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 pressure roller(s). 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
roller(s) 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
S
Open the side panel.
S
Disconnect the pressure sensor by folding it backwards, the pressure rollers
slide up.
S
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 feed unit.
S
Make sure that the wire goes properly into the feed roller track and into the outlet
nozzle and the wire guide.
S
Secure the pressure sensor.
S
Close the side panel.
6.5 Overheating protection
A thermal overload cutout protects against overheating. The cutout resets automatically
when the unit has cooled.
6.6 Inductance connection
Higher inductance produces a more flowing weld and fewer spatters. Lower inductance
produces a harsher sound and a stable, concentrated arc.
