E6010 electrodes require which polarity for welding operation?

Explanation:
Polarity in shielded metal arc welding changes where most of the heat goes and how the flux behaves. E6010 is a cellulose-coated electrode designed to produce a very hot, deep-penetrating arc. Using DC reverse polarity—electrode positive and work negative—puts more heat into the base metal, which yields deeper penetration and a solid root pass. The coating helps stabilize the arc and provides good slag control under this polarity, supporting the intended weld characteristics of this electrode. Other polarities, like AC or DC straight polarity, don’t deliver the same heat distribution and arc behavior for this electrode, so DC reverse polarity is the preferred and expected setting.
