For installation of a PA/ Bronze liner used for Alu or stainless steel wires, please follow the instructions included
with the liner.
Complete the following steps to install an insulated liner for steel wire:
1. Remove the torch neck from the torch, see Section 3.3.3. Remove gas nozzle, contact tip and tip
holder.
2. Loosen and unscrew inlet guide (102).
3. Pull the old wire guide backwards out of the torch neck. To do this, press the wire guide into the neck
from the front if necessary.
4. Blow out the torch neck with compressed air.
5. Reassemble tip holder, contact tip and gas nozzle.
6. Select new wire guide (J) to suit the welding wire. Monitor the front end for a free inner hole and
protruding burrs; rework if necessary.
7. Insert the new wire guide (J) into the torch neck from the back.
Note: The bare end of the liner must point forwards towards the contact tip.
8. Hold the wire guide in the torch neck whilst applying light pressure to ensure that it pushes forward
against the contact tip. Then cut the wire guide flush with the end of the torch neck.
9. Monitor the end of the wire guide for a free inner hole and protruding burrs. It has to be able to be
inserted into the liner nipple later on. Remove the wire guide from the neck again and rework if
necessary.
10. When using the yellow steel liner (111 A), the insulation must be removed on a length of 6 mm in order
to insert the liner into the nipple (see drawing).
11. The inlet guide (102) included in the equipment set must always be used. Screw inlet guide on to the
torch neck and lightly tighten.
Note: The wire guide must be inserted into the large borehole of the inlet guide in order to minimize the
loss of gas.
12. Check the O-rings on the flange of the torch neck for damage or loss; replace if necessary.
13. Put on the torch neck and tighten the locking nut by hand. Do not use any tools!
