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.

WELDMAN Air Or Oil cooled AC welding machines are the result of long experience the designers of WELDMAN SYNERGIC Pvt Ltd have on these equipment. The latest design techniques and the choice of right and best quality raw materials make them ideally suitable for Manual Metal Arc welding and also as a power source for GTAW (TIG) welding. The WELDMAN AC welding Machines are manufactured as per BIS or IPSS depending upon the client’s requirement. For ship building industries these can be supplied to suit their specific requirement of open circuit voltage. The WELDMAN Welding Machines are designed keeping in mind the expectation of the user. The machines are light in weight, compact in size, reliable in operation and extremely rugged for continuous heavy duty welding for the size of the electrode as detailed in the technical specification. Some of the optional features that can be add are Oil Cooled Design Double or Multiple Operator Single or Dual OCV Can be supplied with Power Saving Devise. The machine can be as per BIS or IPSS
