7.0 REPLACInG THE WIRE LInER
Before performing this procedure, ensure the gas and electrical supplies are di-
sconnected.
• Open the side panel. Loosen and lower the plastic knob (A) and release the pressure arm (B) (Fig.
5). Cut the wire (in the case it is installed) grasp it with pliers so that it cannot exit from the spool
and fix it on the suitable hole in the reel. Remove the nozzle and contact tip. Remove with pliers
the wire from the hose and torch assembly.
When checking the correct exit of the wire from the torch do not bring your face
near the torch, you may run the risk to be wounded by the outgoing wire. Do not
bring your fingers close to the feeding mechanism when working! The rolls, when
moving, may crush the fingers. Periodically, check the rolls. Replace them when
they are worn and compromise the regular feeding of the wire.

fig.6:
• Disconnect the torch from the machine.
• Place it on a flat surface and carefully remove the
brass nut (1).
• Pull the liner out of the hose.
• Install the new liner and mount the brass nut (1)
again.
• In case you are replacing a Teflon wire liner, fol-
low these instructions:
• Install the new liner and install the collet on the
wire liner (3).
• Insert also the O ring (4) on the wire liner collet
(3) and replace the brass nut (1).
• Cut the wire liner close to the brass nut
Warning: the length of the new wire liner must be the same of the liner you have
just pulled out of the hose.
• Connect the torch to the machine and install the wire into the feeding system.
7.1 HOW TO CHOOSE THE WIRE LINER
Mainly we can have 2 types of wire liners: Steel wire liners and Teflon wire liners.
• The steel wire liners can be coated or not coated: the coated wire liners are used for air cooled torches;
the wire liners which are not coated are used for water cooled torches.
• The Teflon wire liners are suggested for the welding of Aluminium, as they allow a smooth feeding
of the wire.
