4.3 Wire run-in
1. Open cover (4) towards cable assembly, loosen tension spring holder (14) from locking device
and flip up to open.
2. Open pressure roll holder (20) and fold to the side.
3. Check that the drive roll has been correctly installed.
4. Manually straighten the first 10 cm of the welding wire to be inserted and work the tip and/or cut edge of
the wire in such a way that it is free of burrs and as “round” as possible. This can be done with a file or
with abrasive paper.
5. Now, with the cable assembly straightened out, manually insert the welding wire about 20 cm. To do
this, disengage the pressure roll of main drive unit and then engage it again.
6. Gradually feed the welding wire through the whole cable assembly until it emerges from the inlet nozzle
(101). Place welding wire in the groove of the drive roll and feed it into the liner nipple (102). Stop feed
when the welding wire emerges from the contact tip.
7. Fold in and lock pressure roll holder (20) and tension spring holder (14). Set the pressing force of the
holder or the counter-pressure roll using the adjusting screw (14a). The spring installed inside the
tension spring holder (14) determines the pressure. Turning the adjusting screw (14a) clockwise
increases the pressure. Turning the adjusting screw (14a) anti-clockwise reduces the pressing force of
the closed holder and/or the counter-pressure roll.
8. Finally close the cover (4).
