Welding torch and workpiece line connection
Depending on the wire electrode diameter or type, either a steel liner or 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 liner to weld or braze soft wire electrodes, high-alloy wire electrodes or aluminium materials.
On delivery, the Euro torch connector is fitted with a capillary tube for welding torches with a
steel liner. Conversion is necessary if a welding torch with a liner is used!
• Operate welding torches with a liner > with a guide tube.
• Operate welding torches with a steel liner > with a capillary tube.
Preparation work 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 there.
• Slide plastic core support tube off the central connector.
• Carefully insert the central plug for the welding torch, with the still oversized plastic core, into the
central connector and screw together with crown nut.
• Use a suitable tool to cut off the plastic core shortly 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 work for connecting welding torches with a spiral guide:
• Check that the capillary tube is correctly positioned in relation to the central connector!
