5.5 Installing the wire guide
Choose the wire guide or liner depending on the filler wire material and diameter to be used,
see the spare parts list. Accurate performance of the system can only be guaranteed when
using original ESAB wire guides.
The recommended wire guide is the split wire guide, which consists of the neck liner and a
separate guide in the cable assembly. The front part of the wire guide, which is most
stressed, can be exchanged easily and independently of the cable assembly wire guide.
For correct installation, the following steps must be followed (example for Euro central
connector):
5.5.1 Installing the neck liner
The neck liner must be selected to fit the material and diameter of the welding wire, see the
spare parts list.
1. If present, remove the central guide nipple (1), from the torch neck using a hexagon
wrench (size 6 mm) or a large flat-blade screwdriver.
NOTE!
The guide nipple (1) can only be used with one-piece liners and must not be
used with the standard RT or hollow wrist system.
2. When replacing the neck liner:
Unfasten the sleeve nut and remove the torch neck.
Unfasten the liner nipple using a hexagon wrench (size 6 mm) and remove nipple and
liner from the torch neck.
3. Remove the gas nozzle and the contact tip.
4. Insert the new neck liner (2) into the torch. Carefully tighten the guide nipple using a
suitable tool, e.g. a hex-wrench (size 6 mm) or a large flat-blade screwdriver.
5. Cut the neck liner flush with the tip holder and remove the neck liner from the torch.
6. Install the contact tip.
