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 weld output in damp, wet, or confined spaces, 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 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 unavoid­able or accidental contact with the workpiece or ground. For these conditions, use the following equipment in order presented: 1) a semiautomatic (stick) welder, or 3) an AC welder with reduced open-circuit volt­age. 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).

FUMES AND GASES can be hazardous.
Welding produces fumes and gases. Breathing these fumes and gases can be hazardous to your health.
D Keep your head out of the fumes. Do not breathe the fumes. D Ventilate the work area and/or use local forced ventilation at the arc
to remove welding fumes and gases. The recommended way to determine adequate ventilation is to sample for the composition and quantity of fumes and gases to which personnel are exposed.
D If ventilation is poor, wear an approved air-supplied respirator. D Read and understand the Safety Data Sheets (SDSs) and the
manufacturer’s instructions for adhesives, coatings, cleaners, consumables, coolants, degreasers, fluxes, and metals.
D Work in a confined space only if it is well ventilated, or while
wearing an air-supplied respirator. Always have a trained watch­person nearby. Welding fumes and gases can displace air and lower the oxygen level causing injury or death. Be sure the breath­ing 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 can burn eyes and skin.
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 body protection made from durable, flame−resistant mate-
rial (leather, heavy cotton, wool). Body protection includes oil-free clothing such as leather gloves, heavy shirt, cuffless trousers, high shoes, and a cap.
D Do not cut or weld on tire rims or wheels. Tires can explode if heat-
ed. Repaired rims and wheels can fail. See OSHA 29 CFR
1910.177 listed in Safety Standards.
D Do not weld on containers that have held combustibles, or on
closed containers such as tanks, drums, or pipes unless they are properly prepared according to AWS F4.1 and AWS A6.0 (see Safety Standards).
D Do not weld where the atmosphere can 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 body protection made from durable, flame−resistant material
(leather, heavy cotton, wool). Body protection includes oil-free clothing 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.
D Read and understand the Safety Data Sheets (SDSs) and the
manufacturer’s instructions for adhesives, coatings, cleaners, consumables, coolants, degreasers, fluxes, and metals.
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 compressed gas supply when not in use. D Always ventilate confined spaces or use
approved air-supplied respirator.
WELDING can cause fire or explosion.
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
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.
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.

CYLINDERS can explode if damaged.
Compressed 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.
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 compressed gas cylinders, regulators, hoses,
and fittings designed for the specific application; maintain them and associated parts in good condition.

1-6. EMF Information
Electric current flowing through any conductor causes localized electric and magnetic fields (EMF). The current from arc welding (and allied pro­cesses including spot welding, gouging, plasma arc cutting, and induction heating operations) creates an EMF field around the welding circuit. EMF fields can interfere with some medical implants, e.g. pace­makers. Protective measures for persons wearing medical implants have to be taken. For example, restrict access for passers−by or con- duct individual risk assessment 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.
OM-252717 Page 4
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 recom­mended.

Pressing the Jog/Purge switch allows the op­erator to jog wire without energizing the weld power or gas valve circuit.
The unit provides the ability to jog the wire feeder by means of the gun trigger or the Jog/Purge switch. If the welding arc does not initiate in 3 seconds after the gun trigger is activated, the unit will perform a jog opera­tion for a maximum of two minutes. If the gun
trigger is still activated after two minutes, the jog operation is terminated to prevent com­plete despooling of the wire, in the case of a damaged gun.
The unit displays the “ERR TRIG“ message to inform the operator that the trigger is acti­vated.
Jog speed can be adjusted by the Adjust control when the unit is jogging wire. The
Ref. 803184-B
unit displays jog speed when the unit is be­ing jogged.
Jogging can also be accomplished by pressing the Jog/Purge button.
Pressing the Jog/Purge button also allows the operator to purge gas lines before weld­ing and to preset gas pressure at the regulator.

weld without holding the gun trigger.
To use the trigger hold function, place the trigger hold switch in the On position.
The operator must hold the trig­ger for a minimum of 2 seconds, but not longer than 6 seconds be­fore releasing it. Welding will con­tinue when the trigger is re­leased.
To stop welding, press the trigger again.

