MIG 140 INVERTER WELDER 058-9305-6
•
Risk for breathing: Never directly inhale the emission of harmful fumes
during welding. Make sure the work area is clean, dry and ventilated. Use a
ventilation device to remove welding fumes from the work environment.
•
Do not weld on coated materials like galvanized, cadmium plated or
contacting zinc, mercury, or barium, as they emit harmful fumes that are
dangerous to breathe. If required, use a respirator with air supply or remove
coating from the material in the weld area.
•
Do not weld near materials that will emit toxic fumes when heated. Vapours
from cleaners, sprays, and degreasers can be highly toxic when heated.
•
Risk of fire: Do not weld on containers or pipes that contain flammable,
gaseous, or liquid combustibles.
Welding creates sparks and heat that ignite
flammable and explosive materials. Remove all flammable materials within
35 feet of the welding arc or tightly cover the flammable materials with
fireproof covers. Ensure that flying sparks do not cause fires or explosions in
hidden areas, cracks or areas that are out of vision. Use a fire extinguisher in
the work area.
Do not have any items that are combustible, such as lighters
or matches
•
Connect the work lead to the weld area as close as possible to prevent any
unknown, unintended paths of electrical current from causing electrical
shock and fire hazards. To prevent any unintended arcs after welding, cut off
the excess wire that extends past the end of the nozzle more than ¼"
.
•
Risk of burns: Do not touch the welded materials with bare hands, as the
welded materials are hot and can cause severe burns. Do not touch MIG gun
nozzle or tip of the electrode holder after welding until it has been cooled.
•
Wear garments that are oil
-
free with no pockets or cuffs that will collect
sparks.
•
Risk of UV and IR arc rays:
Do not look at the welding arc without proper eye
protection, as the welding arc produces ultraviolet (UV) and infrared (IR) rays.
Use shields that adheres to ANSI Z87.1. For welders under 160 A output, use
a shade 10 lens; for above 160 A, use a shade 12 lens.
Wear flame
retardant clothes, leather shirts, pants or shoes to cover the bare skin from
the arc.
•
Use appropriate shield to prevent other personnel from being affected by
harmful rays.
