Control of welding dynamics R23
When you adjust welding dynamics, adjustment value -9...0...9 is shown momenta-
rily in the Voltage display which normally shows set value / welding voltage. Value
of dynamics is shown in display for approx. 3 s after adjustment.
Control of MIG welding dynamics:
With MIG welding dynamics control you can influence arc stability.
-9...-1 Softer arc decreasing spatter
0
Default setting for all wires
1...9 Harder arc maximising stability of arc during short circuit and welding of steel with 100 %
CO2 shield gas (settings 7...9).
Digital display for wire feed speed, current and voltage P21, P22, P23
/ m / min display
Display shows set value of wire feed speed switching to true value 0.0...18.0 m/min or 0.0...25.0
m/min during welding.
A display
Display shows 0 A (*no welding*) switching to true value of welding current during welding.
V display
Display shows set value of welding voltage and true value 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.

4.1.1. WELD DATA / GAS TEST
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 for gun.
Testing the gas flow
A short press on switch starts flow of shielding gas. The shielding gas flows for approximately 20
seconds, or until the switch is pressed again.
