Safety Precautions
SECTION 1:
SAFETY PRECAUTIONS
WARNING
SERIOUS INJURY OR DEATH
may result if welding and cutting equipment is not
properly installed, used, and maintained. Misuse of this equipment and other
unsafe practices can be hazardous. The operator, supervisor, and helper must read
and understand the following safety warnings and instructions before installing
or using any welding or cutting equipment, and be aware of the dangers of the
welding or cutting process. Training and proper supervision are important for a
safe work place. Keep these instructions for future use. Additional recommended
safety and operating information is referenced in each section.
ELECTRIC SHOCK CAN CAUSE INJURY OR DEATH
Install and maintain equipment in accordance with the National Electrical Code
(NFPA 70) and local codes.
Do not
service or repair equipment with power ON.
Do not
operate equipment with protective insulators or covers removed. Service
or repair to equipment must be done by qualified and/or trained personnel only.
Do not
contact electrically live parts.
Always
wear dry welding gloves that are in
good condition. Aluminized, protective clothing can become part of the electrical path. Keep oxygen
cylinders, chains, wires, ropes, cranes, and hoists away from any part of the electrical path. All
ground connections must be checked periodically to determine if they are mechanically strong,
and electrically adequate for the required current. When engaged in AC welding/cutting under
wet conditions or where perspiration is a factor, the use of automatic controls for reducing the
no load voltage is recommended to reduce shock hazards. Accidental contact must be prevented
when using open circuit voltage exceeding 80 volts AC, or 100 volts DC by adequate insulation
or other means. When welding is to be suspended for any length of time, such as during lunch or
overnight, all electrode holders and electrodes should be removed from the electrode holder and
the power supply should be turned OFF to prevent accidental contact. Keep MIG-Guns, electrode
holders, Tig torches, Plasma torches, and electrodes away from moisture and water.
See safety
and operating references 1, 2, and 8.
SMOKE, FUMES, AND GASES CAN BE DANGEROUS TO YOUR HEALTH
Ventilation must be adequate to remove smoke, fumes, and gases during
operation to protect operators and others in the area. 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 operating area. Use air-supplied respirators
if ventilation is not adequate to remove all fumes and gases. Oxygen supports, and vigorously
accelerates fire and should
never
be used for ventilation.
See safety and operating references
1, 2, 3, and 4.
