GENERAL INFORMATION 1-4 Manual 0-5197AC
CYLINDERS CAN EXPLODE
Shielding gas cylinders contain gas under high pressure. If dam-
aged, a cylinder can explode. Since gas cylinders are normally part
of the welding process, be sure to treat them carefully.
• Protect compressed gas cylinders from excessive heat, mechani-
cal shocks, and arcs.
• Install and secure cylinders in an upright position by chain-
ing them to a stationary support or equipment cylinder rack to
prevent falling or tipping.
• Keep cylinders away from any welding or other electrical circuits.
• Never allow a welding electrode to touch any cylinder.
• Use only correct shielding gas cylinders, regulators, hoses, and
fi ttings designed for the specifi c application; maintain them and
associated parts in good condition.
• Turn face away from valve outlet when opening cylinder valve.
• Keep protective cap in place over valve except when cylinder is in
use or connected for use.
• Read and follow instructions on compressed gas cylinders,
associated equipment, and CGA publication P-1 listed in Safety
Standards.

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 Section
of the U.S. Congress, Offi ce of Technology Assessment, Biological
Effects of Power Frequency Electric & Magnetic Fields - Background
Paper, OTA-BP-E-63 (Washington, DC: U.S. Government Printing
Offi ce, May 1989): “...there is now a very large volume of scientifi c
fi ndings based on experiments at the cellular level and from studies
with animals and people which clearly establish that low frequency
magnetic fi elds and interact with, and produce changes in, biological
systems. While most of this work is of very high quality, the results
are complex. Current scientifi c 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 defi nite conclusions about
questions of possible risk or to offer clear science-based advice on
strategies to minimize or avoid potential risks.” To reduce magnetic
fi elds 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.
