WARNING
OPERATION AND
MAINTENANCE OF ARC
WELDING EQUIPMENT CAN BE
DANGEROUS AND HAZARDOUS
TO YOUR HEALTH.
To prevent possible injury, read,
understand and follow all warnings,
safety precautions and instructions
before using the equipment. Call 1-
800-462-2782 or your local distributor
if you have any questions.
GASES AND FUMES
Gases and fumes produced during the Arc
welding/cutting process can be dangerous and
hazardous to your health.
• Keep all fumes and gases from the breathing
area. Keep your head out of the welding
fume plume.
• Use an air-supplied respirator if ventilation is
not adequate to remove all fumes and gases.
• The kinds of fumes and gases from the arc
welding/cutting depend on the kind of
metal being used, coatings on the metal, and
the different processes. You must be very
careful when cutting or welding any metals
which may contain one or more of the
following:
Antimony Chromium Mercury
Arsenic Cobalt Nickel
Barium Copper Selenium
Beryllium Lead Silver
Cadmium Manganese
Vanadium
• Always read the Material Safety Data Sheets
(MSDS) that should be supplied with the
material you are using. These MSDSs will
give you the information regarding the kind
and amount of fumes and gases that may be
dangerous to your health.
• For information on how to test for fumes and
gases in your workplace, refer to item 1 in
Subsection 1.03, Publications in this manual.
• Use special equipment, such as water or
down draft welding/cutting tables, to
capture fumes and gases.
• Do not use the welding torch in an area
where combustible or explosive gases or
materials are located.
• Phosgene, a toxic gas, is generated from the
vapors of chlorinated solvents and cleansers.
Remove all sources of these vapors.
ELECTRIC SHOCK
Electric Shock can injure or kill. The arc welding
process uses and produces high voltage electrical
energy. This electric energy can cause severe or
fatal shock to the operator or others in the
workplace.
• Never touch any parts that are electrically
“live” or “hot.”
• Wear dry gloves and clothing. Insulate
yourself from the work piece or other parts
of the welding circuit.
• Repair or replace all worn or damaged parts.
• Extra care must be taken when the workplace
is moist or damp.
