OPERATING MANUAL
Welding parameters for Pulse MIG process (Edit channel 2/6)
Menu item Value range Default value Description
1/8 WFSpeed WFS min -
WFS max
From curve Set the wire feed speed in
0.05 m/min steps from 0.5 to
5.0 m/min and in 0.1 m/min
steps above 5.0 m/min.
2/8 WFS max 0.7 - 25.0 m/min * From curve Set the upper limit for the
WFSpeed value.
3/8 WFS min 0.7 - 25.0 m/min * From curve Set the lower limit for the
WFSpeed value.
4/8 FineTuning FineTuningMin
FineTuningMax-
0 Adjust the welding voltage
(arc length) of the welding
curve up and down (0 = no
adjustment).
5/8 FineTuningMax -9.0 … +9.0 +9.0 Set the upper limit for the
FineTuning value.
6/8 FineTuningMin -9.0 … +9.0 -9.0 Set the lower limit for the
FineTuning value.
7/8 Dynamics -9 … +9 0 Control the arc behavior in
short circuit. A lower value
results in a softer arc and
a higher value results in a
rougher arc.
8/8 Pulse current -10 … +15 % 0 % Adjust the pulse current up
and down.
* These are system limits. Actual limits come from the selected welding curve.
Welding parameters for Double Pulse MIG process (Edit channel 2/6)
Menu item Value range Default value Description
1/10 WFSpeed WFS min -
WFS max
From curve Set the wire feed speed in
0.05 m/min steps from 0.5
to 5.0 m/min and in 0.1 m/
min steps above 5.0 m/min.
2/10 WFS max 0.7 - 25.0 m/min * From curve Set the upper limit for the
WFSpeed value.
3/10 WFS min 0.7 - 25.0 m/min * From curve Set the lower limit for the
WFSpeed value.
4/10 FineTuning FineTuningMin -
FineTuningMax
0 Adjust the welding voltage
(arc length) of the welding
curve up and down (0 = no
adjustment).
5/10 FineTuningMax -9.0 … +9.0 +9.0 Set the upper limit for the
FineTuning value.
6/10 FineTuningMin -9.0 … +9.0 -9.0 Set the lower limit for the
FineTuning value.
7/10 Dynamics -9 … +9 0 Control the arc behavior in
short circuit. Lower value
results to softer and higher
value to rougher arc.
8/10 Pulse current -10 … +15 % 0 % Adjust the pulse current up
and down.
9/10 DPulseAmp 0.1 - 3.0, CURVE CURVE Adjust the amplitude of
the wire feed speed, or use
the value from the welding
curve.
10/10 DPulseFreq 0.4 - 8.0 Hz, CURVE CURVE Adjust the frequency of
the double pulse, or use
the value from the welding
curve.
* These are system limits. Actual limits come from the selected welding curve.
