Note! Display shows terminal voltage of power source. Depending on length and copper cross-
section of welding cables as well as on that of MIG guns real arc voltage and display might
differ many volts from each other, see table below.
Cable 50 mm 2 70 mm 2 95 mm 2
Voltage loss / 10 m 0,35 V / 100 A 0,25 V / 100 A 0,18 V / 100 A
When you adjust welding dynamics, display shows adjustment value for welding dynamics
-9...0...9 and value is kept on display still for approx. 3 s after end of adjustment. After that
display is recalled to show voltage in SYNERGIC MIG and MMA welding and arc length in
SYNERGIC PULSED MIG welding.
3.2.1. WELD DATA
Retrieval of welding parameters to displays,
Use of WELD DATA switch retrieves to displays those welding parameters, wire feed speed,
welding current, welding voltage which were used when welding was stopped last. Welding
values are indicated in display for so long as you are using the WELD DATA switch and are
kept in memory until you press again the start switch for gun.
Testing the gas flow
A short press on the switch starts the flow of the shielding gas. The shielding gas flows for
approximately 20 seconds, or until the switch is pressed again.
3.2.2. SYNERGIC operations, ML panel
In SYNERGIC operation the operator tells the equipment the filler wire type and diameter which
are used and the equipment generates on basis of these data optimal welding characteristics
for wire in question. In SYNERGIC state adjustment for wire feed changes as adjustment for
welding power and adjustment for voltage changes as adjustment for arc length (so called ”one
knob adjustment”).
In SYNERGIC operation there are three operation modes:
Normal MIG/MAG welding with independent adjustments for wire feed
speed and voltage.
SYNERGIC operation is not in use.
SYNERGIC MIG welding with parameters which are optimized according to filler
wire parameters. Nine SYNERGIC MIG programs for different filler wires are
stored:
