This group of symbols means Warning! Watch Out! possible ELECTRIC SHOCK, MOVING PARTS, and HOT PARTS hazards. Consult symbols and related instructions below for necessary actions to avoid the hazards.
D If earth grounding of the workpiece is required, ground it directly
with a separate cable – do not use work clamp or work 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.
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 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 watch­person nearby. Welding fumes and gases can displace air and lower th e 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 if necessary, 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.
BUILDUP OF GAS can injure or kill.
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 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 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 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.
workpiece, and hot equipment can cause fires and
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.
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.

1-5. EMF Information
Considerations About Welding And The Effects Of Low Frequency Electric And Ma g netic Fields
Welding current, as it flows through welding cables, will cause electro­magnetic 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 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.

WARNING
ELECTRIC SHOCK can kill.
Do not touch live electrical parts.
Turn Off welding power sources by placing Power
circuit breakers in the Of f position before making any weld output connections.
Do not connect welding output of different polarities
to the same structure.
See ANSI Z49.1 and OSHA Title 29, Chapter XVII,
Part 1910, Subpart Q (addresses at beginning of manual).
Do not handle or come in contact with two live
electrodes a t the same time.
UNDERSIZED WELDING CABLES can cause fire.
Use single cables of adequate capacity to carry the
total combined amperage of the paralleled welding power sources.

ARCING can burn skin or damage electrical equipment.
Do not change position of the welding cable
connectors while welding.
Be sure the connectors are secure in receptacles
before welding.
INADEQUATE WORK CABLE CONNECTIONS can cause serious damage to input power service and create a hazardous condition.
Connect an electrical cable of adequate size
between the isolated terminal and the workpiece whenever any welding power sources are connected t o the isolated terminal.
Set the Amperage/Voltage control on all paralleled welding power sources to the same value. The iso­lated terminal may be used as a common connection point if no other connections are made to it.
The procedure shown is for Electrode Positive welding connections.
1 Weld Output Cables Determine cable sizes according to
welding power source Owner’s Manual. Cables must reach cable connection point. Cables con­nected together must be the same polarity.
2 Connection Point Cover with proper insulating
material after making connections. 3 Terminal Lugs Use lugs of proper amperage

*
These values are calculated from the 1993 edition of the National Electrical Code (NEC).
1 Recommended fuse or circuit breaker size is that closest to 150% of rated input amperage of the welding power source. Article 630-12(a) of NEC
allows fuse or circuit breaker sizing up to 200% of rated input amperage.
2 Input conductor size is for insulated copper wire with 75°C rating with not more than three single current-carrying conductors in a cable or raceway
(Table 310-16 of NEC).
3 Maximum length is to prevent more than a 3% voltage drop between service entrance and input terminals of the welding power source (Articles
210-19(a) and 215-2(b) of NEC).
4 The grounding conductor shall be colored or identified as specified in the NEC. Grounding conductor size for copper wire is not required to be larger
than input conductor (Article 250-95 of NEC).
