The welding controller MPS10 is a programmable 5-time controller for the control of 1-phase welding machines with up to eight welding programmes.

All operating functions of the MPS10 control stage are handled via a clearly arranged control panel. The use of standardised icons for resistance welders results in a user-friendly, language-independent interface.

All necessary controls for editing and configuration are located on the front panel. The electrical connections required for operation are located on the rear panel.

The basic features and functionalities of the controller are:

• Five-time control (VHZ, SZ, NHZ, OHZ, PZ) and additional SAZ as well as pulses
• Selectable operating modes single point and serial point
• Eight programmes
• Two start inputs
• Two solenoid valve outputs and one pre-stroke output
• Automatic 50/60 Hz detection
• Automatic compensation of mains voltage fluctuations
• Adaptation of the control system and welding sequences to the conditions of the welding system
• Display of status and error messages during the welding process
• with/without power switchover via button
