If necessary, clean contact surfaces with dry reduced compressed air. The pipe bends must be tightened to the specified torque. If a contact point is damaged, both the pipe bend and the hosepack must be replaced.

Care, maintenance and disposal General Regular preventive maintenance of the welding torch is essential if troublefree operation is to be ensured. The welding torch is subjected to high temperatures and heavy soiling. For this reason, the torch needs more frequent maintenance than other components of the welding system.
Troubleshooting Troubleshooting No welding current Mains switch ON, indicators on the power source are lit up, shielding gas flows Cause: Faulty earth (ground) connection Remedy: Check the earth (ground) connection and clamp for correct polarity Cause: There is a break in the current cable in the welding torch Remedy: Change the torch No protective gas shield...

The welding torch becomes very hot Cause: The swivel nut on the central connector is loose Remedy: Tighten the swivel nut Cause: The torch has been operated beyond its maximum amperage rating. Remedy: Lower the welding power or use a higher-capacity torch Cause: The design dimensions of the torch are not sufficient for this task Remedy:...
