Shielded Metal Arc Welding (SMAW), also known as stick welding, primarily requires a **constant current** power source. This is because a constant current source helps maintain a stable arc length even as the electrode is consumed or while moving the electrode in and out of the workpiece.
While other power sources like constant voltage may be used in other welding processes, SMAW is best suited for a constant current setup. The power source also usually features a suitable open circuit voltage to initiate the arc when starting the weld.
