DSP with Chopper Technology

 

  • Digital electronic current control at high frequency (40 kHz) for more stable welding arc.
  • MOSA proprietary software controls all the welding parameters (with Chopper Technology) not only the current.
  • TIG welding "Contact-Start" easy to use.
  • Higher efficiency means more power (up to 14%) available for welding and
  • More auxiliary power available while welding.
  • No reactance needed to smooth welding output means:
  • Less weight,
  • Less voltage drop and
  • Less heat and heat related problems
  • Optional VRD (Voltage Reduction Device) for Australia.

Conventional analogic engine driven welders

 

  •  Traditional current control using normal rectifiers (SCR’s) results in ripple which causes spatter and an unstable arc.
  •  Only the current can be controlled and it is not possibile to adjust any other welding parameters.
  •  TIG welding requires HF box.
  •  Less welding power from the same source (engine).
  •  Less the auxiliary power available while welding.
  •  Reactance required to smooth the ripple and reduce spatter means
  •  More weight,
  •  Lower arc voltage and
  •  Generates unnecessary heat and current loss
  •  No VRD available from the factory
