SPATZ+ / ServoSPATZ+ Inverter for Medium Frequency Welding

Our 1 000 Hz MF inverters have been specially developed for use in the automotive industry and are available as 400, 600 and 900 amp versions. The inverter in combination with our weld timer is the heart of every MATUSCHEK medium frequency welding system. In a master-slave configuration, which requires two SPATZ+ inverter, higher output currents are also possible. For example, for use in aluminium welding.

Upgrade ServoSPATZ+

In order to upgrade the SPATZ+ weld timer to the ServoSPATZ+ technology controller, only one (or two) SEC extension cards and one (or two) SPM power modules are required which are mounted in the switch cabinet next to the controller. With this upgrade it is possible to control up to two servo actuators.
