BRS-LCi VW
5 Functional Description
For cleaning, the torch is clamped with the cylindrical part of the gas nozzle in the clamping device. The
milling cutter which is configured for the gas nozzle and torch geometry moves into the gas nozzle interior
by means of compressed air and removes adhering welding spatters. The cleaning process is optimized by
an optional air-blast function through the cable assembly. Afterwards, the cleaned gas nozzle interior is
sprayed by the milling cutter with a dosed quantity of anti-spatter fluid against adhesion of spatter. An
additional valve is used to blow off any adherent dirt of the milling cutter.
