ELECTRIC SHOCK
can kill.
1.a. The electrode and work (or ground) circuits
are electrically “hot” when the welder or cutter
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 insulation.
Make certain the insulation is large enough to cover your full
area of physical contact with work and ground.
In addition to the normal safety precautions, if welding or
cutting must be performed 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 or cutting
cable and
welding or cutting 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 connected 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.
PROTECT YOURSELF AND OTHERS FROM POSSIBLE SERIOUS INJURY OR DEATH. KEEP CHILDREN
AWAY. PACEMAKER WEARERS SHOULD CONSULT WITH THEIR DOCTOR BEFORE OPERATING.
Read and understand the following safety highlights. For additional safety information, it is strongly recommended that you pur-
chase a copy of “Safety in Welding & Cutting - ANSI Standard Z49.1” from the American Welding Society, P.O. Box 351040,
Miami, Florida 33135 or CSA Standard W117.2-1974. A Free copy of “Arc Welding Safety” booklet E205 is available from the
Lincoln Electric Company, 22801 St. Clair Avenue, Cleveland, Ohio 44117-1199.
BE SURE THAT ALL INSTALLATION, OPERATION, MAINTENANCE AND REPAIR PROCEDURES ARE PER-
FORMED ONLY BY QUALIFIED INDIVIDUALS.
ARC RAYS can burn.
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 cutting or
observing open arc welding or cutting.
Headshield and filter lens should conform to
ANSI Z87. I standards.
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.
CUTTING can be hazardous.
FUMES AND GASES
can be dangerous.
3.a. Welding or cutting may produce fumes and
gases hazardous to health. Avoid breathing
these fumes and gases.When welding,
or cutting keep your head out of the fume.
Use enough
ventilation and/or exhaust at the
arc to keep
fumes and gases away from the
breathing zone. When welding or cut-
ting with electrodes which require special ventilation such as
stainless or hard facing (see instructions on container or
MSDS) or on lead or cadmium plated steel and other metals
or coatings which produce highly toxic fumes, keep exposure
as low as possible and below Threshold Limit Values (TLV)
using local exhaust or mechanical ventilation. In confined
spaces or in some circumstances, outdoors, a respirator may
be required. Additional precautions are also required when
welding on galvanized steel.
3.b.
Do not weld or cut in locations near chlorinated hydrocarbon
vapors coming from degreasing, cleaning or spraying
operations. The heat and rays of the arc can react with
solvent vapors
to
form phosgene, a highly toxic gas, and
other irritating products.
3.c. Shielding gases used for arc welding or cutting can displace
air and cause injury or death. Always use enough ventilation,
especially in confined areas, to insure breathing air is safe.
3.d. Read and understand the manufacturer’s instructions for this
equipment and the consumables to be used, including the
material safety data sheet (MSDS) and follow your
employer’s safety practices. MSDS forms are available from
your welding distributor or from the manufacturer.
3.e. Also see item 7b.
