1.02 Important Safety Precautions
WARNINGS
OPERATION AND MAINTENANCE OF
PLASMA ARC EQUIPMENT CAN BE DAN-
GEROUS 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 exists.
To prevent possible injury, read, understand and
follow all warnings, safety precautions and in-
structionsbeforeusing the equipment. Call1-603-
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
onthe metal, and thedifferent processes. You must
be very careful when cutting or welding any met-
als which may contain one or more of the follow-
ing:
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 in-
formationregarding the kind andamountof fumes
and gases that may be dangerous to your health.
• For information on how to test for fumes and gases
inyourworkplace,refertoitem1inSubsection1.03,
Publications in this manual.
• Usespecialequipment,suchas 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 op-
erator or others in the workplace.
• Never touch any parts that are electrically “live”
or “hot.”

GENERAL INFORMATION 1-2 Date: November 15, 2001
• 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 Operat-
ing 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 ma-
terial in the workplace. Any material that cannot
be removed must be protected.
• Ventilate all flammable or explosive vapors from
the workplace.
• Do not cut or weld on containers that may have
held combustibles.
• Provideafirewatchwhen working in an areawhere
fire hazards may exist.
• Hydrogen gas may be formed and trapped under
aluminum workpieces when they are cut under-
water or while using a water table. DO NOT cut
aluminum alloys underwater or on a water table
unless the hydrogen gas can be eliminated or dis-
sipated. Trapped hydrogen gas that is ignited will
cause an explosion.
NOISE
Noisecan cause permanent hearing loss. Plasma arcpro-
cesses can cause noise levels to exceed safe limits. You
must protect your ears from loud noise to prevent per-
manent loss of hearing.
• To protect your hearing from loud noise, wear pro-
tective ear plugs and/or ear muffs. Protect others
in the workplace.
• Noiselevelsshouldbemeasuredto be surethe deci-
bels (sound) do not exceed safe levels.
• For information on how to test for noise, see item 1
in Subsection 1.03, Publications, in this manual.
PLASMAARC RAYS
PlasmaArcRays can injureyour eyes and burn your skin.
The plasma arc process produces very bright ultra violet
and infra red light. These arc rays will damage your
eyesandburnyourskinifyouarenot properlyprotected.
• To protect your eyes, always wear a welding hel-
metor shield. Also always wear safety glasseswith
side shields, goggles or other protective eye wear.
• Wear welding gloves and suitable clothing to pro-
tect your skin from the arc rays and sparks.
• Keep helmet and safety glasses in good condition.
Replace lenses when cracked, chipped or dirty.
• Protect others in the work area from the arc rays.
Use protective booths, screens or shields.
• Use the shade of lens as suggested in the following
per ANSI/ASC Z49.1:
Minimum Protective Suggested
Arc Current Shade No. Shade No.
Less Than 300* 8 9
300 - 400* 9 12
400 - 800* 10 14
* Thesevalues apply wheretheactual arcisclearly
seen. Experience has shown that lighter filters
may be used when the arc is hidden by the work-
piece.

(La sécurité de santé en Californie et la code sécurité
Sec. 25249.5 et seq.)
CHOC ELECTRIQUE
Les chocs électriques peuvent blesser ou même tuer. Le
procédé au jet de plasma requiert et produit de l’énergie
électrique haute tension. Cette énergie électrique peut
produire deschocsgraves,voiremortels, pour l’opérateur
et les autres personnes sur le lieu de travail.
• Netouchezjamais une pièce “sous tension” ou “vive”;
portez des gants et des vêtements secs. Isolez-vous
de la pièce de travail ou des autres parties du circuit
de soudage.
• Réparez ou remplacez toute pièce usée ou
endommagée.
• Prenez des soins particuliers lorsque la zone de tra-
vail est humide ou moite.
