WELTEC E-Beam welding Power-Supply

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.

Standard             
•  Analogue and digital I/O-interface
•  RS232-interface
•  Digital regulation (U, I, P)
•  Configurable Arc-management 
  (up to four parameter sets store able)
•  Bootloader for service 

Description
• Device are in different output voltage available
• Remote control (RS232 <-> Hyper-Terminal) possible

Options 
• Integration of the necessary auxiliary supplies
• Profibus, Canbus or EtherCat
