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.
