ELECTRIC SHOCK
Electric shock can injure or kill!
Precautionary measures must be taken to provide maximum protection against
electrical 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 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
