ELECTRIC SHOCK
Electric shock can injure or kill!
Precautionary measures must be taken to provide maximum protection against electri-
cal shock.
Do not touch live or energized electrical parts or store metallic objects near power.
Ground the work or metal to be welded to a good electrical (earth) ground.
Do not leave an energized machine unattended.
Never work in wet clothing, gloves or footwear.
Insulate yourself from work and ground using dry insulation. Make certain the insulation is
large enough to cover your full area of physical contact with work and ground.
Inspect all system components, protective equipment, cables, connectors and gas lines prior
to operating equipment. Never use cables that are longer than necessary.
When testing a live unit, use the one
-
hand method. Do not put both hands inside of the unit.
Keep one hand free.
Disconnect input power conductors from de
-
energized supply line before moving a welding
power source.
Always be sure the work cable makes a good electrical connection with the metal being weld-
ed. The connection should be as close as possible to the area being welded.
Turn OFF welding power source before servicing unless the procedure specifically requires an
energized unit.
Never touch the energized stud or gun before discharging the stud to ground.
Never use the power source to provide heat for thawing frozen pipes.
ARC RAYS and EYE PROTECTION
Arc rays can injure eyes and burn skin.
Arc flashes are painful.
Use a shield with the proper filter and cover plates to protect your eyes from sparks and the
rays of the arc when welding or while observing open arc welding.
Use protective clothing specifically intended for work with welding equipment. It should be
made of durable flame
-
resistant material to provide ample protection from the arc rays.
Protect other nearby workers with suitable, non
-
flammable screening. Caution other workers
not to watch the arc nor expose themselves to the arc rays or to hot spatter or metal.
