1-2. GMAW Gun Hazards

WARNING

GMAW WELDING can be hazardous.

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 found in the wire feeder and welding power source Owner’s Manuals. Read and follow all safety precautions.

HAVE ALL INSTALLATION, OPERATION, MAINTENANCE, AND REPAIR WORK PERFORMED ONLY BY QUALIFIED PEOPLE.

ELECTRIC SHOCK can kill.

1.Always wear dry insulating gloves.

2.Insulate yourself from work and ground.

3.Do not touch live electrode or electrical parts.

4.Repair or replace worn, damaged, or cracked gun or cable insulation.

5.Turn off welding power source before changing contact tip or gun parts.

6.Keep all covers and handle securely in place.

FUMES AND GASES can be hazardous to your health.

1.Keep your head out of the fumes.

2.Ventilate area, or use breathing device.

3.Read Material Safety Data Sheets (MSDSs) and manufacturer’s instructions for material used.

WELDING can cause fire or explosion.

1.Do not weld near flammable material.

2.Do not weld on closed containers.

3.Watch for fire; keep extinguisher nearby.

ARC RAYS can burn eyes and skin.

1.Wear welding helmet with correct shade of filter.

2.Wear correct eye and body protection.

3.Cover exposed skin with spatter-resistant clothing.

HOT SURFACES can burn skin.

1.Allow gun to cool before touching.

2.Do not touch hot metal.

3.Protect hot metal from contact by others.

NOISE can damage hearing; SOME APPLICATIONS, SUCH AS PULSING, are noisy.

1.Check for noise level limits exceeding those specified by OSHA.

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

3.Warn others nearby about noise hazard.

WELDING WIRE can cause puncture wounds.

1.Keep hands and body away from gun tip when trigger is pressed.

BUILD UP OF GAS can injure or kill

1.Shut off shielding gas supply when not in use.

2.Always ventilate confined spaces or use approved air-supplied respirator.
