8 Maintenance
8.1 Stud welder
The stud welders are constructed in such a way that only a minimum of
maintenance is required. The interior of the stud welders should, however, be
cleaned by a specialist at regular intervals depending on the environmental
conditions at the location of use. Any defects of the system's control part can
easily be eliminated by replacing the printed circuit and/or the clearly arranged
fuses.
Ꮨ
MORTAL DANGER
Before replacing any components, disconnect the mains cable from the
mains supply. Electric and electronic components may only be replaced by
a specialist. Contact the SOYER
® service department, if necessary.

DANGER TO HEALTH
Before starting repair works, disconnect the mains cable from the power
supply and the compressed-air supply from the stud welder connections.
• Unscrew recessed-head screws at both side parts. Remove upper part of
the housing by lifting it vertically from the unit (please pay attention to the
earth connection).
• Blow through the interior of the stud welder using clean, dry and filtered
compressed air with a pressure of about 2 bar. If no compressed air is
available, a vacuum cleaner may be used instead. Ensure, however, that no
components are damaged by the nozzle.
• Replace the cover and secure it using the recessed-head screws (please
pay attention to the earth connection).
8.2 Replacement of components
Defective components may only be replaced by trained SOYER servicemen.
Perfect function of your stud welder can only be guaranteed if original SOYER
spare parts are used.
Ꮨ
MORTAL DANGER
Ensure that the mains plug has been disconnected and the capacitors are
discharged before opening the housing to replace components.
