Loosen and lower the plastic knob (A) (Fig.4). Release the upper roll (B) of the feeder. Extract the wire from the torch liner.
√ √ √ √ √
When the wire is disconnected, grasp it with pliers so that it cannot exit from the spool. If necessary, straighten it before inserting it in the wire
input guide (C). Insert the wire on the lower roll (D) and in the torch liner (E).
WARNING: keep the torch straight. When feeding a new wire through the liner, make sure the wire is cut cleanly (no burrs or angles) and that
at least 2cm from the end is straight (no curves). Failure to follow these instructions could cause damage to the liner.
√ √ √ √ √
Lower the upper roll (B) and place the knob (A). Tighten slightly. If tightened too much, the wire gets locked and could cause motor damage. If
not tighten enough, the rolls will not feed the wire.
When changing the wire diameter being used, or replacing the wire feed roll, be sure that the correct
groove for the wire diameter selected is inside, closest to the machine. The wire roll is driven by the
inside groove. Feed rolls are marked on the side identifying the groove nearest that side.

Close the side panel of the machine. Connect the power supply cable to the power output line. Turn
on the switch. Press the torch switch. The wire fed by the wire feeding motor at variable speed must
slide through the liner. When it exits from the torch neck, release the torch switch. Turn off the
machine. Mount the contact tip and the nozzle.
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.
6.0 REPLACING THE WIRE LINER
Before performing this procedure, ensure the gas and electrical
supplies are disconnected.
√ √ √ √ √
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.
Warning: the lenght 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.
