Electric Shock Can Kill - Lincoln Electric Stick Electrode Welding C2.410 Manual

full area of physical contact with work and ground.
In addition to the normal safety precautions, if welding must be per-
formed under electrically hazardous conditions (in damp locations or
while wearing wet clothing; on metal structures such as floors, gratings
or scaffolds; when in cramped positions such as sitting, kneeling or
lying, if there is a high risk of unavoidable or accidental contact with
the workpiece or ground) use the following equipment:
• Semiautomatic DC Constant Voltage (Wire) Welder.
• DC Manual (Stick) Welder.
• AC Welder with Reduced Voltage Control.
1.c. In semiautomatic or automatic wire welding, the electrode, electrode reel,
welding head, nozzle or semiautomatic welding gun are also electrically
"hot".
1.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.
1.e. Ground the work or metal to be welded to a good electrical (earth) ground.
1.f. Maintain the electrode holder, work clamp, welding cable and welding machine
in good, safe operating condition. Replace damaged insulation.
1.g. Never dip the electrode in water for cooling.
1.h. Never simultaneously touch electrically "hot" parts of electrode holders con-
nected to two welders because voltage between the two can be the total of
the open circuit voltage of both welders.
1.i. When working above floor level, use a safety belt to protect yourself from a fall
should you get a shock.
1.j. Also see Items 4.c. and 6.
2.b. Use suitable clothing made from durable flame-resistant material to
protect your skin and that of your helpers from the arc rays.
2.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 metal.
ELECTRIC SHOCK
1.a. The electrode and work (or ground) circuits are electrically
"hot" when the welder is on. Do not touch these "hot" parts with
your bare skin or wet clothing. Wear dry, hole-free gloves to
insulate hands.
1.b. Insulate yourself from work and ground using dry insula-
tion. Make certain the insulation is large enough to cover your
ARC RAYS
2.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. Headshield
and filter lens should conform to ANSI Z87. I standards.
