Weldman Synergic Pvt. Ltd. Tala, Kolkata, West Bengal

WELDMAN series of Thyristorised Welding Rectifiers are fully electronically regulated transformer rectifier unit having constant current characteristic, suitable for manual metal arc welding and as a power source for TIG welding and Gouging.The machines have been designed to ensure good quality of welding even by a beginner. The use of technically best suited raw materials along with innovative design makes them very reliable and suited for continuous heavy duty operation. The unit is housed in a sturdy sheet metal casing, suitably ventilated, having four wheel, two of which are swiveling and are complete with a handle for easy movement. The machine is provided with lifting hooks for transportation by crane.Other optional accessories like remote control and power factor correction capacitor can also be provide at extra cost.

In INVERTER based Power Source,the input supply is applied to a diode bridge circuit where it is rectified and filtered to produce a pure DC voltage.Solid state switches then chop the DC to provide a high frequency,which is beyond audio range.The high frequency voltage is then applied to the primary of a transformer,the secondary of which is then rectified and filtered.The DC power so obtained is utilized for welding by transforming it to either Drooping or Flat characteristic. Because of the high frequency,the required magnetic components like transformer and choke become smaller in size resulting in lower losses,making the machine highly efficient.Reduction in size of magnetic components also reduces the weight of the machine and makes it compact.Also,due to high frequency,the response of the machine to the changed arc condition is very fast resulting in good quality welding with minimum spatters.
