- 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
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 standards and safety glasses.
- 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 10 metres 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.
- Connect ground lead as close to the area being welded as possible to ensure a good
ground.
- Do not allow any body part to come in contact with the welding wire if you are in
contact with the material being welded, ground or electrode from another welder.
- Do not weld if you are in an awkward position. Always have a secure stance while
welding to prevent accidents. Wear a safety harness if working above ground.
- Do not drape cables over or around your body.
- Wear a full coverage helmet with appropriate shade (see ANSI Z87.1 safety standard)
and safety glasses while welding.
- Wear proper gloves and protective clothing to prevent your skin from being exposed
to hot metals, UV and IR rays.
- Do not overuse or overheat your welder. Allow proper cooling time between duty
cycles.
- Keep hands and fingers away from moving parts and stay away from the drive rolls.
- Do not point torch at any body part of yourself or anyone else.
- Always use this welder in the rated duty cycle to prevent excessive heat and failure.
1.4 Specific Areas of Danger, Caution or Warning
Electrical Shock
Electric arc welders can produce a shock that can cause injury or death. Touching
electrically live parts can cause fatal shocks and severe burns. While welding, all metal
components connected to the wire are electrically hot. Poor ground connections are a
hazard, so secure the ground lead before welding.
- Wear dry protective apparel: coat, shirt, gloves and insulated footwear.
- Insulate yourself from the work piece. Avoid contacting the work piece or ground.
- Do not attempt to repair or maintain the welder while the power is on.
- Inspect all cables and cords for any exposed wire and replace immediately if found.
- Use only recommended replacement cables and cords.
- Always attach ground clamp to the work piece or work table as close to the weld
area as possible.
- Do not touch the welding wire and the ground or grounded work piece at the same time.
- Do not use a welder to thaw frozen pipes.
Fumes and Gases
- Fumes emitted from the welding process displace clean air and can result in injury
or death.
- Do not breathe in fumes emitted by the welding process. Make sure your breathing
air is clean and safe.
