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

Benefits in an overview:

  • High flexibility 

NIMAK submerged arc machines guarantee a high flexibility for band plating, electro slag welding, MIG/MAG automated welding and gouging thanks to reversible characteristics. 

  • Perfect quality 

We develop, design and produce welding machines for more than 50 years. Therefore, we exactly know what is important. The perfect welding quality is all times the key element of all our creative power. Our submerged arc machines reach their unchanging high and constant welding quality thanks to voltage compensation. 

  • Functioning connection 

Direct SPS connection is possible due to the interface and a isolated current / voltage measurement.

  • Customers choice 

All well-establishe bus modules like profinet, profibus or interbus are optionally selectable. 

  • Very solid desing 

Perfectly suitable for special production surroundings. 

Typical applications

The high performance procedure is suitable for multiple applications: 

  • Pipe constructions for wind power plants 
  • Pipelines 
  • Turbine constructions 
  • Shipbuilding 
  • Vehicle constructions 
  • Bridge constructions 
  • Steel constructions: Apparatus and container constructions, tank systems, hydraulic cylinders, pumps, fittings, steel beams and cranes
