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 the

exact part you may need to fix the problem.

Warranty and service information for your

particular model are also provided.

Miller is the first welding

equipment manufacturer in

the U.S.A. to be registered to

the ISO 9001:2000 Quality

System Standard.

Working as hard as you do

− every power source from

Miller is backed by the most

hassle-free warranty in the

business.

to avoid the hazards.

1-2. Arc Welding Hazards

Y 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.

Y Only qualified persons should install, operate, maintain, and

repair this unit.

Y 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 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 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 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 after removal of

input power on inverters.

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

capacitors according to instructions in Maintenance Section

before touching any parts.

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 exhaust at the arc to remove

welding fumes and gases.

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

D Read 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 if necessary, while wearing an

air-supplied respirator. The coatings and any metals containing

these elements can give off toxic fumes if welded.

OM-220 979 Page 2

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.

ARC RAYS can burn eyes and skin.

D Wear a welding helmet fitted with a proper shade of filter to protect

your face and eyes 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 and

glare; warn others not to watch the arc.

D Wear protective clothing made from durable, flame-resistant mate-

rial (leather and wool) and foot protection.

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 Protect yourself and others from flying sparks and hot metal.

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

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 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 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.

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.

FLYING METAL 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.

HOT PARTS can cause severe burns.

D Do not touch hot parts bare handed.

D Allow cooling period before working on gun or

torch.

MAGNETIC FIELDS can affect pacemakers.

D Pacemaker wearers keep away.

D Wearers should consult their doctor before

going near arc welding, gouging, or spot

welding 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, 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.

1-6. EMF Information

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-health hazard.”

However, studies are still going forth and evidence 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:

1. Keep cables 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 opera-

tor as practical.

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

ble.

About Pacemakers:

Pacemaker wearers consult your doctor first. If cleared by your doctor,

then following the above procedures is recommended.

2-5. Information sur les champs électromagnétiques

Données sur le soudage électrique et les effets des champs magnéti-

ques basse fréquence sur l’organisme

En parcourant les câbles de soudage, le courant crée des champs élec-

tromagnétiques. Les effets potentiels de tels champs restent

préoccupants. Cependant, après avoir examiné plus de 500 études qui

ont été faites pendant une période de recherche de 17 ans, un comité

de spécialistes du National Research Council a conclu : « L’accumula-

tion de preuves n’a pas démontré que l’exposition aux champs

magnétiques et aux champs électriques à haute fréquence constitue un

risque pour la santé humaine ». Toutefois, les études et l’examen des

preuves se poursuivent. En attendant les conclusions finales de la re-

cherche, il serait souhaitable de réduire l’exposition aux champs

électromagnétiques pendant le soudage ou le coupage.

Afin de réduire les champs électromagnétiques en milieu de travail, res-

pecter les consignes suivantes :

1. Garder les câbles ensemble en les torsadant ou en les fixant avec du

ruban adhésif.

2. Mettre tous les câbles du côté opposé à l’opérateur.

3. Ne pas s’enrouler les câbles autour du corps.

4. Garder le poste de soudage et les câbles le plus loin possible de soi.

5. Placer la pince de masse le plus près possible de la zone de soudage.

Consignes relatives aux stimulateurs cardiaques :

Les personnes qui portent un stimulateur cardiaque doivent avant tout

consulter leur médecin. Si ce dernier les déclare aptes, il leur est recom-

mandé de respecter les consignes ci-dessus.

SECTION 6 − OPERATION

6-1. Operational Terms

The following is a list of terms and their definitions as they apply to the interface unit in the wire feeder:

General Terms:

Arc Adjust Term used to represent arc length adjustments in pulse programs. Increasing Arc Adjust increases

the actual arc length. Likewise, decreasing arc adjust shortens arc length. Arc Adjust is replaced by

volts in MIG programs.

Trigger Control Selecting Trigger Control allows activating trigger functions such as DS, TH, 4T, TDS, and TPS.

DS (Dual Schedule) Dual Schedule allows selecting a pair of programs that can be used together.

