5. Remove the wire guide again and shorten the front end by the measured length.

Steel liner: grind down the burred edges if needed.

Plastic liner: make a clean cut and chamfer the edges (e.g. with a pencil sharpener)

NOTE!

Make sure the inner opening of the liner is not obstructed by the cut wire end.

6. Reinstall the wire guide and attach the sleeve nut (2).

NOTE!

For hollow wrist systems where Infiniturn and Helix cable assemblies are

used, wire guides should be installed without tension so that the ends of the

liners may rotate freely.

Important note when using a plastic liner:

The wire channel between the drive rolls of the feeder and the central

connector of the torch must be fitted with a plastic liner. Depending on the

design of the feeder, a piece of plastic liner inserted into a brass guide tube

can be used.

During wire run-in, make sure that the wire is fed correctly into the plastic

liner of the torch. If necessary, remove the cable assembly from the feeder

and insert the wire, then reattach.

5.6 Installing the torch

Be sure to use the correct version of the torch mount and cable assembly (water or gas

cooled).

5.6.1 Torch neck equipment

The torch neck, see (1) in the illustration below, must always be equipped to suit the wire

diameter and material.

1. Select the correct wire guide, contact tip (4), tip holder (2), gas nozzle (5), and gas

diffuser/spatter protection (3). You will find an exact overview and possible alternative

equipment elements for various torch models in the spare parts list. Only use original

ESAB parts; only then is the fitting accuracy ensured.

2. Firmly tighten the tip holder and the contact tip using a suitable tool for example the

enclosed monkey wrench.

3. When using a split wire guide, remove the installed guide nipple including the o-ring from

the torch flange upon delivery if necessary (see section "Installing the neck liner").

CAUTION!

The torch must be completely equipped before welding, especially the gas

diffuser and/or spatter protection and all necessary insulators have to be

installed according to the spare parts list. Welding without these items may

cause immediate destruction of the torch.
