2.5 POSITIONING THE WIRE IN THE WIRE FEEDER

1. Lower the wire feeder pressure devices.
2. Raise the wire feeder pressure arms.
3. Remove the protective cover.
4. Check that the feed rolls are suitable for the wire
gauge.
§ "15.5 WIRE FEEDER ROLLS"
• The diameter of the roll groove must 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 be "U" shaped 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.
5. Feed the wire between the wire feeder rolls and
insert it into the MIG/MAG TORCH connector
plug.
6. Make sure the wire is located correctly in the roll
grooves.
7. Close the wire feeder pressure arms.
8. 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.
9. Refit the protective cover.
10. Set the welding power source ON/OFF switch to
"I" (unit powered).
11. Feed the wire through the torch until it protrudes
from the tip, pressing button
panel.
