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 to match the gas nozzle and torch
geometry, moves into the gas nozzle's interior by means
of a stroke movement and removes adhered welding
spatter. At the same time, the gas nozzle interior may be
blasted with compressed air through the cable assembly
(optional). Hereby, the cleaning process is optimized in
connection with an optional anti-spatter application.
