Adjust The Narrow Gap Contact Tip - ESAB RT KS-2 Instruction Manual

5 INSTALLATION
Installing a plastic liner
1. Mount the torch neck (see section "Torch neck equipment") and equip it with a gas
nozzle and contact tip.
2. Remove the sleeve nut (D) from the Euro connector.
3. Cleanly cut off the liner, slightly break the outer edges, point slightly (e.g. with a pencil
sharpener).
4. Insert the liner through the central connector into the cable assembly with fitted torch.
If it gets stuck, rotate the liner to free it and facilitate installation.
NOTĂ!
Make sure the liner is completely inserted by rotating it and slightly pushing it
forward, until you can feel it has reached its stop.
5. Mount the nipple (B) and the O-Ring (C), move it to the right position and fix it with the
sleeve nut (D) of the Euro central connector.
6. Measure the required overlap needed inside the wire feeder cabinet and cut the liner
accordingly.

Adjust the narrow gap contact tip

The adjusting tool RT 42-NG is designed for the narrow gap torch necks RT 42W-NG,
RT 42G-NG and RT 82W-0° NG, torches with curved narrow gap contact tip. It facilitates the
precisely repeatable and fast changing of the curved contact tip.
NOTĂ!
The adjusting tool must be securely fastened to a stable base, in order to prevent
the position of the device in relation to the robot cannot change unintentionally. If the
exact orientation of the device is lost, the alignment of the contact tip used for the
elaboration of the welding programs can no longer be reproduced with precision.
Select a position within the operating range of the robot for orientation (alignment) of the
contact tip to the torch. Fasten the adjusting tool firmly to a base using the fastening grooves
provided for this purpose. Fastening material is not included with the adjusting tool. Select
fastening material (screws) to suit the existing conditions.
Save all motion sequences and stop positions required to change or align the wearing parts
to a separate robot program.
Before programming the welding tasks: plan at which orientation the contact tip is to stand in
relation to the torch. The torch must then be positioned in the desired rotational position and
the contact tip aligned using the adjusting device. Only then may the welding task be
programmed. If different orientations of the contact tip are required for various welding tasks,
the contact tip has to be aligned to the new position when the welding task is changed.
AVERTIZARE!
The gas nozzle and the torch head become very hot during welding. Always allow
the torch to cool down before replacing wearing parts or adjusting the contact tip.
