Wire feed pressure

Start by making sure that the wire moves smoothly through the wire guide. Then
set the pressure of the wire feeder pressure roller(s). It is important that the
pressure is not too great.
Fig 1
To check that the feed pressure is set correctly, you can feed out the wire against
an insulated object, e.g. a piece of wood.
When you hold the gun approx. 5 mm from the piece of wood (fig. 1) the feed
roller(s) should slip.
If you hold the gun approx. 50 mm from the piece of wood, the wire should be
fed out and bend (fig. 2).

Replacing and inserting wire

To prepare the machine, a spool with wire should be installed. See technical data for
suitable wire dimensions for each wire type.
Use only 200mm spools.

Place the spool on the hub and secure it with the lock.

Disconnect the pressure arm by folding it sidewards, the pressure roller slides
S
away.
Straighten out the new wire 10--20 cm. File away burrs and sharp edges from the
S
end of the wire before inserting it into the wire feed unit.
Make sure that the wire goes properly into the feed roller track and into the outlet
S
nozzle and the wire guide.
Secure the pressure arm.
S
Close the side panel.

Feed the wire through the welding torch until it comes out of the current tip. This
operation should be carried out carefully, as the wire is on the welding potential and
unintentional arc may occur. Keep the torch off conducting parts during feeding the
wire through and terminate wire feeding instantly when the wire comes out of the
current tip.
