AC or DC—What’s the Difference?
Polarity describes which way the electricity is flowing. With direct current (usually called DC), the polarity of the electric current always flows one way. The normal flow is electrode negative, which means the electricity flows from the welder, through the electrode, to the workpiece, and back to the welder. Reverse polarity turns that around and drives the current from the welder through the workpiece to the electrode.
Direct current is favored for TIG welding most metals because it penetrates deeply. Welding aluminum is one of the only times that alternating current is preferred.
Alternating current, or AC, flips the polarity between standard and reverse quickly, from sixty to one hundred twenty times each second. Aluminum is usually TIG welded with alternating current. The quick polarity flips have a sandblasting effect that breaks up the surface oxides to produce a clean weld. The drawbacks to AC welding are that the weld doesn’t penetrate deeply and that it leaves a large bead on the surface.