Error Indications
Error conditions are indicated by LED3 on PC1, PC101, PC70 or on display if meter op­tion is present. To view LED3, turn Off unit, re­move wrapper, and turn unit On. LED3 is most easily observed from the left side of the unit.
The LED blinks in a 2.5 second cycle. The number of blinks in this period indicates the type of error.
The priority of the errors is related to the num­ber of blinks indicating the error. The more blinks, the more severe the error (motor error is top priority). A higher priority error overrides

a lower one (if a motor error and a communica­tion error existed, the light would blink four times for the motor error).
The communication error occurs 2.5 sec- onds after a loss of communication between the motor and the optional meter board or Dual board. The user may continue to weld with this error. The error may be cleared by turning power Off, waiting a minimum of two seconds, and turning power On.
The trigger error occurs if the user has the trigger held for more than two minutes with­out striking an arc (providing current over-

ride is not enabled), or if the user holds the trigger past the postflow phase in a timed weld. This error also occurs if the trigger is held when the feeder is powered up. The er­ror may be cleared by releasing the trigger.
The tach error occurs 2 seconds after the loss of tachometer feedback. The user may continue to weld with this error. The motor speed is regulated through the monitoring of voltage and current.
The motor error indicates that the motor has been drawing too much current for too long.

Miller’s True Blue® Limited Warranty shall not apply to:

cutting nozzles, contactors, brushes, relays, work station table tops and welding curtains, or parts that fail due to normal wear. (Exception: brushes and relays are covered on all engine-driven products.)
2. Items furnished by Miller, but manufactured by others, such as engines or trade accessories. These items are covered by the manufacturer’s warranty, if any.
3. Equipment that has been modified by any party other than Miller, or equipment that has been improperly installed, improperly operated or misused based upon industry standards, or equipment which has not had reasonable and necessary maintenance, or equipment which has been used for operation outside of the specifications for the equipment.
4. Defects caused by accident, unauthorized repair, or improper testing.
MILLER PRODUCTS ARE INTENDED FOR COMMERCIAL AND INDUSTRIAL USERS TRAINED AND EXPERIENCED IN THE USE AND MAINTENANCE OF WELDING EQUIPMENT.
The exclusive remedies for warranty claims are, at Miller’s option, either: (1) repair; or (2) replacement; or, if approved in writing by Miller, (3) the pre-approved cost of repair or replacement at an authorized Miller service station; or (4) payment of or credit for the purchase price (less reasonable depreciation based upon use). Products may not be returned without Miller’s written approval. Return shipment shall be at customer’s risk and expense.
The above remedies are F.O.B. Appleton, WI, or Miller’s authorized service facility. Transportation and freight are the customer’s responsibility. TO THE EXTENT PERMITTED BY LAW, THE REMEDIES HEREIN ARE THE SOLE AND EXCLUSIVE REMEDIES REGARDLESS OF THE LEGAL THEORY. IN NO EVENT SHALL MILLER BE LIABLE FOR DIRECT, INDIRECT, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES (INCLUDING LOSS OF PROFIT) REGARDLESS OF THE LEGAL THEORY. ANY WARRANTY NOT PROVIDED HEREIN AND ANY IMPLIED WARRANTY, GUARANTY, OR REPRESENTATION, INCLUDING ANY IMPLIED WARRANTY OF MERCHANTABILITY OR FITNESS FOR PARTICULAR PURPOSE, ARE EXCLUDED AND DISCLAIMED BY MILLER.
Some US states do not allow limiting the duration of an implied warranty or the exclusion of certain damages, so the above limitations may not apply to you. This warranty provides specific legal rights, and other rights may be available depending on your state. In Canada, some provinces provide additional warranties or remedies, and to the extent the law prohibits their waiver, the limitations set out above may not apply. This Limited Warranty provides specific legal rights, and other rights may be available, but may vary by province.
