The MMC unit is a control panel with display, in some cases it also incorporates a welding
data board, see WDU below.
WDU

U
nit.
The welding data unit handles the overall control of the system. The WDU is a part of the
system software.
In MIG applications it is run by a separate processor on a separate board, named the
welding data board. The welding data board is enclosed in the MMC unit.
In MMA and TIG applications the WDU uses a part of the processor of the power source
control board.
