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. Persons who work near
plasma arc cutting applications should consult their
medical health professional and the manufacturer of the
health equipment to determine whether a hazard exists.
To prevent possible injury, read, understand
and follow all warnings, safety precautions and
instructions 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 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 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 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
cutting tables, to capture fumes and gases.
• Do not use the plasma 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.
• WARNING: This product contains chemicals, including
lead, known to the State of California to cause birth
defects and other reproductive harm. Wash hands after
handling.
ELECTRIC SHOCK
Electric Shock can injure or kill. The plasma arc process uses
and produces high voltage electrical energy. This electric en-
ergy 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.
