AC vs DC welding.
I'm not contesting whether DC is better. Consensus is "yes"
But what about the physics of _WHY_ it is better?
Theory: when a droplet of steel on the electrode is charged opposite of the workpiece, it is drawn toward the workpiece. BUT in AC, there are moments when the charge drops to zero and reverses. At that time, might the droplets of steel, for just a moment, be electrostatically drawn back toward the electrode?
