IMPORTANT - PROTECT YOURSELF AND OTHERS!
REMEMBER THAT SAFETY DEPENDS ON YOU.
The operator, supervisor, and helper must read and understand all warning and safety information provided in these
instructions. Serious injury or death could result if welding and cutting equipment is not properly installed, used, and
maintained. Training and proper supervision are most important for a safe work place. Installation, operation, repair work, and
maintenance must be performed by qualified personnel. Retain these instr uctions for future use. Additional recommended safety
and operating information is referenced in each section.
ELECTRICAL SHOCK CAN CAUSE INJURY OR DEATH
Electrical equipment must be installed and maintained in accordance with the National Electrical Code, NFPA 70, and all local codes. Maintain Mig-
Guns, Electrode Holders, Tig Torches, Plasma Torches, Work Clamp, Welding Cable, and Welding Machines in good, safe operating condition. Replace
worn or damaged insulation. Do not try to repair or service equipment while the power is still on. Do not ser vice or repair equipment unless you are
trained and qualified to do so. The Electrode and Work (or Ground) circuits are electrically “HOT” when equipment power is on. At no time should you touch the
Electrode and Electrical Ground at the same time with bare skin or wet clothing while the power is on. Insulate yourself from work and ground using dry insulation.
When welding in damp locations make certain the insulation is large enough to cover your full area of physical contact with work and ground. Ground the work (metal
to be welded) to a good electrical earth ground. Keep gas cylinders, chains, wire ropes, hoists, cranes, and elevators away from any par t of the electrical path.
Always be sure the work cable makes a good electrical connection with the metal being welded. Occasionally check all ground connections to determine if they are
mechanically strong and electrically adequate for the current required. The ground connection should be as close as possible to the area being welded. Never touch
electrically “HOT” parts of electrode holders connected to two welding power sources at the same time. The voltage between the two can be the total of the open
circuit voltage of both power sources. When the welding or cutting process requires values of open circuit voltages in alternating current machines higher than 80
volts, and direct current machines higher than 100 volts, adequate insulation or other means must be provided to prevent the operator from making accidental contact
with the high voltage. The use of reliable automatic controls for reducing no load voltage is recommended to reduce shock hazard. When not welding for any
substantial period of time, make certain that no par t of the electrode circuit will accidentally make contact with the work or ground. Never immerse Mig-Guns,
Electrode Holders, Tig Torches, Plasma Torches, or Electrodes in water for cooling.
