Aim of study is to reduce the breakdown of power source used for welding process and also increasing itsduty cycle. The main requirement of a power source is to deliver controllable current at a voltage according to thedemands of the welding process being used. Each welding process has distinct differences from one another, both in theform of process controls required to accomplish a given operating condition and the consequent demands on the powersource. Therefore, arc welding power sources are playing very important role in welding. The versatility of waveformcontrol is a major achievement of power source developers and manufacturers. To enable the exploitation of suchadvanced capability however, the personnel in charge of utilizing the sophisticated equipment must have sufficienttraining. We identify the problems like unstable arc generation with optimum arc length and also Power source breakdown during overnight and continuous production. As observed in SMAW process as current increases, heat generated,heat accumulated and rest time increases while duty cycle decreases. Parameters responsible for unstable arc length arestudied and solution for stable arc is obtained. Formula for desired duty cycle is obtained which can be controlled bysetting various parameters.
