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.
6.1.3 REPLACING THE WIRE LINER
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.
• In case you are replacing a Teflon wire liner, follow
these instructions:
• Install the new liner followed by the collet (3).
• Insert the O ring (4) on the wire liner collet (4)and re-
place 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.
6.1.4 HOW TO CHOOSE THE WIRE LINER

• 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.

For safety, and economy, ensure that the regulator is fully closed, (turned counter-clockwise) when not welding
and when fitting or removing the gas cylinder.
• Turn the regulator adjustment knob counter-clock wise to ensure the valve is fully closed.
• Screw the gas regulator fully down on the gas bottle valve, and fully tighten.
• Connect the gas hose to the regulator securing with clip/nut provided and to the connector on the
back (12).
• Open the cylinder valve, then set the gas flow to approx. from 5 to 15l/min. on the regulator.
