EMF Information
Welding or cutting current, as it flows through the cables will cause electromagnetic fields. There has been and still
is some concern about such fields. However, after examination, the 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 a magnetic field 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.
To reduce magnetic fields in the workplace, use the following procedures:
1. Keep cables close together by twisting or taping them when possible.
2. Arrange cables to one side and away from the operator.
3. Do not coil or drape cables around your body.
4. Keep plasma cutting machine and cables as far away from operator as practical.
5. Connect GROUND CLAMP (4) to workpiece as close to the cut or weld as possible.
ABOUT PACEMAKERS & HEARING AIDS: Pacemaker and hearing aid wearers consult your doctor first.
If cleared by your doctor, then following the above procedures is recommended.
Plasma Arc Cutting Hazards
CUTTING CAN CAUSE FIRE OR EXPLOSION. Hot metal and sparks blow out from the cutting arc.
The flying sparks and hot metal, hot workpiece, and hot equipment can cause fires and burns. Check and be sure
the area is safe before doing any cutting.
• Do not cut in an area until it is checked and cleared of combustible and/or flammable materials. Be aware
that sparks and slag can fly 35 feet and can pass through small cracks and openings. If workpiece and
combustibles cannot be separated by a minimum of 35 feet, protect against ignition with suitable, snug-fitting,
fire resistant, covers or shields.
• Connect the GROUND CABLE (4) to the workpiece as close as possible to the welding or cutting area. Do not
connect GROUND CABLES to building framing or other locations away from the welding or cutting area. This
increases the possibility of welding/cutting current passing through alternate circuits, creating fire hazards and
other safety hazards.
