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
welded. 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.
