H.F. RADIATION can cause

interference.

� High-frequency (H.F.) can interfere with radio navi-

gation, safety services, computers, and communi-

cations equipment.

� Have only qualified persons familiar with electronic equipment per-

form this installation.

� The user is responsible for having a qualified electrician promptly

correct any interference problem resulting from the installation.

� If notified by the FCC about interference, stop using the equipment

at once.

� Have the installation regularly checked and maintained.

� Keep high-frequency source doors and panels tightly shut, keep

spark gaps at correct setting, and use grounding and shielding to

minimize the possibility of interference.

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.

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.
