Welding torch and workpiece line connection

Fault with the wire guide!
On delivery, the central connector is fitted with a capillary tube for welding torches with
spiral guides. Conversion is necessary if a welding torch with a plastic core is used!
Welding torch with plastic core:
•
use with guide tube!
Welding torch with spiral guide:
•
use with capillary tube!
Depending on the wire electrode diameter or type, either a steel liner or plastic liner with the
correct inner diameter must be inserted in the torch!
Recommendation:
•
Use a steel liner when welding hard, unalloyed wire electrodes (steel).
•
Use a chrome nickel liner when welding hard, high-alloy wire electrodes (CrNi).
•
Use a plastic core to weld or braze soft wire electrodes, high-alloy wire electrodes or aluminium
materials.
Preparation for connecting welding torches with a plastic core:
•
Push forward the capillary tube on the wire feed side in the direction of the central connector and
remove it there.
•
Slide plastic core guide tube off the central connector.
•
Carefully insert the central plug for the welding torch, with the still oversized plastic liner, into the
central connector and screw together with crown nut.
•
Use a suitable tool to cut off the plastic liner just before the wire feed roller, making sure not to pinch it.
•
Unfasten and remove the central plug on the welding torch.
•
Cleanly remove the burr from the separated end of the plastic core!
Preparation for connecting welding torches with a spiral guide:
•
Check that the capillary tube is correctly positioned in relation to the central connector!
