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 mainten-
ance than other components in the welding system.
CAUTION!
Risk of damage from improper hand-
ling 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 spat-
ter may become firmly lodged.
▶
Do not bend the torch body under
any circumstances!
