Control of welding dynamics R23
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 welding dynamics:
With control of MIG 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 MMA dynamics:
With control of MMA dynamics you can influence on arc in different situations.
When you make the arc harder, blow and at the same time spatter is increased.
-9...-1 Softer arc. Object: Minimizing spatter in welding at upper end of recommended
currents for electrode.
0 Factory setup. Normal setting for all electrode types.
1...9 Harder arc. Object: e.g. cellulose covered electrodes (9) and thin stainless electrodes
in welding at lowerend of recommended currents for electrode.
Digital display for wire feed speed, current and voltage P21, P22, P23
m/min display
MIG welding:
Display shows set value for wire feed speed and true value 0.0...18.0 m/min or 0.0...25.0 m/min
during welding depending on selection of wire feed speed range.
MMA welding:
Display is blank at MMA welding.
A display
MIG welding:
Display shows in setting state 0 A and true value for welding current during welding.
MMA welding:
Display shows set value for MMA welding current 10 A ...max. current of power source and
true value during welding.
V display
MIG welding:
Display shows set value for welding voltage and true value during welding.
MMA welding:
Display shows in setting state open circuit voltage of power source and true value during
welding for MMA welding voltage.
