Electrical Safety

ELECTRIC SHOCK can KILL.

SAFETY

SETUP

1.Turn off, disconnect power, and

discharge electrode to ground before setting down torch/electrode holder and before service.

2.Do not touch energized electrical parts.

Wear dry, insulating gloves. Do not touch electrode holder, electrode, welding torch, or welding wire with bare hand. Do not wear wet or damaged gloves.

3.Connect to grounded, GFCI‑protected power supply only.

4.Do not use near water or damp objects.

5.People with pacemakers should consult their physician(s) before use. Electromagnetic fields in close proximity to heart pacemaker could cause pacemaker interference or pacemaker failure.

6.Do not expose welders to rain or wet conditions.

Water entering a welder will increase the risk of electric shock.

7.Do not abuse the cord. Never use the cord for carrying, pulling or unplugging the welder. Keep cord away from heat, oil, sharp edges or moving parts. Damaged or entangled cords increase the risk of electric shock.

8.Do not use outdoors.

9.Insulate yourself from the workpiece and ground.

Use nonflammable, dry insulating material if possible, or use dry rubber mats, dry wood or plywood, or other dry insulating material large enough to cover your full area of contact with the work or ground.

BASIC

Fire Safety

ARC AND HOT SLAG can cause fire.

WELDING

WELDING TIPS

MAINTENANCE

1.Clear away or protect flammable objects.

Remove or make safe all combustible materials for a radius of 35 feet (10 meters) around the work area. Use a fire resistant material to cover or block all open doorways, windows, cracks, and other openings.

2.Keep ABC-type fire extinguisher near work area and know how to use it.

3.Maintain a safe working environment.

Keep the work area well lit.

Make sure there is adequate surrounding workspace. Keep the work area free of obstructions,

grease, oil, trash, and other debris.

4.Do not operate welders in atmospheres containing dangerously reactive or flammable liquids, gases, vapors, or dust.

Provide adequate ventilation in work areas to prevent accumulation of such substances. Welders create sparks which may ignite flammable substances or make reactive fumes toxic.

5.If working on a metal wall, ceiling, etc., prevent ignition of combustibles on the other side by moving the combustibles to a safe location. If relocation of combustibles is not possible, designate someone to serve as a fire watch, equipped with a fire extinguisher, during the cutting process and for at least one half hour after the cutting is completed.

6.Do not weld or cut on materials having a combustible coating or combustible

internal structure, as in walls or ceilings, without an approved method for eliminating the hazard.

7.Do not dispose of hot slag in containers holding combustible materials.

8.After welding, make a thorough examination for evidence of fire. Be aware that easily visible smoke or flame may not be present

for some time after the fire has started.

9.Do not apply heat to a container that has held an unknown substance or a combustible material whose contents, when heated,

can produce flammable or explosive vapors.

Clean and purge containers before applying heat. Vent closed containers, including castings, before preheating, welding, or cutting.
