Local controls R31, R32
potentiometer
MIG/MAG: Local control for wire feed speed
0...18 m/min or 0...25 m/min
SYNERGIC MIG: Power control, min. and
max. powers according to filler wires
SYNERGIC PULSED MIG: Power control, min.
and max. powers according to filler wires
MMA welding: Welding current control,
10 A...max. current of power source
potentiometer
MIG/MAG: local control for voltage of PRO power
source, 10 V...max. MIG voltage of power source
SYNERGIC MIG: Fine control for arc length
-9...0...9
SYNERGIG PULSED MIG: Fine control for
arc length -9...0...9
MMA welding: No operation
Control of welding dynamics R33
MIG and MMA welding dynamics are adjusted with the same potentiometer.
When you adjust welding dynamics the adjustment value -9...0...9 is shown in
display V, which otherwise shows set value/welding voltage. Value of dynamics is
shown in display still for approx. 3 s after stopping the adjustments.
Control of MIG/MAG welding dynamics:
With control of MIG/MAG welding dynamics you can influence on how stable the arc is and
how much spatter there is. With this control you can also optimize the welding result for wire
type and shielding gas mixture you are using.
-9...-1 Softer arc. Object: minimizing spatter
0 Recommendable basic setting for all wires
1...9 Harder arc. Object: e.g. maximizing stability of the arc on short circuit and
welding of steel with 100 % CO
2
shielding gas (settings 7...9).
Control of SYNERGIC MIG welding dynamics:
In SYNERGIC MIG the control of welding dynamics is optimized for wire type you are using.
With this control you can influence on stability of arc and how much spatter there is.
-9...-1 Softer arc. Object: Minimizing spatter
0 Recommendable basic setting
1...9 Harder arc. Object: e.g. maximizing stability of the arc on short circuit
NOTE! Control range for MIG welding dynamics -9...0...9 is a relative range according to wire
and is different from control range -9...0...9 for dynamics of normal MIG/MAG welding.
Shape of arc in SYNERGIC PULSMIG:
In SYNERGIC PULSMIG the control for welding dynamics has an influence on shape of pulsed
MIG arc.
-9...-1 Wider pulsed MIG arc. Object: e.g. welding of square butt preparation
0 Recommendable basic setting
1...9 More narrow and better directed arc. Object: e.g. fillet weld seams of thin
basic materials
