GENERAL INFORMATION 1-2 Manual 0-5056
• 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 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 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 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, Publications.
• Disconnect power source before performing any service or repairs.
• 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 protected.
• Ventilate all flammable or explosive vapors from the workplace.
• Do not cut or weld on containers that may have held combustibles.
• Provide a fire watch when working in an area where fire hazards may exist.
• Hydrogen gas may be formed and trapped under metal work pieces when they are cut underwater or while
using a water table. DO NOT cut underwater or on a water table unless the hydrogen gas can be eliminated or
dissipated. Trapped hydrogen gas that is ignited will cause an explosion.
• Aluminum fumes (made of ultra fine aluminum solid particles) maybe formed and trapped under aluminum
work pieces when they are cut underwater or while using a water table. DO NOT cut aluminum alloys underwa-
ter or on a water table unless the aluminum fumes can be eliminated or dissipated. Trapped aluminum fume that
readily and violently reacts with water will cause an explosion.
