Selection of material type
Press the -key pad until the indicator for the
required material is switched on.
Selection of wire dimension
Press the -key pad until the indicator for the
required diameter is switched on.
Not all wire dimensions can be used for all
materials.
Selection of AlMg5/AlSi programs:
1. Select material the material type "Al".
2. Select material type 1.0 or 1.2mm.
3. Keep the material key pressed for 5 sec until the
"Al" LED is switched off as indication of entrance to
set-up mode. The display shows
352 (1.0 mm AlSi ER4043) or
312 (1.0 mm AlMg5 ER5356) if 1.0 mm wire has
been selected, or
353 (1.2 mm AlSi ER4043) or
313 (1.2 mm AlMg5 ER5356) if 1.2 mm wire has
been selected.
4. Turn the encoder back and forth until the correct
program is displayed
5. The program is selected by one more press on the
material key knob, and the machine will return to
normal mode.
Reset to factory settings:
Factory settings for the selected wire dimension will be
reloaded when pressing the key pad until the indicator
gives a short flash.

Current/wire feed speed/material
thickness:
When the machine is not welding, the set
current/ wire feed speed/material dimension
is displayed. During welding the measured
current is displayed.
Material thickness:
The function helps adjusting the current according to
material thickness (in mm). When selecting material
thickness an automatically setting of current is
calculated. Thereafter, the current can be further
adjusted. The material thickness function can be seen
as a good starting point in the selection of correct
current and voltage. A trimming of these parameters
will be required in almost every welding task in order
to obtain the most optimum result.
Arc length
If necessary, the arc length can be
adjusted by trimming the voltage. The
measured voltage is shown during welding. Press the
-key pad and adjust from –9,9 to +9,9.
Control knob
This knob is used for adjusting welding
current, wire feed speed, material
thickness, arc length or secondary
parameters. Inching speed is adjustable
during wire inching. Max. wire feed speed is
18.0 m/min.
Trigger mode
When the indicator is on, 4-times has been
selected and when the indicator is off, 2-times
has been selected. Trigger mode cannot be changed
during welding.
2-times:
Welding starts when the torch trigger is held down. To
end welding, the torch trigger is released and burn
back starts. It is possible to trigger the machine again
during post flow.
4-times:
Welding starts when the torch trigger is held down.
The trigger can then be released and welding
continues. To end welding the torch trigger is held
down again and burn back starts.
Pulse welding
MIG pulse welding on/off.
Setting of secondary parameters
Press the control knob until the requested
parameter is displayed. To return to normal
display the key pad for arc length or
current/wire feed speed/material thickness is to
be pressed briefly.
Arc adjust:
Arc-adjust (electronic choke) makes it possible
to adjust the speed of reaction to short-circuits.
Arc-adjust can be set in steps from –5.0 to +5.0.
