5.3.1

Assemble the wire guide

The Euro torch connector is factory-fitted with a guide tube for welding torches with steel liner. Conversi-
on is necessary if a welding torch with a steel liner is used!
• Operate welding torches with a liner > with a guide tube!
• Operate welding torches with a steel liner > with a capillary tube!
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 plastic or teflon liner when welding or brazing soft wire electrodes, high-alloy wire electrodes or
aluminium materials.
Preparation for connecting welding torches with a spiral guide:
• Check that the capillary tube is correctly positioned in relation to the central connector!
Preparation for connecting welding torches with a liner:
• Push forward the capillary tube on the wire feed side in the direction of the Euro torch connector and
remove it there.
• Insert the liner guide tube from the Euro torch connector side.
• Carefully insert the welding torch connector with as yet too long a liner into the Euro torch connector
and secure with a crown nut.
• Cut off the liner with a liner cutter > see 9 chapter just before the wire feed roller.
• Loosen the welding torch connector and remove.
• Carefully chamfer the cut off end of the liner with a liner sharpener > see 9 chapter and sharpen.
