Arc welding is an extremely important and necessary industrial and construction process. This work aims at reduction in energy consumption of idling welding transformer and control of welding power and quality by employing PWM technique also real time monitoring and control of welding transformer parameters using MATLAB is desired. Welding is a noncontinuous process and employed in mechanical and civil construction process, the idling time of welding transformer is relatively high and thusdoi:10.22214/ijraset.2019.8086 fatcat:r3o5yl4p5fa2tpqrdhxdxaffgq
