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
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).
