kneeling or lying, if there is a high risk of unavoidable or accidental contact with the work
piece or ground) use the following equipment:
Semiautomatic DC Constant Voltage (Wire) Welder
DC Manual (Stick) Welder
AC Welder with Reduced voltage control
3.c. In semiautomatic or automatic wire welding, the electrode, electrode reel, welding head,
nozzle or semiautomatic welding gun are also electrically “hot”.
3.d. 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.
3.e. Ground the work or metal to be welded to a good electrical (earth) ground.
3.f. Maintain the electrode holder, work clamp, welding cable and welding machine in good,
safe operating condition. Replace damaged insulation.
3.g. Never dip the electrode in water for cooling.
3.h. Never simultaneously touch electrically “hot” parts of electrode holders connected to two
welders because voltage between the two can be the total of the open circuit voltage of
both welders.
3.i. When working above floor level, use a safety belt to protect yourself from a fall
ARC RAYS can burn.
4.a. 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 observing open arc welding. Head shield and filter lens
should conform to standard.
4.b. Use suitable clothing made from durable flame-resistant material to protect your skin and
that of your helpers from the arc rays.
4.c. protect other nearby personnel with suitable, non-flammable screening and/or warn them
not to watch the arc nor expose themselves to the arc rays or to hot spatter or material.
