PLASMA CUTTING SERIES EQUIPMENT
WARNING
PROTECT YOURSELF AND OTHERS FROM POSSIBLE SERIOUS INJURY OR DEATH.
KEEP CHILDREN AWAY. PACEMAKER WEARERS KEEP AWAY UNTIL CONSULTING
YOUR DOCTOR. DO NOT LOSE THESE INSTRUCTIONS. READ OPERATING/INSTRU-
CTION MANUAL BEFORE INSTALLING, OPERATING OR SER ICING THIS EQUIPMENT.
Welding products and welding processes can cause serious injury or death, or damage
to other equipment or property, if the operator does not strictly observe all safety rules
and take precautionary actions.
Safe practices have developed from past experience in the use of welding and cutting.
These practices must be learned through study and training before using this equipment.
Some of these practices apply to equipment connected to power lines; other practices
apply to engine driven equipment. Anyone not having extensive training in welding and
cutting practices should not attempt to weld.
Safe practices are outlined in the European Standard EN60974-1 entitled: Safety in
welding and allied processes Part 2: Electrical HAVE ALL INSTALLATION, OPERATION,
MAINTENANCE, ANDREPAIR WORK PERFORMED ONLY BY QUALIFIED PEOPLE.
1.1 Arc welding damage
ARNING
ELECTRIC SHOCK can kill.
Touching live electrical parts can cause fatal shocks or severe burns. The electrode and
work circuit is electrically live whenever the output is on. The input power circuit and
machine internal circuits are also live when power is on. In semi-automatic or automatic
wire welding, the wire, wire reel, drive roll housing, and all metal parts touching the welding
wire are electrically live. Incorrectly installed or improperly grounded equipment is a hazard.
1. Do not touch live electrical parts.
2. Wear dry, hole-free insulating gloves and body protection.
3. Insulate yourself from work and ground using dry insulating mats or covers.
4. Disconnect input power or stop engine before installing or servicing this equipment.
Lock input power disconnect switch open, or remove line fuses so power cannot be
turned on accidentally.
5. Properly install and ground this equipment according to its Owner's Manual.

ARC RAYS can burn eyes and skin,
ARNING
NOISE can damage hearing.
Arc rays from the welding process produce intense heat and strong ultraviolet rays that
can burn eyes and skin. Noise from some processes can damage hearing.
1. Wear a welding helmet fitted with a proper shade of filter to protect your face and eyes
when welding or watching;
2. Wear approved safety glasses. Side shields recommended;
3. Use protective screens or barriers to protect others from flash and glare;
warn others not to watch the arc;
4. Wear protective clothing made from durable, flame-resistant material(wool and leather)
and foot protection;
5. Use approved ear plugs or ear muffs if noise level is high;
6. Never wear contact lenses while welding.
FUMES AND GASES can be hazardous
ARNING
to your health.
Welding produces fumes and gases. Breathing these fumes and gases can be hazardous
to your health.
1. Keep your head out of the fumes. Do not breathe the fumes.
2. If inside, ventilate the area and/or use exhaust at the arc to remove welding fumes
and gases.
3. If ventilation is poor, use an approved air-supplied respirator.
4. Work in a confined space only if it is well ventilated, or while wearing an air-supplied
respirator. Shielding gases used for welding can displace air causing injury or death.
Be sure the breathing air is safe.
5. Do not weld in locations near degreasing, cleaning, or spraying operations. The heat
and rays of the arc can react with vapours to form highly toxic and irritating gases.
6. Do not weld on coated metals, such as galvanized, lead, or cadmium plated steel, unless
the coating is removed from the weld area, the area is well ventilated, and if necessary,
while wearing an air- supplied respirator. The coatings and any metals containing these
elements can give off toxic fumes if welded.
ARNING WELDING can cause fire or explosion.
Sparks and spatter fly off from the welding arc. The fly sparks and hot metal, weld spatter,
hot workpiece, and hot equipment can cause fires and burns. Accidental contact of
electrode or welding wire to metal objects can cause sparks, overheating, or fire.
1. Protect yourself and others from flying sparks and hot metal.
2. Do not weld where flying sparks can strike flammable material.
3. Remove all flammables far away from the welding arc. If this is not possible, tightly
cover them with approved covers.
4. Be alert that welding sparks and hot materials from welding can easily go through small
cracks and openings to adjacent areas.
5. Watch for fire, and keep a fire extinguisher nearby.
