1 SAFETY PRECAUTIONS
5. Do not use equipment beyond its ratings. For example, overloaded welding cable can
overheat and create a fire hazard.
6. After completing work, inspect the work area to make sure there are no hot sparks or hot
metal that could cause a fire later. Use fire watchers when necessary.
7. For additional information, refer to NFPA Standard 51B, "Fire Prevention in Use of
Cutting and Welding Processes," available from the National Fire Protection Association,
Batterymarch Park, Quincy, MA 02269.
ELECTRICAL SHOCK
Contact between live electrical parts and earth can cause severe injury
or death. DO NOT use AC welding current in damp areas, if movement
is confined, or if there is danger of falling. Therefore:
1. Be sure the power source frame (chassis) is connected to the earth system of the input
power.
2. Connect the workpiece to a good electrical earth.
3. Connect the work cable to the workpiece. A poor or missing connection can expose you
or others to a fatal shock.
4. Use well-maintained equipment. Replace worn or damaged cables.
5. Keep everything dry, including clothing, work area, cables, torch/electrode holder and
power source.
6. Make sure that all parts of your body are insulated from the workpiece and from earth.
7. Do not stand directly on metal or the ground while working in tight quarters or a damp
area; stand on dry boards or an insulating platform and wear rubber-soled shoes.
8. Put on dry, hole-free gloves before turning on the power.
9. Turn off the power, before removing your gloves.
10. Refer to ANSI/ASC Standard Z49.1 (listed on next page) for specific grounding
recommendations. Do not mistake the work lead for a earth cable.
ELECTRIC AND MAGNETIC FIELDS
May be dangerous. Electric current flowing through any conductor
causes localised Electric and Magnetic Fields (EMF). Welding and
cutting current creates EMF around welding cables and welding
machines. Therefore:
1. Welders with pacemakers fitted should consult their doctor before welding. EMF may
interfere with some pacemakers.
2. Exposure to EMF may have other health effects which are unknown.
3. Welders should use the following procedures to minimise exposure to EMF:
a) Route the electrode and work cables together. Secure them with tape when possible.
b) Never coil the torch or work cable around your body.
c) Do not place your body between the torch and work cables. Route cables on the
same side of your body.
d) Connect the work cable to the workpiece as close as possible to the area being
welded.
e) Keep the welding power source and cables as far away from your body as possible.
