Dear Ganesh,
Constant current power sources are preferred in the process where the control is manual. e.g SMAW so that if at all there is variation in the arc length in welding it implies variation in the voltage but the current remain almost constant. But whereever machine operation is possible generally constant Voltage power sources are preferred

Hello friends
I had an doubt regarding the power source. Why DC-CC power source is not preferred in SAW process.
Due the voltage variations or any other specific reasons
kindly reply me if any one knows the answer
