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.
CAUTION!
Risk of damage from improper handling
of the welding torch.
This can result in serious damage.
▶
Do not strike the welding torch on
hard objects.
▶
Avoid scoring and scratches in the
contact tip in which welding spatter
may become firmly lodged.
▶
Do not bend the torch body under any
circumstances!
