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 2 cm from the end is straight
(no curves). Failure to follow these instructions could cause damage to the liner.
WARNING: 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.
When loading wire and watching for it to come through the torch neck, to avoid inju-
ry, do not hold the torch close to your face, instead, direct the wire toward the floor.
To avoid injury, do not place fingers near the wire feed rolls when the wire feeder is
operating.
7.1.3 REPLACING THE WIRE LINER
Ensure the gas and electrical supplies are di-
sconnected.
•
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
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.
7.1.4 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.

7.1.5 GAS CYLINDER AND REGULATOR CONNECTION
WARNING: Cylinders are highly pressurized. Handle with care. Serious accidents can
result from improper handling or misuse of compresses gas cylinders. Do not drop
the cylinder, knock it over, expose it to excessive heat, flames or sparks. Do not strike
it against other cylinders.
The gas cylinder (not supplied) should be located at the rear of the welder, in a well ventilated area and securely
fixed to the work bench or to the wall to insure that it will not fall.For safety, and economy, ensure that the regulator
is fully closed, (turned counter-clockwise)when not welding and when installing or removing the gas cylinder.
•
Turn the regulator adjustment knob counter-clock wise to ensure the valve is fully closed.
•
Install the gas regulator on the gas cylinder, tighten the connecting nut firmly to insure against gas
leakage.
•
Connect the gas hose to the gas regulator.
•
Open the cylinder valve, then set the gas flow to approx. from 5 to 15l/min. on the regulator.
