Installing a plastic liner
1. Remove the sleeve nut from the
central connector, remove the gas
nozzle, contact tip and tip holder
from the torch.
2. Insert the liner through the central
connector and lock it with the sleeve
nut.
3. Gently push back the front part of
the liner into the torch as far as it will
go, do not apply force. Mark the end
of the torch neck on the liner.
4. Cut the liner to the correct length
using a projectile "X" measured from
the marking as shown in the figure.
Slightly chamfer the liner front end
after the liner has been cut to the
correct length.
If it is difficult to insert the liner into the torch,
make a clean cut at the front end of the liner
and chamfer the edges (e.g. with a pencil
sharpener).
Install all equipment parts on the torch neck.

Welding torch Projectile "X"
PSF 260C 13 mm
PSF 415C, PSF 415C RS3 9 mm
PSF 420Cw, PSF 420Cw RS3 9 mm
6.5 Cleaning the swan neck
• Clean the inside of the gas nozzle regularly to remove welding spatter and spray with
ESAB® anti-spatter agent.
• Check the consumables for visible damage and replace if necessary.
6.6 Checking the cooling system
Make sure that the cooling liquid is clean, change it if required. Impurities in the cooling liquid
can obstruct the torch water channels. Always use suitable cooling fluid for torches with
corrosion inhibitors.
NOTE!
If the liner has a bronze front end, first cut the plastic liner to a suitable length and
let the bronze liner stick out approximately 40-50 mm from the torch neck. Attach
the bronze liner to the front of the plastic liner and only then cut this liner
assembly to the precise length.
