MIG WELDING GUN OPERATION MANUAL
2.0 SAFETY PRECAUTIONS
WARNING
Improper installation, use or maintenance of welding equipment may cause serious injury or death.
All operators must read and understand all safety warnings and instructions before installing or using
this welding gun. All operators must be trained in proper welding safety and operation procedures
prior to operating this welding gun.
Please keep these instructions for future reference.
WARNING: ELECTRIC SHOCK HAZARD
Operators should always wear dry welding gloves and protective clothing when welding. Do not
contact electrically live parts. Keep welding guns and other welding equipment away from moisture
and water. Ensure ground connections are secure and compatible with the required electric current.
When welding under wet conditions or where perspiration is a factor, the use of automatic controls
for reducing the no load voltage is recommended to reduce the risk of electric shock. Accidental
contact must be prevented with open circuit voltage exceeding 80 volts AC, or 100 volts DC by
using insulation or other means. When welding gun is not in use, turn off power supply to prevent
any accidental contact.
Welding equipment should be installed and maintained in accordance with National Electrical Code
(NFPA 70) and in compliance with local codes. Equipment should only be serviced by qualified or
trained personnel only. Do not disassemble torch or change welding consumables with the power
supply on. See welding safety and operating references in section 2.1 for safety guidelines and
additional information.
WARNING: ARC RAYS AND SPARKS CAN CAUSE EYE INJURY AND BURNS
Always wear a federally compliant welding helmet with the proper lens when welding, along with
protective welding gloves and protective clothing. Protective clothing should cover all exposed skin
to prevent burns and exposure to ultraviolet rays. An approved welding curtain or solid wall must
be used in areas where other personnel may be exposed to arc rays. Other personnel in the work
area exposed to arc rays and sparks must also wear a welding helmet and protective clothing to
prevent eye injury and burns. Ear plugs should be worn to protect ears from sparks. Avoid using
flammable hair preparations when welding.
Never attempt to weld without a welding helmet,
protective gloves and clothing.
See welding safety and operating references in section 2.1 for
safety guidelines and additional information.
WARNING: WELDING SPARKS CAN CAUSE FIRES AND EXPLOSIONS
All combustible materials should be removed from the work area (at least 35 ft / 10.7 m) to prevent
fires and explosions. Do not wear clothing soaked with oils, gasoline or other flammable liquids
while welding. Always keep a fire extinguisher near the work area and understand its operation.
Do not weld containers that have contained flammable materials or liquids. Use only inert gases or
inert gas mixes required for the welding process. Do not use oxygen with a welding torch. Arcing
against compressed gas cylinders may cause damage to the cylinder or explosion. See welding
safety and operating references in section 2.1 for safety guidelines and additional information.
WARNING: SMOKE AND FUMES CAN BE DANGEROUS TO YOUR HEALTH
Ensure there is adequate ventilation to remove smoke and fumes from the work area to protect
operators and other nearby personnel. Avoid using chlorinated solvents in the work area that can
form Phosgene when exposed to UV arc radiation. An air supplied respirator must be worn where
ventilation is not adequate to remove fumes and vapors. Do not use oxygen for ventilation in the
work area. See welding safety and operating references in section 2.1 for safety guidelines and
additional information.
