Instructions for Assembly and Operation Safety instructions
In the environment of resistance welding systems magnetic field strengths have to
be expected 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 for operating personnel!
When using manual welding guns, the limit values may be exceeded for the ex-
!
tremities. 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.
WARNING for persons with cardiac pacemakers!
Warning signs should be posted for protecting persons with cardiac pacemakers
!
because the function of these devices may be disturbed (impulse failure, total fail-
ure) and a negative influence on the pacemaker programming or even a total pro-
gram destruction may occur !!!
We recommend posting a warning of the type shown below at all entrances to fac-
tory halls containing resistance welding equipment:
DIN 40023
No entry for persons with cardiac
pacemakers!
Danger!
