FUMES AND GASES
Welding may produce hazardous fumes and gas during the welding process. A well ventilated work area can
normally remove the fumes and gases, but sometimes the welding produces fumes and gases that are
hazardous to your health.
Stop welding if your eyes, nose or throat become irritated. This indicates the ventilation is not adequate to
remove the fumes. Do not resume welding until the ventilation is improved and the discomfort ceases.
1. Only work in a confined space if the area is well ventilated or while wearing an air-supplied respirator.
Always have a trained watchperson nearby.
2. Avoid positions that allow welding fumes to reach your face.
3. Ventilate the work area to remove welding fumes and gases. The fumes and gases should be drawn away
from the user. Welding fumes and gases can displace air and lower the oxygen level causing injury or
death. Be sure the breathing air is safe.
a. If ventilation in the work area is poor, use an approved air-supplied respirator. All the people in the
work area must also have air-supplied respirators.
4. Avoid welding in a work area that has vapours from cleaning, degreasing or any spraying operations. The
heat and light from welding can react with the vapour and form irritating or potentially toxic gases. Wait
for the vapours to disperse.
5. Consult the manufacturer's Material Safety Data Sheets (MSDS) for instructions and precautions about
metals, consumables, coatings, cleaners and degreasers.
a. Do not weld on coated metals such as galvanized, lead or cadmium plated steel, unless the coating is
removed from the weld area. The coatings and any metals containing these elements can give off
toxic fumes during the welding process.
b. Do not weld, cut or heat lead, zinc, cadmium, mercury, beryllium or similar metals without seeking
professional advice and inspection of the welding area’s ventilation. These metals produce extreme
toxic fumes, which can cause discomfort, illness and death.
c. Do not weld or cut near chlorinated solvents or in areas that chlorinates solvents can enter. The heat
or ultraviolet light of the arc can separate chlorinated hydrocarbons into a toxic gas (phosgene) that
can poison or suffocate the user or bystanders.
ELECTRICAL SAFETY
Touching live electrical parts can cause fatal shocks or severe burns. The input power circuit and machine
internal circuits are also live when the power is on. Incorrectly installed or improperly grounded equipment
is a hazard.
1. Do not come into contact with live electrical parts.
2. Wear dry, hole-free insulating gloves and body protection.
3. Additional safety precautions are required when any of the following electrically hazardous conditions are
present: in damp locations or while wearing wet clothing; on metal structures such as floors, gratings, or
scaffolds; when in cramped positions such as sitting, kneeling, or lying; or when there is a high risk of
unavoidable or accidental contact with the workpiece or ground. For these conditions, see ANSI Z49.1.
WARNING! Do not work alone.
4. Properly install and ground this equipment according to all national and local codes.
5. Always verify the supply ground – check and be sure that the input power cord ground wire is properly
connected to a properly grounded receptacle outlet.
6. When making input connections, attach the grounding conductor first and then double check
the connections.
