• Loosen and lower the plastic knob (A). 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 1/2" 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 tightened enough, the rolls will not feed the wire. NOTE:
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 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 outlet. 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. NOTE: When checking the correct exit of
the wire from the torch do not bring your face near the torch. You may run the risk of being
wounded by the outgoing wire. Do not bring your fingers close to the feeding mechanism
when working! The rolls, when moving, may crush fingers. Periodically check the rolls.
Replace them when they are worn and compromise the regular feeding of the wire.
Replacing the Wire Liner
BEFORE PERFORMING THIS PROCEDURE, BE SURE THE GAS SUPPLY LINE AND
INPUT POWER CABLE ARE DISCONNECTED.
• Disconnect the torch from the machine.
• Place it on a flat surface and carefully remove the brass nut.
• Pull the liner out of the hose.
• Install the new liner and mount the brass nut again.
In case you are replacing a Teflon or graphite wire liner, follow these
instructions:
• Install the new liner and insert the wire liner collet and the
O ring.
• Mount the brass nut.
• Cut the wire liner close to the brass nut NOTE: The length of the new wire liner must be the
same as the liner you have just pulled out of the hose.
• Connect the torch to the machine and install the wire into the feeding system.
How to Choose the Wire Liner for Direct and Euro Connect Torches
There are basically two types of wire liners: Steel and Teflon. Steel wire liners can be coated or non-
coated. Coated wire liners are used for air-cooled torches. Teflon wire liners are recommended for
aluminum welding as they allow smooth feeding of the wire.
