Care, maintenance and disposal

General

Regular preventive maintenance of the welding torch is essential if trouble-free operation
is to be ensured. The welding torch is subjected to high temperatures and heavy soiling.
The welding torch therefore requires more frequent maintenance than other components
in the welding system.
