To replace liner: Disconnect gun/cable

assembly at the Euro adaptor. Remove

nozzle (1) gas diffuser (3) and insulator (4).

Withdraw old liner from the wirefeeder

end. Insert new liner and refit gun/cable

assembly to the wirefeeder.
At the gun end, compress the liner within

the gun cable, then cut it approx 20mm

past the end of the body tube/neck (5).
Refit insulator and screw gas diffuser on

firmly with a wrench.
Insert tip (2) into gas diffuser then thread

nozzle onto gas diffuser/tip and tighten

firmly by hand.
