24 Maintenance and repair
Please observe the current safety
and accident prevention regulations
during all maintenance and repair
work.
The machine requires a minimum of care and
maintenance. Only a few items need to be
checked to ensure trouble-free long-term opera-
tion.
24.1 Check regularly
‰ Check the following points for damage before
starting up the welding machine:
– Mains plug and cable
– Welding torch and connections
– Ground cable and connection
‰ Blow the welding machine out once or twice a
year.
 To do this, switch the device and disconnect
the mains plug.
 Using dry compressed air, blow the welding
machine out from the front through the venti-
lation slots. Leave the housing closed.
Never blow the compressed air through
the ventilation holes on the rear side of
the machine. The fan is located there
and the compressed air would make
it turn so quickly that bearing damage
may result.
