or welding current (MMA).
10 Setting welding voltage, Arc
adjust and welding process
Turn the control knob to set the desired
welding voltage or Arc adjust (see table 1).
Short press (MIG/MAG): Change between
display of welding voltage and Arc adjust.
Long press: Opens for setting the welding
process (see figure 1).
11 MIG/MAG welding with Argon
(Ar)/mix gases
12 MAG welding with CO
13 Selecting trigger mode
Change between 2-stroke (indicator off)
and 4-stroke (indicator on).
2-stroke: The welding process starts when
the torch trigger is activated and ends
when the torch trigger is released.

14 MMA welding
Press the key to choose MMA welding.
Subsequent press recalls seam average
(welding current and voltage) for the latest
welding.
Long press recalls factory settings if
indicator is on.
15 MIG/MAG welding
Press the key to choose MIG/MAG
welding. Subsequent press recalls seam
average (welding current and voltage) for
the latest welding.
Long press changes between the two gas
types and recalls factory settings.
For optimum welding quality choose:

16 Watercooling (not all versions)
Indicator is on when watercooling of
torch is activated. See more details in
instruction manual.
17 Internal/external adjustment
When external adjustment is chosen, the
indicator is on.
For special configuration, see instruction
manual.
18 Wire inching
Press the key to feed the wire and adjust
the wire feed speed by turning (13)
simultaneously.
19 Gas test
