WARNING
This product, when used for welding or cutting,
produces fumes or gases which contain chemicals
know to the State of California to cause birth defects
and, in some cases, cancer. (California Health &
Safety code Sec. 25249.5 et seq.)
NOTE
Considerations About Welding And The Effects of
Low Frequency Electric and Magnetic Fields
The following is a quotation from the General Conclusions Sec-
tion of the U.S. Congress, Office of Technology Assessment,
Biological Effects of Power Frequency Electric & Magnetic Fields
- Background Paper, OTA-BP-E-63 (Washington, DC: U.S. Gov-
ernment Printing Office, May 1989): “...there is now a very large
volume of scientific findings based on experiments at the cellular
level and from studies with animals and people which clearly es-
tablish that low frequency magnetic fields and interact with, and
produce changes in, biological systems. While most of this work
is of very high quality, the results are complex. Current scientific
understanding does not yet allow us to interpret the evidence
in a single coherent framework. Even more frustrating, it does
not yet allow us to draw definite conclusions about questions of
possible risk or to offer clear science-based advice on strategies
to minimize or avoid potential risks.”
To reduce magnetic fields in the workplace, use the following
procedures.
1. Keep cables close together by twisting or taping them.
2. Arrange cables to one side and away from the operator.
3. Do not coil or drape cable around the body.
4. Keep welding power source and cables as far away from body
as practical.
ABOUT PACEMAKERS:
The above procedures are among those also
normally recommended for pacemaker wearers.
Consult your doctor for complete information.
WARNING
FLYING SPARKS AND HOT METAL can cause
injury.
Chipping and grinding cause flying metal. As welds
cool, they can throw off slag.
1. Wear approved face shield or safety goggles. Side shields
recommended.
2. Wear proper body protection to protect skin.
WARNING
CYLINDERS can explode if damaged.
Shielding gas cylinders contain gas under high pres-
sure. If damaged, a cylinder can explode. Since gas
cylinders are normally part of the welding process,
be sure to treat them carefully.
1. Protect compressed gas cylinders from excessive heat,
mechanical shocks, and arcs.
2. Install and secure cylinders in an upright position by chaining
them to a stationary support or equipment cylinder rack to
prevent falling or tipping.
3. Keep cylinders away from any welding or other electrical
circuits.
4. Never allow a welding electrode to touch any cylinder.
5. Use only correct shielding gas cylinders, regulators, hoses,
and fittings designed for the specific application; maintain
them and associated parts in good condition.
6. Turn face away from valve outlet when opening cylinder
valve.
7. Keep protective cap in place over valve except when cylinder
is in use or connected for use.
8. Read and follow instructions on compressed gas cylinders,
associated equipment, and CGA publication P-1 listed in
Safety Standards.
WARNING
MOVING PARTS can cause injury.
Moving parts, such as fans, rotors, and belts can cut fingers and
hands and catch loose clothing.
1. Keep all doors, panels, covers, and guards closed and securely
in place.
2. Stop engine before installing or connecting unit.
3. Have only qualified people remove guards or covers for
maintenance and troubleshooting as necessary.
4. To prevent accidental starting during servicing, disconnect
negative (-) battery cable from battery.
5. Keep hands, hair, loose clothing, and tools away from moving
parts.
6. Reinstall panels or guards and close doors when servicing
is finished and before starting engine.
