Assemble the wire guide

The Euro torch connector is factory-fitted with a guide tube for welding torches with steel liner. Conver-
sion 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.
