ARC WELDING SAFETY PRECAUTIONS  
ARC WELDING can be hazardous.  
WARNING  
PROTECT YOURSELF AND OTHERS FROM POSSIBLE SERIOUS INJURY OR DEATH. KEEP CHILDREN  
AWAY. PACEMAKER WEARERS KEEP AWAY UNTIL CONSULTING YOUR DOCTOR.  
In welding, as in most jobs, exposure to certain hazards occurs. Welding is safe when precautions are taken. The  
safety information given below is only a summary of the more complete safety information that will be found in the  
Safety Standards listed on the next page. Read and follow all Safety Standards.  
HAVE ALL INSTALLATION, OPERATION, MAINTENANCE, AND REPAIR WORK PERFORMED ONLY BY  
QUALIFIED PEOPLE.  
in disconnect box or that cord plug is connected to a properly  
groundedreceptacle outlet.  
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  
groundedequipment is a hazard.  
7. When making input connections, attach proper grounding  
conductor first double-check connections.  
8. Frequentlyinspect 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.  
1. Do not touch live electrical parts.  
12. If earth grounding of the workpiece is required, ground it directly  
2. Wear dry, hole-free insulating gloves and body protection.  
with a separate cable do not use work clamp or work cable.  
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.  
13. Do not touch electrode if you are in contact with the work, ground,  
or another electrode from a different machine.  
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).  
14. Use only well-maintained equipment. Repair or replace  
damagedparts 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.  
5. Properly install and ground this equipment according to its  
Owners Manual and national, state, and local codes.  
6. Always verify the supply ground check and be sure that input  
17. Clamp work cable with good metal-to-metal contact to workpiece  
or worktable as near the weld as practical.  
power cord ground wire is properly connected to ground terminal  
ARC RAYS  
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.  
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.  
NOISE  
5. Wear protective clothing made from durable, flame-resistant  
material(wool and leather) and foot protection.  
1. Use approved ear plugs or ear muffs if noise level is high.  
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.  
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.  
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.  
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  
manufacturers instruction for metals, consumables, coatings,  
cleaners, and degreasers.  
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  
containingthese elements can give off toxic fumes if welded.  
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.  
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.  
8. Turn face away from valve outlet when opening cylinder valve.  
1. Protect compressed gas cylinders from excessive heat,  
mechanical shocks, slag, open flames, sparks, and arcs.  
9. Keep protective cap in place over valve except when cylinder is  
in use or connected for use.  
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.  
10. Read and follow instructions on compressed gas cylinders,  
associated equipment, and CGA publication P-1 listed in Safety  
Standards.

6. Be aware that welding on a ceiling, floor, bulkhead, or partition  
can cause fire on the hidden side.  
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.  
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.  
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.  
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.  
ENGINES can be hazardous.  
WARNING  
ENGINE EXHAUST GASES can kill.  
1. Use equipment outside in open, well-ventilated areas.  
Engines produce harmful exhaust gases.  
2. If used in a closed area, vent engine exhaust outside and away  
from any building air intakes.  
3. Do not overfill tank allow room for fuel to expand.  
4. Do not spill fuel. If fuel is spilled, clean up before starting  
engine.  
ENGINE FUEL can cause fire or  
explosion.  
Engine fuel is highly flammable.  
1. Stop engine and let it cool off before checking or adding fuel.  
2. Do not add fuel while smoking or if unit is near any sparks or  
open flames.  
3. Have only qualified people remove guards or covers for  
maintenanceand troubleshooting as necessary.  
MOVING PARTS can cause injury.  
Moving parts, such as fans, rotors, and belts can cut  
fingers and hands and catch loose clothing.  
4. To prevent accidental starting during servicing, disconnect  
negative () battery cable from battery.  
5. Keep hands, hair, loose clothing, and tools away from moving  
parts.  
1. Keep all doors, panels, covers, and guards closed and  
securely in place.  
6. Reinstall panels or guards and close doors when servicing is  
finished and before starting engine.  
2. Stop engine before installing or connecting unit.  
1. Always wear a face shield when working on a battery.  
SPARKS can cause BATTERY  
GASES TO EXPLODE; BATTERY  
ACID can burn eyes and skin.  
2. Stop engine before disconnecting or connecting battery  
cables.  
3. Do not allow tools to cause sparks when working on a battery.  
4. Do not use welder to charge batteries or jump start vehicles.  
5. Observe correct polarity (+ and ) on batteries.  
Batteries contain acid and generate explosive  
gases.  
1. If the engine is warm and checking is needed, follow steps 2  
and 3.  
2. Wear safety glasses and gloves and put a rag over cap.  
3. Turn cap slightly and let pressure escape slowly before  
completely removing cap.  
STEAM AND PRESSURIZED HOT  
COOLANT can burn face, eyes, and  
skin.  
It is best to check coolant level when engine is cold  
to avoid scalding.

Considerations About Welding And The Effects Of Low Frequency Electric And  
Magnetic Fields  
NOTE  
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.  
GovernmentPrinting 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  
understandingdoes 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 among those also normally  
recommended for pacemaker wearers. Consult your doctor for  
complete information.
