1-2. Arc Welding Hazards

WARNING

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 1-4. 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.

1. Do not touch live electrical parts.

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

3. Insulate yourself from work and ground using dry insulating mats

or covers big enough to prevent any physical contact with the

work or ground.

4. 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).

5. Properly install and ground this equipment according to its

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

6. 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.

7. When making input connections, attach proper grounding

conductor first − double-check connections.

8. Frequently inspect input power cord for damage or bare wiring −

replace cord immediately if damaged − bare wiring can kill.

9. Turn off all equipment when not in use.

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

11. Do not drape cables over your body.

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

with a separate cable − do not use work clamp or work cable.

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

or another electrode from a different machine.

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

parts at once. Maintain unit according to manual.

15. Wear a safety harness if working above floor level.

16. Keep all panels and covers securely in place.

17. Clamp work cable with good metal-to-metal contact to workpiece

or worktable as near the weld as practical.

ARC RAYS can burn eyes and skin;

NOISE can damage hearing; FLYING

SLAG OR SPARKS can injure eyes.

Arc rays from the welding process produce intense

visible and invisible (ultraviolet and infrared) rays

that can burn eyes and skin. Noise from some

processes can damage hearing. Chipping, grinding,

and welds cooling throw off pieces of metal or slag.

NOISE

1. Use approved ear plugs or ear muffs if noise level is high.

ARC RAYS

2. 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).

3. Wear approved safety glasses with side shields.

4. Use protective screens or barriers to protect others from flash

and glare; warn others not to watch the arc.

5. Wear protective clothing made from durable, flame-resistant

material (wool and leather) and foot protection.

FUMES AND GASES can be

hazardous to your health.

Welding produces fumes and gases. Breathing

these fumes and gases can be hazardous to your

health.

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

2. If inside, ventilate the area and/or use exhaust at the arc to

remove welding fumes and gases.

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

4. Read the Material Safety Data Sheets (MSDSs) and the

manufacturer’s instruction for metals, consumables, coatings,

cleaners, and degreasers.

5. 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.

6. 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.

7. 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-180 058 Page 2

CYLINDERS can explode if damaged.

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.

1. Protect compressed gas cylinders from excessive heat,

mechanical shocks, slag, open flames, sparks, and arcs.

2. Install cylinders in an upright position by securing to a stationary

support or cylinder rack to prevent falling or tipping.

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

4. Never drape a welding torch over a gas cylinder.

5. Never allow a welding electrode to touch any cylinder.

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

7. Use only correct shielding gas cylinders, regulators, hoses, and

fittings designed for the specific application; maintain them and

associated parts in good condition.

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

9. Keep protective cap in place over valve except when cylinder is in

use or connected for use.

10. Read and follow instructions on compressed gas cylinders,

associated equipment, and CGA publication P-1 listed in Safety

Standards.

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 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.

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

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

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

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

4. Be alert that welding sparks and hot materials from welding can

easily go through small cracks and openings to adjacent areas.

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

6. Be aware that welding on a ceiling, floor, bulkhead, or partition

can cause fire on the hidden side.

7. 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).

8. 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.

9. Do not use welder to thaw frozen pipes.

10. Remove stick electrode from holder or cut off welding wire at

contact tip when not in use.

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

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

12. Remove any combustibles, such as a butane lighter or matches,

from your person before doing any welding.

1-3. Additional Installation, Operation, And Maintenance Hazards

FIRE OR EXPLOSION can result from

placing unit on, over, or near

combustible surfaces.

1. Do not locate unit on, over, or near combustible

surfaces.

2. Do not install unit near flammables.

FALLING EQUIPMENT can cause

serious personal injury and equipment

damage.

1. Use lifting eye to lift unit only, NOT running gear,

gas cylinders, or any other accessories.

2. Use equipment of adequate capacity to lift unit.

3. If using lift forks to move unit, be sure forks are long

enough to extend beyond opposite side of unit.

HOT PARTS can cause severe burns.

1. Do not touch hot parts bare handed.

2. Allow cooling period before working on gun or

torch.

MOVING PARTS can cause injury.

1. Keep away from moving parts such as fans.

2. Keep all doors, panels, covers, and guards closed

and securely in place.

MAGNETIC FIELDS FROM HIGH

operations.

MOVING PARTS can cause injury.

1. Keep away from moving parts.

2. Keep away from pinch points such as drive rolls.

FLYING PIECES OF METAL or DIRT can

injure eyes.

1. Wear safety glasses with side shields or face

shield.

WELDING WIRE can cause puncture

wounds.

1. Do not press gun trigger until instructed to do so.

2. Do not point gun toward any part of the body, other

people, or any metal when threading welding wire.

HIGH-FREQUENCY RADIATION can

interfere with radio navigation, safety

services, computers, and

communications equipment.

1. Have only qualified persons familiar with electronic

equipment perform this installation.

2. The user is responsible for having a qualified

electrician promptly correct any interference

problem resulting from the installation.

3. If notified by the FCC about interference, stop using

the equipment at once.

4. Have the installation regularly checked and

maintained.

5. Keep high-frequency source doors and panels

tightly shut, keep spark gaps at correct setting, and

use grounding and shielding to minimize the

possibility of interference.

OM-180 058 Page 3

OVERUSE can cause OVERHEATED

EQUIPMENT.

1. Allow cooling period.

2. Reduce current or reduce duty cycle before

starting to weld again.

3. Follow rated duty cycle.

STATIC ELECTRICITY can damage

parts on circuit boards.

1. Put on grounded wrist strap BEFORE handling

boards or parts.

2. Use proper static-proof bags and boxes to store,

move, or ship PC boards.

SIGNIFICANT DC VOLTAGE exists after

removal of input power on inverters.

1. Turn Off inverter, disconnect input power, and

discharge input capacitors according to

instructions in Maintenance Section before

1-5. EMF Information

Considerations About Welding And The Effects Of Low Frequency

Electric And Magnetic Fields

The following is a quotation from the General Conclusions Section of

the U.S. Congress, Office of Technology Assessment, Biological

Effects of Power Frequency Electric & Magnetic Fields − Background

Paper, OTA-BP-E-53 (Washington, DC: U.S. Government Printing

Office, May 1989): “. . . there is now a very large volume of scientific

findings based on experiments at the cellular level and from studies

with animals and people which clearly establish that low frequency

magnetic fields can interact with, and produce changes in, biological

systems. While most of this work is of very high quality, the results are

complex. Current scientific understanding does not yet allow us to

interpret the evidence in a single coherent framework. Even more

frustrating, it does not yet allow us to draw definite conclusions about

questions of possible risk or to offer clear science-based advice on

strategies to minimize or avoid potential risks.”

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 the body.

4. Keep welding power source and cables as far away as

practical.

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

possible.

About Pacemakers:

The above procedures are also recommended for pacemaker

wearers. Consult your doctor for complete information.
