit:

1. Keep cables close together by twisting or taping them, or using a

cable cover.

2. Do not place your body between welding cables. Arrange cables

to one side and away from the operator.

3. Do not coil or drape cables around your body.

4. Keep head and trunk as far away from the equipment in the

welding circuit as possible.

5. Connect work clamp to workpiece as close to the weld as

possible.

6. Do not work next to, sit or lean on the welding power source.

7. Do not weld whilst carrying the welding power source or wire

feeder.

About Implanted Medical Devices:

Implanted Medical Device wearers should consult their doctor and the

device manufacturer before performing or going near arc welding, spot

welding, gouging, plasma arc cutting, or induction heating operations.

If cleared by your doctor, then following the above procedures is recom-

mended.
