Thyristorised Welding Rectifier

We supply supreme quality thyristorised welding rectifier which cannot be availed anywhere else. We also supply fully thyristorised welding rectifier which is of exclusive quality as well. Our welding rectifiers are available at quite reasonable prices. We have also gained the position of one of the reliable welding rectifier suppliers in India. Process Weld Aid India SR Series, fully thyristorised MMA welding rectifier is built using advanced, solid state technology and is designed to meet the stringent demands of high quality radiographic welding in todays fabricating industries including Nuclear Power Plants, Chemical Process Plants, Deference, Steel Plants, Deference, Steel Plants, Thermal Power Plants, mining and Structural Fabrications, among others. FEATURES

  • True, vertical welding current characteristics with higher open circuit voltage
  • Immunity from AC input vottage fluctuation, with built-in overload and thermal cut-out protections.
  • Hot start facilities for easy arc striking
  • Effective prevention of electrode freezing. Single range current control with remote control facilities.
  • Low input KCA rating
  • Six-phase ripple free DC output gives excellent welding quality.
  • Ideal for precise TIG welding with necessary accessories.

AC/DC Welding Rectifier

Our AC/DC welding rectifier is of exclusive quality and is highly famous. We also supply air cooled Dc welding rectifier which is also of premium quality. Our DC welding rectifiers can also be availed at quite affordable prices. We have positioned ourselves as one of the prominent welding rectifier manufacturers in India. FEATURES

  • Piper in all positions.
  • Non ferrous metals.
  • Low alloy, corrosion, heat and creep.
  • Mild steel and low alloy steel at site where welds of high radiographic standards are required.
  • Mild steel and low alloy steel in lighter gauge resisting steel i.e. stainless steel.

PROCESS Weld Aid India Sr Series, of welding rectifiers are forced air cooled, silicon type and are designed to provide a DC welding current where 3 phase, 50 HZ AC mains power is available at voltage ranging from 380 to 440 Weld Aid India sets are also suitable for Argon are welding where DC is necessary and are supplied with built in high frequency suppressor. 600 SR welding rectifiers is suitable for gauging also.
