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.
1-2
SET-UP AND SAFE OPERATING PROCEDURES
89200016Safety Precautions
ARC RAYS, HOT SLAG, AND SPARKS CAN INJURE EYES AND BURN SKIN
Welding and cutting processes produce extreme localized heat and strong
ultraviolet rays. Never attempt to weld/cut without a federally compliant welding
helmet with the proper lens. A number 12 to 14 shade filter lens provides the
best protection against arc radiation. When in a confined area, prevent the
reflected arc rays from entering around the helmet. Approved shielding curtains
and appropriate goggles should be used to provide protection to others in the surrounding area.
Skin should be protected from arc rays, heat, and molten metal. Always wear protective gloves
and clothing. All pockets should be closed and cuffs sewn shut. Leather aprons, sleeves, leggings,
etc. should be worn for out-of-position welding and cutting, or for heavy operations using large
electrodes. Hightop work shoes provide adequate protection from foot burns. For added protection,
use leather spats. Flammable hair preparations should not be used when welding/cutting. Wear
ear plugs to protect ears from sparks. Where work permits, the operator should be enclosed in
an individual booth painted with a low reflective material such as zinc oxide. See safety and
operating references 1, 2, and 3.
WELDING SPARKS CAN CAUSE FIRES AND EXPLOSIONS
Combustibles reached by the arc, flame, flying sparks, hot slag, and heated
materials can cause fire and explosions. Remove combustibles from the work
area and/or provide a fire watch. Avoid oily or greasy clothing as a spark may
ignite them. Have a fire extinguisher nearby, and know how to use it. If welding/
cutting is to be done on a metal wall, partition, ceiling, or roof, precautions must
be taken to prevent ignition of nearby combustibles on the other side. Do not
weld/cut containers that have held combustibles. All hollow spaces, cavities, and containers
should be vented prior to welding/cutting to permit the escape of air or gases. Purging with inert
gas is recommended. Never use oxygen in a welding torch. Use only inert gases or inert gas
mixes as required by the process. Use of combustible compressed gases can cause explosions
resulting in personal injury or death. Arcing against any compressed gas cylinder can cause
cylinder damage or explosion. See safety and operating references 1, 2, 5, 7, and 8.
NOISE CAN DAMAGE HEARING
Noise from the air carbon-arc process can damage your hearing. Wear protective
hearing devices to ensure protection when noise levels exceed OHSA standards.
Adequate hearing protection devices must be worn by operators and surrounding
personnel to ensure personal protection against noise. See safety and operating
references 1, 2, and 6.

California to cause birth defects and other reproductive harm. Wash hands after
