1-2 SAFETY INSTRUCTIONS Manual 0-5401
ELECTRICAL 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 work piece to a good electrical ground.
3. Connect the work cable to the work piece. 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.
ELECTRIC AND MAGNETIC FIELDS — May be dangerous. Electric current flowing through any
conductor causes localized Electric and Magnetic Fields (EMF ). Welding and cutting current creates
EMF around welding cables and welding machines. Therefore:
1. Welders having pacemakers should consult their physician 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 minimize 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 work piece as close as possible to the area being welded.
E. Keep welding power source and cables as far away from your body as possible.
FUMES AND GASES -- Fumes and gases, can cause discomfort or harm, particularly in confined
spaces. Do not breathe fumes and gases. Shielding gases can cause asphyxiation.
Therefore:
1. Always provide adequate ventilation in the work area by natural or mechanical means. Do not weld,
cut, or gouge on materials such as galvanized steel, stainless steel, copper, zinc, lead, beryllium, or
cadmium unless positive mechanical ventilation is provided. Do not breathe fumes from these materials.
2. Do not operate near degreasing and spraying operations. The heat or arc rays can react with chlorinated
hydrocarbon vapors to form phosgene, a highly toxic gas, and other irritant gases.
3. If you develop momentary eye, nose, or throat irritation while operating, this is an indication that
ventilation is not adequate. Stop work and take necessary steps to improve ventilation in the work
area. Do not continue to operate if physical discomfort persists.
4. Refer to ANSI/ASC Standard Z49.1 (see listing below) for specific ventilation recommendations.
5. WARNING: This product contains chemicals, including lead, known to the State of California to cause
birth defects and other reproductive harm. Wash hands after handling.
