ARC WELDING can cause
interference.
lElectromagnetic energy can interfere with sensitive
electronic equipment such as microprocessors,
computers, and computer-driven equipment such
as robots.
lBe sure all equipment in the welding area is electromagnetically
compatible.
lTo reduce possible interference, keep weld cables as short as
possible, close together, and down low, such as on the floor.
lLocate welding operation 100 meters from any sensitive electronic
equipment.
lBe sure this welding machine is installed and grounded according
to this manual.
lIf interference still occurs, the user must take extra measures such
as moving the welding machine, using shielded cables, using line
filters, or shielding the work area.

1-8. EMF Information
Electric current flowing through any conductor causes localized elec-
tric and magnetic fields (EMF). The current from arc welding (and al-
lied processes including spot welding, gouging, plasma arc cutting,
and induction heating operations) creates an EMF field around the
welding circuit. EMF fields can interfere with some medical implants,
e.g. pacemakers. Protective measures for persons wearing medical
implants have to be taken. For example, restrict access for passers
−by or conduct individual risk assessment for welders. All welders
should use the following procedures in order 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 weld-
ing 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 opera-
tions. If cleared by your doctor, then following the above procedures
is recommended.
