Product Category : Rectifier

Technocrats Plasma Systems Pvt. Ltd. Manufactures Inverter Controlled Welding Rectifier. Technocrats Plasma Systems Pvt. Ltd. Is an ISO 9001:2000 certified company. Inverter Controlled Welding Rectifier is 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 and filtering provides almost pure DC output for welding applications. Power source is very compact & weighs only 10% compared to transductor or thyristor controlled machines. Inverter Controlled Welding Rectifier has a weld quality that is very good, and the spatter level is negligible. Inverter Controlled Welding Rectifiers can be incorporated with advance welding features using micro controllers or otherwise, incorporating pre-flow, post-flow, up-slope, down-slope, pulsing frequency, background current, peak current etc. Inverter Controlled Welding Rectifier is specially designed for cellulosic electrodes used in cross country pipeline applications.
