EMF Information

Electric current flowing through any conductor causes localized electric
and magnetic fields (EMF). Welding current creates an EMF field
around the welding circuit and welding equipment. EMF fields may inter-
fere with some medical implants, e.g. pacemakers. Protective meas-
ures for persons wearing medical implants have to be taken. For ex-
ample, restrict access for passers−by or conduct individual risk assess-
ment for welders. All welders should use the following procedures in or-
der to minimize exposure to EMF fields from the welding circuit:

1.

Keep cables close together by twisting or taping them, or using a
cable cover.

2.

Do not place your body between welding cables. Arrange cables
to one side and away from the operator.

3.

Do not coil or drape cables around your body.

4.

Keep head and trunk as far away from the equipment in the
welding circuit as possible.

5.

Connect work clamp to workpiece as close to the weld as
possible.

6.

Do not work next to, sit or lean on the welding power source.

7.

Do not weld whilst carrying the welding power source or wire
feeder.

About Implanted Medical Devices:
Implanted Medical 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.
