TIG,MIG/MAG, WELDING TORCHES

	Inverter controlled welding rectifiers are manufactured using high frequency switching device called Insulated Gate Bipolar Transistor (IGBT) and Ferrite core transformer. Input main supply is converted into DC using diodes and is INVERTED into AC using IGBT and the output voltage is stepped down using the ferrite core transformer. Subsequent rectification & filtering provides almost pure DC output for welding applications. Power source is very compact & weighs only 10% compared to transductor/thyristor controlled machines. Efficiency and power factor for these machines are very high.
Input current for a given output in comparision to Thyristor/Transductor controlled machines, is only 50%. This amounts to tremendous savings. Weld quality is very good. Spatter level is negligible. Overall saving is quite substantial in comparision to Transdutor or Thyristor controlled machines, inverterised machines can be incorported with advance welding features. Most ideal machines for TIG, STICK (MMA) welding applications.
