I / A display
MIG/MAG welding with independent controls for wire feed speed and voltage: Display shows 0
A before, and true value during welding.
SYNERGIC MIG welding: Display shows 0 A before, 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.
U / V display
MIG/MAG welding with independent adjustments for wire feed speed and voltage: Display shows
pre-set value for welding voltage, and true value during welding.
SYNERGIC MIG welding: Display shows pre-set value for welding voltage, and true value during
welding.
When adjusting arch length display shows voltage.
SYNERGIC PULSED MIG welding: In setting state, display shows set value -9...0...9 for arc
length, and true value of welding voltage during welding.
Note! Display shows terminal voltage of power source. Depending on length and copper cross-
section of welding cables real arc voltage and display may differ (see table below).
Cable
50 mm2 70 mm2 95 mm2
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 V shows adjustment value for welding dynamics
-9...0...9, the value is shown for approx. 3 s after end of adjustment. After that display reverts to
show voltage in SYNERGIC MIG and arc length in SYNERGIC PULSED MIG welding.
4.2.1. WELD DATA
Retrieval of welding parameters to displays
Use of WELD DATA switch retrieves 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 you are using the WELD DATA switch and are stored until you press again
the start switch of gun.
Testing the gas flow
A short press on the switch starts shielding gas flow. Shielding gas flows for approximately 20
seconds, or until the switch is pressed again.
