Welding control

The welding controller takes over the task of setting the time and power for the welding machine or device. It consists of a time control unit, a power control unit, the power supply and the control panel. The welding control system is characterised by the fact that the operating unit, the interface for man-machine communication, is integrated. Controls without integrated operation are called welding modules. But more about that in the next lexicon.

Today’s welding controllers all work digitally and synchronously with the mains. The differences in the functions of modern control systems lie in the number of programmes, the range of functions and the way they are operated. The inputs and outputs of the controller can either be designed as 24 V inputs and outputs for direct wiring with a higher-level controller or the operating elements, or with a fieldbus interface for communication with the PLC or the robot.

The operation is mostly adapted to the requirements of the applications. Controls for standard machines are usually very simple so that programmes or parameters can be changed quickly and easily. For special machines, special larger displays with touch operation are often integrated in order to still meet the high demands of process technology in an easy and manageable way. Examples of welding controls with simple operation for standard machines are the MPS 10 or the Filius control series.
