6.3 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 great.
Fig 1 Fig 2
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
rollers 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).
6.4 Replacing and inserting wire
WARNING
Risk of crushing! Do not use safety gloves when replacing wire, feed rollers
and wire bobbins.
S Open the side panel.
S Disconnect the pressure sensor by folding it backwards, the pressure arm is
folded up.
S Straighten out 10-20 cm of the new wire. File away burrs and sharp edges from
the end of the wire before inserting it into the wire feed unit.
S Make sure that the wire goes properly into the feed roller's track and into the
outflow nozzle or wire guide.
S Fold down the pressure arm and secure it to the pressure sensor.
S Close the side pannel.
