WARNINGS & SAFEGUARDS FOR
WELDING & CUTTING OPERATIONS
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 and the power source manual used with this equipment. 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 instructions 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 service 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 in 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 part 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 no par t of the electrode circuit is touching the work or
ground to prevent accidental contact. Never immerse Mig-Guns, Electrode Holders, Tig Torches, Plasma Torches, or
Electrodes in water for cooling.

SMOKE, FUMES, AND GASES CAN BE DANGEROUS TO YOUR HEALTH
Keep smoke, fumes, and gases from your breathing zone and the general area. Smoke, fumes, and gases
from the welding or cutting process are of various types and strengths, depending on the kind of base metal
being welded on. To ensure your safety, do not breath these fumes or gases. Ventilation must be adequate to
remove smoke, fumes, and gases during the welding procedure to protect operators and others in the immediate area.
Do not weld in locations where chlorinated hydrocarbon vapors are coming from degreasing, cleaning, or spraying
operations. Vapors of chlorinated solvents can form the toxic gas “phosgene” when exposed to ultraviolet radiation from an
electric arc. All solvents, degreasers, and potential sources of these vapors must be removed from the welding area.
Shielding gases used for arc welding can displace air and cause injury or death. Fumes produced by welding or cutting,
especially in confined areas, can cause discomfort and physical harm if inhaled over an extended period of time.
Always provide adequate ventilation in the welding and cutting area to insure breathing air is safe. Use air-supplied
respirators if ventilation is not adequate to remove all fumes and gases. Never Ventilate with Oxygen, because oxygen
supports and vigorously accelerates fire.
