Warning of magnetic fields
!
VIII
In the environment of resistance welding systems magnetic field strengths have to be ex-
pected which usually are below the limits specified in VDE 0848 Part 4; in cases of doubt,
the field strength must be measured.
Dangers, if any, may arise from alternating magnetic fields (critical frequency: 1.6 Hz).
WARNING!
When using manual welding guns, the limit values may be exceeded for the extremities.
In this case, additional work protection measures must be taken.
So far, no problems have been reported. Nevertheless, the possible influences are lower
with medium-frequency welding than with AC welding.
NOTE
The strong magnetic fields arising in connection with resistance welding may cause last-
ing damages to wrist watches, pocket watches, or cards with magnetic stripes (e.g. EC
cards).
Therefore, you should not carry any such items on you when working in the direct vicinity
of the welding equipment.
