CONNECTION OF TERMINATING RESISTORS

Abbrevations used in this chapter
MMC = Man Machine Communication
The MMC unit is a control panel with display, in some cases it also incorporates a welding
data board, see WDU below.
WDU = Welding Data Unit.
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.
Symbol explanation
Fixed terminating resistor on circuit board =
Terminating resistor on circuit board, disconnected =
Terminating resistor on circuit board, connected by a jumper =
The welding data unit of MMC unit A24 has no terminating resistor.
