the "Middle wire guide" section).
3.
Unlock the outlet wire guide quick
lock (A) by folding it out.
4.
Remove the outlet wire guide (B).
5.

5.12
Roller pressure
The roller pressure should be adjusted separately on each tensioner unit, depending on the
material and diameter of the wire used.
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 (0.2 in.) from the piece of wood (figure A) the
feed rollers should slip.
If you hold the welding torch approx. 50 mm (2 in.) from the piece of wood, the wire should
be fed out and bend (figure B).
The table below serves as a guideline showing approximate roller pressure settings for
standard conditions with correct bobbin brake force. If the torch cables are long, dirty or
worn, the pressure setting may need to be increased. Always check the roller pressure
setting on a case-by-case basis by feeding out the wire against an insulated object as
described above. A table showing approximate settings can also be found on the left side
inside the wire feeder.
