FALLING UNIT can cause injury.
DUse lifting eye to lift unit only, NOT running
gear, gas cylinders, or any other accessories.
DUse equipment of adequate capacity to lift and
support unit.
DIf using lift forks to move unit, be sure forks are
long enough to extend beyond opposite side of
unit.
MOVING PARTS can cause injury.
DKeep away from moving parts such as fans.
DKeep away from pinch points such as drive
rolls.
DHave only qualified persons remove doors,
panels, covers, or guards for maintenance as
necessary.
DKeep hands, hair, loose clothing, and tools
away from moving parts.
DReinstall doors, panels, covers, or guards
when maintenance is finished and before re-
connecting input power.
MAGNETIC FIELDS can affect Implanted
Medical Devices.
DWearers of Pacemakers and other Implanted
Medical Devices should keep away from serv-
icing areas until consulting their doctor and the
device manufacturer.
OVERUSE can cause OVERHEATING.
DAllow cooling period; follow rated duty cycle.
DReduce current or reduce duty cycle before
starting to weld again.
DDo not block or filter airflow to unit.
H.F. RADIATION can cause interference.
DHigh-frequency (H.F.) can interfere with radio
navigation, safety services, computers, and
communications equipment.
DHave only qualified persons familiar with
electronic equipment install, test, and service
H.F. producing units.
DThe user is responsible for having a qualified electrician prompt-
ly correct any interference problem resulting from the installa-
tion.
DIf notified by the FCC about interference, stop using the
equipment at once.
DHave the installation regularly checked and maintained.
DKeep high-frequency source doors and panels tightly shut, keep
spark gaps at correct setting, and use grounding and shielding to
minimize the possibility of interference.
READ INSTRUCTIONS.
DUse Testing Booklet (Part No. 150 853) when
servicing this unit.
DConsult the Owner’s Manual for welding safety
precautions.
DUse only genuine replacement parts from the
manufacturer.
6-3. California Proposition 65 Warnings
Welding or cutting equipment produces fumes or gases
which contain chemicals known to the State of California to
cause birth defects and, in some cases, cancer. (California
Health & Safety Code Section 25249.5 et seq.)
Battery posts, terminals and related accessories contain lead
and lead compounds, chemicals known to the State of
California to cause cancer and birth defects or other
reproductive harm. W ash hands after handling.
For Gasoline Engines:
Engine exhaust contains chemicals known to the State of
California to cause cancer, birth defects, or other reproduc-
tive harm.
For Diesel Engines:
Diesel engine exhaust and some of its constituents are
known to the State of California to cause cancer, birth
defects, and other reproductive harm.
6-4. EMF Information
Considerations About Welding And The Effects Of Low Frequency
Electric A n d M a g netic Fields
Welding current, as it flows through welding cables, will cause electro-
magnetic fields. There has been and still is some concern about such
fields. However, after examining more than 500 studies spanning 17
years of research, a special blue ribbon committee of the National
Research Council concluded that: “The body of evidence, in the
committee’s judgment, has not demonstrated that exposure to power-
frequency electric and magnetic fields is a human-health hazard.”
However, studies are still going forth and evidence continues to be
examined. Until the final conclusions of the research are reached, you
may wish to minimize your exposure to electromagnetic fields when
welding or cutting.
To reduce magnetic fields in the workplace, use the following
procedures:
1. Keep cables close together by twisting or taping them, or using a
cable cover.
2. Arrange cables to one side and away from the operator .
3. Do not coil or drape cables around your body.
4. Keep welding power source and cables as far away from opera-
tor as practical.
5. Connect work clamp to workpiece as close to the weld as possi-
ble.
About Implanted Medical Devices:
Implanted Medical Device wearers should consult their doctor and the
device manufacturer before performing or going near arc welding, spot
welding, gouging, plasma arc cutting, or induction heating operations.
If cleared by your doctor, then following the above procedures is recom-
mended.
