This manual is designed for technicians and engineers with special welding
training and skills. They must have a sound knowledge of the hardware com-
ponents of the weld control system, the PST 6000 thyristor power units and
the welding transformers.
Interventions in the hardware and software of our products, unless de-
scribed otherwise in this manual, are reserved to specialized Bosch person-
nel.
Tampering with the hardware or software, ignoring warning signs attached to
the components, or non-compliance with the warning notes given in this
manual can result in serious bodily injury or property damage.
Only skilled persons as defined in IEV 826-09-01 who are familiar with the
contents of this manual may install and service the products described.
Such personnel are
D those who, being well trained and experienced in their field and familiar
with the relevant standards, are able to analyze the work to be carried out
and recognize any hazards.
D those who have acquired the same amount of expert knowledge through
years of experience that would normally be acquired through formal tech-
nical training.
DANGER!
An exception are persons with cardiac pacemakers!
The strong magnetic fields occurring in resistance welding may af-
fect the proper functioning of pacemakers. This may be fatal or cause
serious personal injury!
Therefore, persons with pacemakers must stay clear of resistance
welding systems.
We recommend that warning sings as per DIN 40023 are posted at ev-
ery entrance to manufacturing shops housing resistance-welding
equipment.
