Final answer:

Shielded metal arc welding uses a direct current power source.

Step-by-step explanation:

Shielded metal arc welding (SMAW) uses a direct current (DC) power source. The power source is typically a DC generator or a rectifier that converts alternating current (AC) into direct current. The DC current is used to create an electrical arc between the electrode and the workpiece, which melts the metal and forms a weld.
