MOVING PARTS can cause injury.
D
Keep away from moving parts.
D
Keep away from pinch points such as drive
rolls.
MAGNETIC FIELDS can affect pacemak-
ers.
D
Pacemaker wearers keep away from servicing
areas until consulting your doctor.
OVERUSE can cause OVER-
HEATING.
D
Allow cooling period; follow rated duty cycle.
D
Reduce current or reduce duty cycle before
starting to weld 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.

Considerations About Welding And The Effects Of Low Frequency
Electric And Magnetic 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.
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 Pacemakers:
Pacemaker wearers consult your doctor first. If cleared by your doctor,
then following the above procedures is recommended.
