1.02 Important Safety Precautions
WARNINGS
OPERATION AND MAINTENANCE OF PLASMA
ARC EQUIPMENT CAN BE DANGEROUS AND
HAZARDOUS TO YOUR HEALTH.
Plasma arc cutting produces intense electric and
magnetic emissions that may interfere with the
proper function of cardiac pacemakers, hearing
aids, or other electronic health equipment. Per-
sons who work near plasma arc cutting applica-
tions should consult their medical health profes-
sional and the manufacturer of the health
equipment to determine whether a hazard ex-
ists.
To prevent possible injury, read, understand and
follow all warnings, safety precautions and instruc-
tions before using the equipment. Call 1-603-
298-5711 or your local distributor if you have any
questions.
GASES AND FUMES
Gases and fumes produced during the plasma cutting pro-
cess 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 ad-
equate to remove all fumes and gases.
• The kinds of fumes and gases from the plasma arc
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 us-
ing. These MSDSs will give you the information re-
garding 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, Pub-
lications in this manual.
• Use special equipment, such as water or down draft
cutting tables, to capture fumes and gases.
• Do not use the plasma torch in an area where com-
bustible 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.
• This product, when used for welding or cutting, pro-
duces fumes or gases which contain chemicals known
to the State of California to cause birth defects and, in
some cases, cancer. (California Health & Safety Code
Sec. 25249.5 et seq.)
ELECTRIC SHOCK
Electric Shock can injure or kill. The plasma arc process
uses and produces high voltage electrical energy. This elec-
tric 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.
• Install and maintain equipment according to NEC code,
refer to item 9 in Subsection 1.03, Publications.
• Disconnect power source before performing any ser-
vice or repairs.
• Read and follow all the instructions in the Operating
Manual.
