Considerations About Welding And The Effects Of Low Frequency Electric And Magnetic Fields
Welding current, as it flows through welding 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 welding or cutting.
WARNING
H.F. RADIATION can cause interference.
• High-frequency (H.F.) can interfere with radio navigation, safety services, computers, and communica -
tions equipment.
• Have only qualified persons familiar with electronic equipment install, test, and service H.F. producing
units.
• The user is responsible for having a qualified electrician promptly correct any interference problem
resulting from the installation.
• If notified by the FCC about interference, stop using the equipment at once.
• Have the installation regularly checked and maintained.
• 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.
About Implanted Medical Device
WARNING
MAGNETIC FIELDS can affect Implanted Medical Devices.
• Wearers of Pacemakers and other Implanted Medical Devices should keep away from servicing areas
until consulting their doctor and the device manufacturer.
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 operator as practical.
5. Connect work clamp to workpiece as close to the weld as possible.
