Power Sources

A welding power supply provides an electric current for welding. A constant current (CC) machine varies output voltage to maintain a steady current, while a constant voltage (CV) machine fluctuates output current to maintain a set voltage. Shielded metal arc welding (SMAW) and gas tungsten arc welding (GTAW) use a CC source, and gas metal arc welding (GMAW) and flux-cored arc welding (FCAW) typically use CV sources, though constant current is also possible with a voltage sensing wire feeder.
