V4.1
7. Do not handle hot metal or electrode stubs with bare hands. Handling may result in a burn injury.
8. Do not use the welding unit if personal movement is confined or if there is a danger of falling.
9. Keep all panels and covers securely in place when operating the welding unit.
10. Insulate the work clamp when not connected to a workpiece to prevent contact with any metal object.
11. Do not operate the welding unit if the output cable or torch is wet. Do not immerse them in water. These
components and the welding unit must be completely dry before attempting to use them.
12. Do not point the torch at any body part of yourself or at anyone else.
13. Do not use a welding unit to thaw frozen pipes.
14. Insulate yourself from the work and the ground using dry insulation. Make certain that the insulation is large enough
to cover your full area of physical contact with the work and the ground.
15. Never dip the electrode in water for cooling.
FIRE AND EXPLOSION PRECAUTIONS
Arc welding can produce sparks, hot slag or spatter, molten metal drops and hot metal parts that can start fires.
1. Clear the floor and walls of an area of all combustible and/or flammable materials. Hot debris ejected during welding
can land at a considerable distance way. Solid floors of concrete or masonry is the preferred working surface.
a. Cover any combustible material with fire resistant covers or shields, if it cannot be removed.
2. Check that there are no openings or cracks that hot debris can enter.
3. Check both sides of a panel or wall for combustible material. Remove the combustible material before welding.
4. Have a fire extinguisher available for immediate use. A dry chemical fire extinguisher with
Types A, B and C is suggested.
a. Welding a combustible metal like zinc, magnesium or titanium requires a Type D fire extinguisher.
b. Do not use liquid based fire extinguishing methods near the electric arc welding unit, as it may cause a
shock hazard.
5. Do not perform any welding work on containers that held flammable or toxic substance until they are cleaned by a
person trained in removing toxic and flammable substances and vapours.
6. Open a container before performing any welding work on it. The heat generated by the welding process will cause
the air and gases to expand. The internal pressure may cause a sealed or closed container to rupture, possibly
causing an injury or death.
FUMES AND GASES PRECAUTIONS
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.
