WELTEC

The power supplies of the WELTEC series are specially developed for e-beam welding, e-beam melting, industrial x-ray applications and sterilization applications. The High voltage power supply comes within the modern CFC (Current Fed Converter) technology, a digital regulation, our patented Arc current limitation as well as a configurable Arc-management. The Arc current limitation limits the output current in case of an Arc and therefore the process runs more smoothly and stable. They are water- / oil cooled and it is possible to integrate the necessary auxiliary supply such as heat or wehnelt supply. They are available with output voltages of 60kV, 120kV up to 150kV and with output ratings of 7.5kW, 10kW and 15KW.
