EMF INFORMATION
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 seventeen 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 operator as possible.
5. Connect work clamp to workpiece as close to
the weld as possible.
About Pacemakers:
Pacemaker wearers consult your doctor before welding
or going near welding operations. If cleared by your
doctor, then following the above procedures is
recommended.
