1-6. EMF Information
Considerations About Welding Or Cutting And The Effects Of Low
Frequency Electric And Magnetic Fields
Welding or cutting current, as it flows through the welding or cutting
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.
To reduce magnetic fields in the workplace, use the following proce-
dures:
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 cutting power source and cables as far away from operator
as practical.
5. Connect work clamp to workpiece as close to the cut as possible.
About Pacemakers:
Pacemaker wearers consult your doctor before welding/cutting or going
near welding/cutting operations. If cleared by your doctor, then following
the above procedures is recommended.
