5.1 TORCH PREPARATION
Depending on the welding wire diameter and the wire electrode type it has to be used a spiral liner
or a plastic/Teon/graphite liner with an internal diameter adequate to the welding torch and the
used wire.
Suggestion:
• For the welding of hard wire electrodes (steel) use a spiral sheath
• For the welding or the brazing of soft wire electrodes use a plastic/Teon/graphite liner
In case of wire feeder sheath replacement carefully follow these instructions:
A B C
Torch side: remove the gas nozzle
(A)
Unscrew the wire guide tip(B) Connector side (C)
D E F
Unscrew the termination nut (D,E) Complete the sheath extraction (F) Grab the sheath end by a nipper and
start to extract it (F)
G B A
Insert the new sheath and push it
deep inside (G)
Screw in again the wire guide tip on
the torch
Complete the replacement of the
