SHOCK -- Contact with live electrical parts and ground 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.
1. Be sure the power
source frame (chassis) is connected to the ground system of the input power.
2. Connect the workpiece
to a good electrical ground. 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 work and from ground.
7. Do not stand directly
on metal or the earth 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 ground cable.
