MOVING PARTS can cause injury.
D Keep away from moving parts such as fans.
D Have only qualified persons remove doors,
panels, covers, or guards for maintenance as
necessary.
D Keep hands, hair, loose clothing, and tools away from moving
parts.
D Reinstall doors, panels, covers, or guards when maintenance is
finished and before reconnecting input power.
MAGNETIC FIELDS can affect Implanted
Medical Devices.
D Wearers 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.
D Allow cooling period; follow rated duty cycle.
D Reduce current or reduce duty cycle before us-
ing induction heating equipment again.
D Do not block or filter airflow to unit.
H.F. RADIATION can cause interference.
D High-frequency (H.F.) can interfere with radio
navigation, safety services, computers, and
communications equipment.
D Have only qualified persons familiar with
electronic equipment install, test, and service
H.F. producing units.
D The user is responsible for having a qualified electrician prompt-
ly correct any interference problem resulting from the installa-
tion.
D If notified by the FCC about interference, stop using the
equipment at once.
D Have the installation regularly checked and maintained.
D Keep 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.
D Use Testing Booklet (Part No. 150 853) when
servicing this unit.
D Consult the Owner’s Manual for induction heat-
ing safety precautions.
D Use only genuine replacement parts from the
manufacturer.
8-3. 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. Wash 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.

Considerations About Induction Heating And The Effects Of Low Fre-
quency Electric And Magnetic Fields
Induction heating current, as it flows through induction heating cables,
will cause electromagnetic 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 using induction heating equipment.
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 induction heating power source and cables as far away
from operator as practical.
5. Connect work clamp to workpiece as close to the weld as
possible.
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.
