Power Source


  • The possibility of adjusting the wire feed speed independently of other welding parameters
  • MF = 100% at T = 40 ° C at Max current means continuous operation of the machine
  • High energy efficiency (efficiency 96%)
  • Extreme speed (inverter frequency + control system clock cycle)
  • The possibility of increasing the current by connecting power modules up to 2000A
  • The protection class guarantees the safety of the device under severe operating conditions (IP34)
  • Free digital control of all welding parameters
  • Printed circuit boards in St. Petersburg

Extremely high response(inverter operation frequency and control system operation cycle)

Proprietary software

Duty cycle 100% at t=40°C at the maximal current means that the welding unit operates non-stop

High energy efficiency

Welding with modulated current with frequency up to 15000 Hz by independent control of currents L1 and L2 which, among other things, reduces sound pressure

Modular Architecture of power parts

Full Digital Control of all Welding Parameters

Option of increasing currents by parallel connecting power modules upto 2000A
