1-3. 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 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, 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.
About Implanted Medical Devices:
ImplantedMedical Device wearers should consult their doctor and the
device manufacturer before performing or going near arc welding, spot
welding, gouging, plasma arc cutting, or induction heating operations.
If cleared by your doctor, then following the above procedures is recom-
mended.

Trouble Remedy
Wire does not feed; wire is not ener-

Check gun trigger plug connection at welding power source/wire feeder.
Check, and if necessary, replace gun trigger switch (see Section 4-2).
Check contact tip. Check for kinks in gun cable. Blow out liner and gun casing (see Section 4-1).
Weld porosity. Remove weld spatter buildup in nozzle.
Check O-rings on gun connector and replace if damaged.
Make sure inner head tube is tight in cable connector.
Check gun connector to be sure it is fully inserted into drive assembly.
Check shielding gas flow/supply.
Wire feeding stops or does not feed
properly during welding. Straighten gun cable and/or replace damaged parts (see Section 4-1).
Adjust drive roll pressure (see wire feeder manual).
Change to proper drive roll groove (see wire feeder manual).
Readjust hub tension (see wire feeder manual).
Clean or replace liner if dirty or plugged (see Section 4-1).
Replace drive roll or pressure bearing if worn or slipping (see wire feeder manual).
