• Do not weld, cut, or perform other such work on used barrels, drums, tanks, or other containers that had a
flammable or toxic substance. The techniques for removing flammable substance and vapors, to make a used
container safe for welding or cutting, are quite complex and require special education and training.
• Do not cut in atmospheres containing flammable dust or vapors.
• Do not cut pressurized cylinders, pipes, or vessels.
• Do not cut containers that have held combustibles.
• Do not wear gloves or other clothing that contains oil, grease, or other flammable substances.
• Do not wear flammable hair preparations
• Have fire extinguisher equipment handy for immediate use. A portable chemical fire extinguisher, type ABC, is
recommended.
• Make sure the work area has a good, solid, safe floor, preferably concrete or masonry, not tiled, carpeted, or
made of any other flammable material.
• Protect flammable walls, ceilings, and floors with heat resistant covers or shields.
• Check work area to make sure it is free of sparks, glowing metal or slag, and flames before leaving the work
area.
• Wear garments free of oil or other flammable substances such as leather gloves, thick cotton shirts with no
synthetic materials, cuff-less trousers, closed toed shoes. Keep long hair pulled back.
• Remove any combustibles such as lighters and matches before doing any welding or cutting.
• Follow requirements in OSHA and NFPA for hot work and have an extinguisher nearby
ELECTRIC SHOCK CAN KILL.
PLASMA TORCH (9) and work circuit are electrically live whenever the output is on. The input power circuit and
machine internal circuits are also live when POWER SWITCH (2) is ON. Plasma arc cutting requires higher voltages
than welding to start and maintain the arc (200 to 400 volts DC are common). It also uses torches designed with
safety interlock systems which turn off the machine when the SHIELD CUP (E) is loosened or if the CUTTING TIP (D)
touches the ELECTRODE (B) during operation. Incorrectly installed or improperly grounded equipment is a hazard.
• Do not, in any manner, come into physical contact with any part of the cutting current circuit. The cutting current
circuit includes:
a. the workpiece or any conductive material in contact with it,
b. the GROUND CLAMP,
c. the ELECTRODE or CUTTING
• Do not cut in a damp area or come in contact with a moist or wet surface.
• Do not attempt to cut if any part of clothing or body is wet.
• Do not allow the cutting equipment to come in contact with water or moisture.
• Do not drag cables or PLASMA TORCH through or allow them to come into contact with water or moisture.
• Do not touch the machine or attempt to turn the machine ON or OFF if any part of the body or clothing is moist
or if you are in physical contact with water or moisture.
• Do not attempt to plug the machine into input power if any part of body or clothing is moist, or if you are in
physical contact with water or moisture.
• Do not connect GROUND CLAMP to or cut on electrical conduit.
• Do not alter INPUT POWER CABLE (3) or plug in any way.
• Do not attempt to plug the machine into input power if the ground prong on power cable plug is bent over,
broken off, or missing.
• Do not allow the machine to be connected to input power or attempt to cut if the machine, cables, or cutting site
are exposed to any form of atmospheric precipitation, or salt water spray.
• Do not carry coiled cables around shoulders, or any other part of the body, when they are plugged into the
machine.
• Do not modify any wiring, ground connections, switches, or fuses in this cutting equipment.
• Wear welding gloves to help insulate hands from cutting circuit.
• Keep all liquid containers far enough away from the plasma cutting machine and work area so that if spilled,
the liquid cannot possibly come in contact with any part of the machine or electrical cutting circuit.
• Replace any cracked or damaged parts that are insulated or act as insulators such as cables or PLASMA
TORCH immediately.
Touching live electrical parts can cause fatal shocks or severe burns. The
