SeCTION 1
1. Be sure the power source frame (chassis) is con-
nected 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 recommenda-
tions. Do not mistake the work lead for a ground
cable.

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.
B. Never coil the torch or work cable around your
C. Do not place your body between the torch and
D. Connect the work cable to the workpiece as close
E. Keep welding power source and cables as far
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, stain-
less 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 opera-
tions. 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 ir-
ritation 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 discom-
fort persists.
4. Refer to ANSI/ASC Standard Z49.1 (see listing below)
for specific ventilation recommendations.