TH (Trigger Hold) Trigger Hold allows the operator to feed wire without continuously pressing the gun trigger. In trigger

hold mode, momentarily press gun trigger, and wire will feed until gun trigger is momentarily pressed

again.

4T 4T allows the operator to select between weld parameters and crater parameters using the gun

trigger. Crater time must be set for at least 0.2 seconds to make this function operational. If gun

trigger is released during welding, unit goes into trigger hold, then pressing and holding trigger again

causes unit to stay in crater until trigger is released and crater parameter times out.

TDS (Trigger Dual Schedule) TDS allows the operator to select between a pair of weld programs by using the gun trigger. In TDS

mode, momentarily pressing the gun trigger allows the operator to cycle between a pair of preselected

weld programs.

TPS (Trigger Program Schedule) TPS allows the operator to select weld programs by using the gun trigger. In TPS mode, momentarily

pressing the gun trigger allows the operator to cycle through preselected weld programs up to a total

of 8 programs.

Program Eight active slots for selection of various processes, wire type, and parameters.

Process A selection made for MIG, Pulse, Accu-pulse, and RMD (optional).

MIG CV weld process with individual settings of voltage and wire speed.

Pulse Conventional pulse program using peak, background, pulse width, frequency, and peak voltage as

factory taught data. Adaptive method is controlled by frequency adjustment.

Accu-pulse Pulse process utilizing constant current ramps with constant voltage control of peaks and

backgrounds. Adaptive response is controlled by peak and minimum current levels. Benefits are

shorter arc lengths, better puddle control, more tolerant of tip-to-work variation, less audible noise, no

arc wandering, allows weld to fill in at toes increasing travel speed and deposition, and more tolerant

to poor fit up and gaps.

RMD (optional) RMD refers to Regulated Metal Deposition. A precisely controlled short-circuit transfer. Benefits of

RMD are well suited to thin materials, improves gap filling and spatter reduction. Provides less heat

input into workpiece, minimizes distortion and allows use of larger diameter wire on thin gauge

materials.

Wire Type Selection of wire type by alloys and classification.

Gas Type Selection of shielding gas being used in application.

Process Set Up Selection procedure for entering program.

Program Load Enters selected program information into program slot.

Volts Preset voltage in MIG mode at idle, actual voltage while welding, and 3 seconds hold value at end of

weld.

Time Indicates time values being set for timed functions (e.g. Preflow, Postflow which are only available in

the Arc On and Analog input or the Arc On and No Analog input modes).

Arc Length Distance from end of wire electrode to workpiece.

WFS Term used to represent wire feed speed. In MIG mode, wire feed setting is independent of voltage

setting. In pulse, Accu-pulse, and RMD (optional) adjusting wire feed speed also increases power

level on wire electrode (one knob control).

Amps Indicates average amperage while welding and 3 seconds hold value at end of weld.

Arc Control Allows setting of inductance in MIG mode. In pulse and Accu-pulse mode, this adjustment changes

the arc cone by adjusting the preprogrammed factory pulse data. In RMD (optional), this control will

affect the in much the same way as inductance.

Inductance In short circuit GMAW welding, an increase in inductance will decrease the number of short circuit

transfers per second (provided no other changes are made) and increase the arc-on time. The

increased arc-on time makes the welding puddle more fluid.

Adjust Control knob used to change or set parameters and functions.

Sequence Selecting Sequence will allow setting of preflow, start, crater, and postflow times and parameters.

Preflow Setting a time value for gas flow prior to arc start.

Start Provides voltage/arc adjust, wire feed rate, and time value for modified arc starts (which is only

adjustable with the optional PDA with File Management/WaveWriter software).

OM-220 979 Page 16

General Terms:

Crater Allows setting of voltage/arc adjust, wire feed rate, and time value for arc ends.

Postflow Setting a time value for gas flow after arc end.

Feeder Set Up Allow selection of Sequence and trigger functions.

Auto Thread Method of jogging wire without holding jog or trigger switch. Pressing Jog and Retract simultaneously

will automatically feed wire. Default setting is 192 at a feed rate of 700 ipm (these values can be

changed using a PDA with File Management/WaveWriter software). Pressing jog, purge, or trigger

switch will terminate the auto-threading feature.
