What is Constant Current Power Source in Welding about?

This document discusses constant current power sources, which are preferred for manual welding like MMA and TIG welding. Constant current power sources maintain an essentially constant current even as the arc voltage varies within a normal range during welding. The welder sets the desired current and controls arc length, which determines arc voltage along the drooping voltage-current curves of the power source. This allows the welder to maintain control of the fusion process despite small variations in arc
