Rated Input Power(KVA)50 Hz AC available
VIRDI 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 a voltage ranging from 380 to 440. Arc welding is one of several fusion processes for joining metals.

By applying intense heat, metal at the joint between two parts is melted and caused to intermix - directly, or more commonly, with an intermediate molten filler metal.

VIRDI series of welding rectifiers are suitable for manual arc welding particularly for the welding of:

Technical Details:
  • Pipes in all positions.
  • Non-ferrous metals.
  • Low alloy, corrosion, heat and creep.
  • Mild steel and low alloy steel at the site where welds of high radiographic standards are required.
  • Mild steel and low alloy steel is lighter gauge resisting steel i.e. stainless steel.
VIRDI sets are also suitable for argon arc welding where DC is necessary and are supplied with a built-in high-frequency suppressor.600 FC welding rectifier is suitable for arc gouging also.

PhaseSingle Phase, Two Phase, Three Phase
TechnologyInverter Based, Rectifier Based, IGBT Based
In arc welding, the intense heat needed to melt metal is produced by an electric arc. The arc is formed between the actual work and an electrode (stick or wire) that is manually or mechanically guided along the joint. The electrode can either be a rod with the purpose of simply carrying the current between the tip and the work. Or, it may be a specially prepared rod or wire that not only conducts the current but also melts and supplies filler metal to the joint. Most welding in the manufacture of steel products uses the second type of electrode.


Basic Welding Circuit:

The basic arc-welding circuit is illustrated in Fig. 1. An AC or DC power source, fitted with whatever controls may be needed, is connected by a working cable to the work piece and by a "hot" cable to an electrode holder of some type, which makes an electrical contact with the welding electrode.

An arc is created across the gap when the energized circuit and the electrode tip touches the work piece and is withdrawn, yet still with in close contact.

The arc produces a temperature of about 6500ºF at the tip. This heat melts both the base metal and the electrode, producing a pool of molten metal sometimes called a "crater." The crater solidifies behind the electrode as it is moved along the joint. The result is a fusion bond.

Arc Shielding:
However, joining metals requires more than moving an electrode along a joint. Metals at high temperatures tend to react chemically with elements in the air - oxygen, and nitrogen. When metal in the molten pool comes into contact with air, oxides and nitrides form which destroy the strength and toughness of the weld joint. Therefore, many arc-welding processes provide some means of covering the arc and the molten pool with a protective shield of gas, vapor, or slag. This is called arc shielding. This shielding prevents or minimizes contact of the molten metal with air. Shielding also may improve the weld. An example is a granular flux, which actually adds deoxidizes to the weld.

Figure 2 illustrates the shielding of the welding arc and molten pool with a Stick electrode. The extruded covering on the filler metal rod provides a shielding gas at the point of contact while the slag protects the fresh weld from the air.

The arc itself is a very complex phenomenon. In-depth understanding of the physics of the arc is of little value to the welder, but some knowledge of its general characteristics can be useful.

Nature of the Arc:

An arc is an electric current flowing between two electrodes through an ionized column of gas. A negatively charged cathode and a positively charged anode create the intense heat of the welding arc. Negative and positive ions are bounced off of each other in the plasma column at an accelerated rate.
