Welding torch and workpiece line connection

Fault with the wire guide!
On delivery, the central connector (Euro) 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 and wire electrode type, either a spiral guide or a
plastic core with the appropriate interior diameter must be inserted into the welding torch!
Recommendation:
• Use a spiral guide for welding hard wire electrodes (steel).
• Use a plastic liner for welding or brazing soft wire electrodes.
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!
