Product Description

DC Welding Rectifier

This DC Welding Rectifier is used for removal of the spatter generation and stable arc with the regular droplet transfer.  DC welding rectifier is very useful for thin sheet welding and is able to produce wave showing welding. We manufacture this Rectifier using quality materials and are exported at reasonable price. DC Welding Rectifier is widely applicable in many fabrication industries for various welding and rectifying applications.  This DC Welding Rectifier is perfect for manual metal arc welding. They are also widely used to detect amplitude modulated signals.

Technical Specification :

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

Others Details

VIRDI chain of DC welding rectifiers are mandatory air-cooled, silicon kind and are fabricated to offer a DC Welding current where 3 Phase, 50 Hz AC mains power is accessible at voltage ranging from 380-440 volts. One of numerous fusion processes for joining metals is called as Arc welding. By providing severe heat, metal at the joint amid two parts is softened and is made to intermix directly or usually with a midway melted filler metal. When the cooling and solidification happens, a metallurgical bond is formed. Since the amalgamation is an intermixture of metals, the finishing welded part most likely has similar strong-point qualities as the metal of the parts. This is in quick disparity to non-fusion processes of fusion i.e. soldering, brazing etc. in which the automatic and material properties of the base substances cannot be reproduced at the joint.

VIRDI series of welding rectifiers are appropriate for manual arc welding predominantly for the welding of following products.

VIRDI sets are also appropriate for argon curve soldering where DC is essential and are supplied with built-in elevated frequency suppressor. In addition, 600 FC soldering rectifier is appropriate for arc gouging.

VIRDI succession of welding Rectifier is enforced air-cooled in silicon type. Amalgamation of well-fabricated rectifier & transduction unit gives even and stable arc with bare minimum sprinkling & outstanding weld blob. It gives ultimate DC power source for Manual Metal Arc and Tungsten Inert Gas (TIG) soldering..
