1.02 Important Safety Precautions
!
WARNING
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, hear-
ing aids, or other electronic health equipment.
Persons who work near plasma arc cutting ap-
plications 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 cut-
ting 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 Sub-
section 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 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.
