Service, maintenance and disposal
General Regular and preventive maintenance of the welding torch are important factors in achie-
ving problem-free operation. The welding torch is subjected to high temperatures and
high levels of soiling. This is why the welding torch needs more frequent maintenance
than other components of the welding system.
NOTE!
Avoid scoring and scratches when
removing welding spatter,
because welding spatter that develops in
continued operation could permanently
solidify therein.
Do not bend the torch body under any cir-
cumstances!
