Operators Manual
3
•
Work only in a well-ventilated area or use a ventilation device to remove welding
fumes from the environment where you will be working
•
Do not weld on coated materials (galvanized, cadmium plated or containing zinc,
mercury or barium). They will emit harmful fumes that are dangerous to breathe. If
necessary use a ventilator, respirator with air supply or remove the coating from the
material in the weld area
•
The fumes emitted from some metals when heated are extremely toxic. Refer to the
material safety data sheet for the manufacturer’s instructions
•
Do not weld near materials that will emit toxic fumes when heated. Vapors from
cleaners, sprays and degreasers can be highly toxic when heated
UV and IR Arc Rays
DANGER!
The welding arc produces ultraviolet (UV) and infrared (IR) rays that can cause
injury to your eyes and skin. Do not look at the welding arc without proper eye protection.
•
Always use a helmet that covers your full face from the neck to top of head and to the
back of each ear
•
Use a lens that meets ANSI standards and safety glasses. For welders under 160 Amps
output, use a shade 10 lens; for above 160 Amps, use a shade 12. Refer to the ANSI
standard Z87.1 for more information
•
Cover all bare skin areas exposed to the arc with protective clothing and shoes. Flame-
retardant cloth or leather shirts, coats, pants or coveralls are available for protection
•
Use screens or other barriers to protect other people from the arc rays emitted from
your welding
•
Warn people in your welding area when you are going to strike an arc so they can
protect themselves
Fire Hazards
WARNING!
Do not weld on containers or pipes that contain or have had flammable,
gaseous or liquid combustibles in them. Welding creates sparks and heat that can ignite
flammable and explosive materials.
•
Do not operate any electric arc welder in areas where flammable or explosive
materials are present
•
Remove all flammable materials within 35 feet of the welding arc. If removal is not
possible, tightly cover them with fireproof covers
•
Take precautions to ensure that flying sparks do not cause fires or explosions in hidden
areas, cracks or areas you cannot see
•
Keep a fire extinguisher close in the case of fire
