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 pacemak-
ers, hearing aids, or other electronic health
equipment. Persons who work near plasma
arc cutting applications should consult their
medical health professional and the manu-
facturer 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 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,
produces fumes or gases which contain chemicals
known to the State of California to cause birth de-
fects 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
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.
• Install and maintain equipment according to NEC
code, refer to item 9 in Subsection 1.03, Publica-
tions.
• Disconnect power source before performing any
service or repairs.
• Read and follow all the instructions in the Operating
Manual.
