Submerged arc current sources

For demanding single- and multi-wire submerged arc welding

The DC and AC technic are characterized by the following: 

  • Duty Cycle 100% at 24 hours / 7 days operation 
  • Design stationary or mobile 
  • Can be lifted by crane and moved by fork lift 
  • Performance level: 800 / 1000 / 1250 / 1500 / 2000 A
  • Standardized nominal / real value 
  • Isolated current- and voltage recording 
  • Characteristics switchable CC/CP/CM (Stellbetrieb)
  • Secondary connection pluggable or fixed connection 
  • Welding source to be changed without readjustment
