Other Details

We have an exclusive range of AC/DC Welding Rectifiers which is of superior quality and is now popular nationwide. We are also engaged in supplying air cooled dc welding rectifier keeping quality factor in mind. All these are available at affordable prices. Now we have carved a reputed name for ourselves in the market.

Following are the salable features of our product :

  • 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 ie stainless steel.


Process :

Our range of SR series of welding rectifiers are forced air cooled, silicon type. These 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. Our sets are also suitable for argon and are welded where DC is necessary and are supplied with built in high frequency suppressor. 600 SR welding rectifiers is suitable for gauging also.
