ESAB Ruffian ES 150G EDW Instruction Manual page 5

1 SAFETY
6. Protect other personnel from arc rays and hot sparks with a suitable non-flammable
partition or curtains.
7. Use goggles over safety glasses when chipping slag or grinding. Chipped slag may be hot
and can fly for long distances. Bystanders should also wear goggles over safety glasses.
FIRES AND EXPLOSIONS
The heat from flames and arcs can start fires. Hot slag or sparks can also
cause fires and explosions. Therefore:
1. Protect yourself and others from flying sparks and hot metal.
2. Move all combustible materials well away from the work area or cover the materials with a
protective non-flammable covering. Combustible materials include wood, cloth, sawdust,
liquid and gas fuels, solvents, paints, and coating paper, etc.
3. Hot sparks or hot metal can fall through cracks or crevices in floors or wall openings and
cause a hidden smoldering fire or fires on the floor below. Make certain that such openings
are protected from hot sparks and metal.
4. Do not weld, cut, or perform other hot work until the work piece has been completely
cleaned so that there are no substances on the work piece which might produce flammable
or toxic vapors. Do not perform hot work on closed containers, they may explode.
5. Have fire extinguishing equipment handy for instant use, such as a garden hose, water
pail, sand bucket, or portable fire extinguisher. Be sure you are trained in its use.
6. Do not use equipment beyond its ratings. For example, an overloaded welding cable can
overheat and create a fire hazard.
7. 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.
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 ground of
the input power.
2. Connect the workpiece to a good electrical earth 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 both the work piece and
from the ground.
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 for specific grounding recommendations. Do not
mistake the work lead for an earth cable.
