Connection and operation
Change of wire liner
Welding in aluminium
and MIG brazing
requires a special teflon
liner.
Use article no. 81100137
to order kit for
aluminium and MIG
brazing in 1.0 mm wire
with wire liner and inlet
guide.
Wire drive rolls
The welding machine is supplied
with turnable wire drive rolls with
V-groove.
For aluminium welding and MIG
brazing, we recommend U-groove/
article no. 82046232.
Selecting welding polarity
Polarity reversal is recommended for certain types of
welding wire, in particular Innershield welding wire. For
recommended polarity, please refer to the welding wire
packaging.
Change of polarity:
1. Disconnect the machine from the mains supply.
2. Dismount the milled nuts at the poles (fig. 1).
3. Reverse the cables (fig. 1).
4. Mount the milled nuts (fig. 1).
5. Exchange earth cable from minus to plus (fig. 2).
6. Connect the machine to the mains supply.

Material consumption
Material consumption can be estimated by calculating
welding time in minutes times wire feed speed (m/min)
times weight per meter of the welding consumables in use.
2
Inching
The function is used for wire inching
e.g. after change of wire. Wire inching
starts by pressing the green key pad and
simultaneously triggering the torch trigger.
Wire inching continues even though the
green key pad has been released. It does
not stop until the torch trigger has been released again.
Switch on, press, weld
Welding program setting

• Set one of the following parameters:
welding current, wire feed speed or thickness of material
• Trim the arc length, if required
• Adjust secondary parameters.
• The machine is now ready to weld
WARNING
Voltage is present on the welding wire/electrode
when pressing the welding hose trigger
Software reading
• Insert the SD-card (<2 GB) in
