SAFETY
Ⅰ
Always be sure the work cable makes a good electrical connection with the metal being welded. The
connection should be as close as possible to the area being welded.
Maintain the electrode holder, work clamp, welding cable and welding machine in good, safe
operating condition. Replace damaged insulation.
The electrode should never be cooled down by dipping it in water.
When two welding machines are close together, refrain from touching live parts simultaneously since
the combined voltage can increase shock level.
When working above floor level, a safety harness should be worn to obviate the danger of falling in
case of an electric shock.
FUMES AND GASES
During the welding process fumes and gases can be produced which may be detrimental to health.
Inhalation of fumes should be avoided by introducing adequate relief systems. When using welding
electrodes for stainless and hard-facing steel, lead or cadmium plated steel, galvanized steel or any other
coated metals which produce toxic fumes, special ventilation and exhaust systems must be introduced to
ensure exposure is kept below threshold limit values.
Welding in or near locations where chlorinated hydrocarbon vapors are produced such as degreasing,
cleaning and spraying operations should be avoided since phosgene, a highly-toxic gas as well as other
irritants can be reaction products.
Shielding gases can displace air causing breathing impairment. Therefore, adequate ventilation is of
prime importance especially when working in confined spaces.
Read and understand the manufacturer’s instructions for this equipment and the consumables to be
used, including the material safety data sheet and follow your employer’s safety practices.
ARC RAYS CAN BURN.
Use a shield with a proper filter and cover plates to protect eyes from sparks and rays.
For skin protection wear suitable clothing manufactured from flame-resistance material.
Ensure that nearby personnel are screened from arc effects by using non-flammable material and
safety warnings.
