Control of MMA dynamics:
With control of MMA dynamics you can influence on arc in different situations.
When you make the arc harder, blow and at the same time spatter is increased.
-9...-1
Softer arc. Object: Minimizing spatter in welding at upper end of recommended
currents for electrode.
0
Factory setup. Normal setting for all electrode types.
1...9
Harder arc. Object: e.g. cellulose covered electrodes (9) and thin stainless
electrodes in welding at lower end of recommended currents for electrode.
Digital display for wire feed speed, current and voltage P31, P32, P33
/m/min display
MIG/MAG with independent controls for wire feed speed and voltage: Display shows set
value for wire feed speed and true value 0.0...18.0 m/min or 0.0...25.0 m /min during welding
depending on selection of wire feed speed range.
SYNERGIC MIG welding:
Display shows set value for wire feed speed and true value during welding.
Wire feed speed range is a wire type min. and max. speed.
SYNERGIC PULSED MIG welding:
Display shows set value for wire feed speed and true value during welding.
Wire feed speed range is a wire type min. and max. speed.
MMA weldig:
Display is blank at MMA welding.
I/A display
MIG/MAG welding with independent controls for wire feed speed and voltage: Display shows
in setting state 0 A and true value during welding.
SYNERGIC MIG welding:
Display shows in setting state 0 A and true value during welding.
SYNERGIC PULSED MIG welding:
Display shows in setting state the reference mean current value and true value for welding
current during welding.
MMA welding:
Display shows set value for MMA welding current 10 A...max. current of power source and
true value during welding.
U/V display
MIG/MAG welding with independent adjustments for wire feed speed and voltage: Display
shows set value for welding voltage and true value during welding.
SYNERGIC MIG welding:
Display shows set value for welding voltage and true value during welding.
By adjustment of arc length in display is shown adjustment value -9...0...9 for arc length, which
is kept in display still for 3 s after end of adjustment.
SYNERGIC PULSMIG welding:
Display shows in setting state value -9...0...9 for arc length and during welding true value of
welding voltage.
MMA welding:
Display shows in setting state open circuit voltage of power source and true value for MMA
welding voltage during welding.
