Loading the Electrode Wire
Depending on the type of wire spool it can be installed on
the wire spool support without adapter or installed with use
applicable adapter that must be purchased separately
(see "Accessories" chapter).
WARNING
Turn the input power OFF at the welding power source
before installation or changing a wire spool.

Turn the machine off.

Open the side cover 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.

The device is adapted to the spool max. 300mm
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.

33. Pressing spring.
Turning the Allen screw M8 anticlockwise increases the
spring tension and you can increase the brake torque
Turning the Allen screw M8 clockwise 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 Force 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 force, counterclockwise to decrease
force. Proper adjustment of pressure arm gives the best
welding performance.
WARNING
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.

Push the Cold Inch Switch [12] to feed the wire through
the gun liner until the wire comes out of the threaded
end.

When 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).
WARNING
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.
