Which statement is true about current type for overhead welding on mild steel?

Direct current is used for overhead MIG welding of mild steel because it provides a stable arc and predictable puddle control in the overhead position. Using DC concentrates heat into the workpiece, giving consistent penetration and bead shape, while helping manage spatter and arc stability. Alternating current is not typically used for this steel welding scenario, and micro-surge current isn’t a standard setting for overhead GMAW. So, DC is the typical current type.
