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 supplies come with the current fed converter technology:
- a digital regulation
- our patented arc current limitation
- a configurable arc management.
The arc current limitation restricts the output current in case of an arc. Therefore the process runs more smoothly and stable. The WELTEC devices are water-/oil-cooled and can be featured with more auxiliary equipment such as heat or Wehnelt supply. They are available with output voltages of 60, 120 or 150 kV and with output ratings of 7.5, 10 and 15 kW.
