Magnetic Rectifiers

Description

Welding Power sources designed for dc output. Used for Stick (MMAW) welding and TIG (GTAW) welding.

Applications

  • (MMAW) General Fabrication, Repair, Maintenance, Structural Steelwork, Process Plant, Shipbuilding etc.
  • (GTAW) Suitable for use in mechanized and automated equipment, Automobile, Aerospace, Power generation, Chemical Plant Equipment, Nuclear Plants, Food processing machinery etc.

Features

  • Optimised design of transductor ensures smooth & steady arc with minimum spatter.
  • Full wave silicon rectifier with excellent welding characteristics.
  • High open circuit voltage to accommodate easy arc striking of wide variety of welding electrode.
  • High quality CRGO laminations ensure very low idle power consumption.
  • Fully copper wound with near perfect design ensures low energy consumption with trouble free service life.
  • Robust design with powder coated chassis ensures long life in site conditions also.
  • Easily adaptable for TIG or Plasma application with necessary Add-Ons.
