DESCRIPTION OF OPERATION
This function description describes the function of circuit boards and other components in
the power unit. It is divided into sections, numbered to correspond to the circuit board
numbers and divisions into function blocks.
AP2 Interference suppressor board
Component positions and circuit diagram for circuit board AP2
The circuit board removes interference signals.
1 MMC module
The MMC module consists of an operator ’s control panel and a welding data board.
The power unit, the wire feed unit and the control panel each have their own
microprocessor for control, with the control panel being the central unit in the system. In
addition to storing and issuing welding data, it also exercises overall control of the system
as a whole.
Setting the welding data
Man--machine communication (MMC) is assisted by the modular architecture of the Aristo
range. It is possible to choose systems with the emphasis on the simplest possible
operation, or those that can provide more optimised settings for the best welding
performance.
The MMC modules are described in separate service manuals
