Wire feed pressure
Start by making sure that the wire moves smoothly through the wire guide. Then set the
pressure of the wire feeder's pressure rollers. It is important that the pressure is not too high.
Figure A
Figure B
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 welding torch approx. 5 mm from the piece of wood (figure A) the feed
rollers should slip.
If you hold the welding torch approx. 50 mm from the piece of wood, the wire should be fed
out and bend (figure B).

Replacing and inserting wire
1.
Open the side panel.
2.
Place the spool on the hub and secure it with the lock.
3.
Disconnect the pressure arm by folding it sidewards, the pressure roller slides away.
4.
Straighten out the new wire 10-20 cm. File away burrs and sharp edges from the end
of the wire before inserting it into the wire feeder.
5.
Make sure that the wire goes properly into the feed roller groove and into the outlet
nozzle and the wire liner.
6.
Secure the pressure arm.
7.
Close the side panel.
Feed the wire through the welding torch until it comes out through the nozzle. This operation
should be carried out carefully, as the wire is ready for welding and an 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.
See "TECHNICAL DATA" chapter for suitable wire dimensions for each wire type.
Use only Ø200 mm spools.
NOTE!
Ø100 mm/1 kg spools are not applicable.
WARNING!
Do not keep the torch near the ears or the face during wire feeding, as this
may result in personal injury.
