4.3 WIRE SPOOL POSITIONING
1. Open the unit side door to gain access to the spool compartment.
2. Unscrew the cap of the spool holder.
3. If necessary, fit an adapter for the wire spool.
4. Fit the spool in the spool holder, ensuring it is located correctly.
5. Adjust the spool holder braking system by tightening/loosening the
screw in such a way that the wire feed force is not excessive and
when the spool stops rotating no excess wire is released.
6. Refit the plug.
4.4 POSITIONING THE WIRE IN THE WIRE FEEDER
1. Lower the wire feeder pressure devices.
2. Raise the wire feeder pressure arms.
3. Check that the feed rolls are suitable for the wire gauge.
§ 15.3 WIRE FEEDER ROLLS

The diameter of the roll groovemust be compatible with the
diameter of the welding wire.

The roll must be of suitable shape in relation to the composition of
the wire material.

The groove must feature a "U" profile for soft materials
(Aluminium and its alloys, CuSi3).

The groove must be "V" shaped for harder materials (SG2-SG3,
stainless steels).

Rolls with a knurled groove profile are available for flux-cored
wire.
4. Feed the wire between the wire feeder rolls and insert it into the
MIG/MAG TORCH connector plug.
5. Make sure the wire is located correctly in the roll grooves.
6. Close the wire feeder pressure arms.
7. Adjust the pressure system so that the arms press the wire with a
force that does not deform it while also ensuring constant feed
rate without slipping.
8. Set the welding power source ON/OFF switch to “I” (unit
powered).
