MMA DC Process

In section Q - fig. 4 of the main screen, select DC
8�2

MMA AC Process

In section Q - fig. 4 of the main screen, select AC
In the MMA AC this process, the output current frequency is 50 Hz and the output waveform is square.
Frequency and waveform are fixed and unmodifiable, unlike the TIG AC process.

MMA DC/AC process parameters

Description
Hot Start
Improves ignition even when using electrodes with poor ignition
properties
Arc Force�
0 voltaic arc with little spatter, barely defined
100 voltaic arc with spatter, but stable
Hot start time�
To be adjusted according to the diameter of the electrode to be
welded.
Antistick�
Function that prevents the electrode from bonding to the
workpiece
Cut off Voltage�
Arc cut-off voltage. Once the set voltage is reached, the arc
is extinguished, avoiding optical flashes and preserving the
electrode for subsequent ignitions.
VRD�
This function reduces power source no-load voltage, required
in environments with a high explosion risk.
