Control For Mma Welding Dynamics - Kemppi master 5001 Operation Instructions Manual

3.5. CONTROL FOR MMA WELDING DYNAMICS

MMA welding dynamics is controlled with potentiometer R22. The potentiometer R22 has the
reference scale -9...0...9 can be seen also on the V display P22, which otherwise is showing no-
load/welding voltage. Setups for dynamics remain on the display still for approx. 3 s after you
have finished the control.
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: eg cellulose covered electrodes (9) and thin stainless electrodes in welding
at lower end of recommended currents for electrode.
