5.3 Changing the inlet nozzle
The TBi PP-TX is equipped with an inlet nozzle (101, part no. 195P102052) that is designed for all permissible
welding wires (0.8-1.6 mm). It should be cleaned regularly with compressed air, checked for wear and replaced
if necessary.
Proceed as follows to replace:
1. If necessary, remove torch neck.
2. Open (4) cover, loosen tension spring holder (14) from locking device and fold upwards.
3. Open pressure roll holder (20) and fold to the side.
4. Remove any welding wire still in the torch or pull back as far as the cable assembly.

do not use any tools!

in the cable assembly.

cable assembly. Proceed as described under Section 3.3.6
