Loading the Electrode Wire
Turn the machine off.
Open the Right panel of the machine.
Unscrew the locking nut of the sleeve.
Load the spool with the wire on the sleeve such that
the spool turns anticlockwise when the wire is fed
into the wire feeder.
Make sure that the spool locating pin goes into the
fitting hole on the spool.
Screw in the fastening cap of the sleeve.
Put on the wire roll using the correct groove
corresponding to the wire diameter.
Free the end of the wire and cut off the bent end
making sure it has no burr.
WARNING
Sharp end of the wire can hurt.
Rotate the wire spool anticlockwise and thread the
end of the wire into the wire feeder as far as the Euro
socket.
Adjust force of pressure roll of the wire feeder
properly.
Adjustments of Brake Torque of Sleeve
To avoid spontaneous unrolling of the welding wire the
sleeve is fitted with a brake.
Adjustment is carried by rotation of its Allen screw M8,
which is placed inside of the sleeve frame after
unscrewing the fastening cap of the sleeve.

Turning the Allen screw M8 clockwise increases the
spring tension and you can increase the brake torque
Turning the Allen screw M8 anticlockwise decreases the
spring tension and you can decrease the brake torque.
After finishing of adjustment, you should screw in the
fastening cap again.

Adjusting of Pressure Roll Force
The pressure arm controls the amount of force the drive
rolls exert on the wire.
Pressure force is adjusted by turning the adjustment nut
clockwise
to
increase
decrease force. Proper adjustment of pressure arm
gives the best welding performance.
If the roll pressure is too low the roll will slide on the wire.
If the roll pressure is set too high the wire may be
deformed, which will cause feeding problems in the
welding gun. The pressure force should be set properly.
Decrease the pressure force slowly until the wire just
begins to slide on the drive roll and then increase the
force slightly by turning of the adjustment nut by one
turn.
Inserting Electrode Wire into Welding
Torch
Turn the welding machine off.
Depending on welding process, connect the proper
gun to the euro socket, the rated parameters of the
gun and of the welding machine should be matched.
Remote the nozzle from the gun and contact tip or
protection cap and contact tip. Next, straighten the
gun out flat.
Turn the welding machine on.
Hold the Cold Inch/Gas Purge Switch in the Cold
Inch position.
When the switch is released spool of wire should not
unwind.
Adjust wire spool brake accordingly.
Turn the welding machine off.
Install a proper contact tip.
Depending on the welding process and the type of
the gun, install the nozzle (GMAW process) or
protection cap (FCAW process).
Take precaution to keep eyes and hands away from the
end of the gun while the wire is being come out of the
threated end.
