Technical FAQs 4

What is a medium frequency inverter?

Medium-frequency inverters cover a wide range of applications. We offer a frequency band from 3 to 40 kHz in which the full power of the inverter can be used. It can be set up as a parallel or series resonant circuit. Highly flexible design simplifies integration into your production process.

What is a 1 000 Hz MF inverter?

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.

What is a medium frequency inverter welder?

Medium (till 1000Hz) Frequency Inverter Welders use millisecond pulse width modulation (switching) technology with closed-loop feedback to control the weld energy in sub-millisecond increments. Three phase input current is full wave rectified to DC and switched at 1kHz to produce an AC current at the primary of the welding transformer.

What is MF transformer?

The weight and size of the MF transformer is only 1/3 of the AC type transformer. Suitable for robot welding system. Be able to weld material like aluminum, galvanized steel, etc. with good welding performance. Especially suitable for three-layer plate welding, ultrathin material welding and precision welding.
