5.11.3 Outlet wire guide
1. Remove the lower right feed roller
(see the "Changing feed rollers"
section).
2. Remove the middle wire guide (see
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. Install the correct outlet wire guide
(according to the WEAR PARTS
appendix).
6. Lock the new outlet wire guide using
the wire guide quick lock (A).
7. Reattach the second pair of feed
rollers and reapply the roller
pressure (see the "Changing feed
rollers" section).
5.12 Roller pressure
The roller pressure should be adjusted separately on each tensioner unit, depending on used
wire material and diameter.
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 (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. In case of long, dirty or worn torch
cables, the pressure setting may have to be increased. Always check the roller pressure
setting in each specific case 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.
