GENERAL SAFETY INSTRUCTION

UV and IR Arc Rays
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
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.
-Wear garments that are oil-free with no pockets or cuffs that will collect sparks.
-Do not have on your person any items that are combustible, such as lighters or
matches.
-Keep work lead connected as close to the weld area as possible to prevent any
unknown, unintended paths of electrical current from causing electrical shock
and fire hazards.
-To prevent any unintended arcs, cut wire back to ¼" stick out after welding.
Hot Materials
Welded materials are hot and can cause severe burns if handled
improperly.
-Do not touch welded materials with bare hands.
-Do not touch MIG gun nozzle after welding until it has had time to cool down.
