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, hearing aids, or other electronic health
equipment. Persons who work near plasma arc cutting
applications should consult their medical health profes-
sional 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 us-
ing 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 chlori-
nated solvents and cleansers. Remove all sources of these va-
pors.
• This product, when used for welding or cutting, produces fumes
or gases which contain chemicals known to the State of Califor-
nia 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 pro-
duces high voltage electrical energy. This electric energy can cause se-
vere 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 service or re-
pairs.
• Read and follow all the instructions in the Operating Manual.
FIRE AND EXPLOSION
Fire and explosion can be caused by hot slag, sparks, or the plasma arc.
• Be sure there is no combustible or flammable material in the
workplace. Any material that cannot be removed must be pro-
tected.
• Ventilate all flammable or explosive vapors from the workplace.
• Do not cut or weld on containers that may have held combus-
tibles.
