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.
- Ensure that mask is fitted with appropriate shade lens as well as with safety plate.
- 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 10 m 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 6 mm stick out after welding.
Hot Materials
CAUTION!
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.
Sparks/Flying Debris
CAUTION!
Welding creates hot sparks that can cause injury. Chipping slag off welds creates flying debris.
- Wear protective apparel at all times: safety shield, welder’s mask (helmet) and ear plugs to prevent spark
injuries of your eyes, face, ears and hair.
Electromagnetic Field
CAUTION!
- Electromagnetic fields can interfere with various electrical and electronic devices such as
pacemakers.
- Consult your doctor before using any electric arc welder or cutting device
- Keep people with pacemakers away from your welding area when welding.
