When using reverse polarity, where is about two-thirds of the heat located?

Explanation:
With reverse polarity, the electrode is positive and the workpiece is negative, so the arc heat concentrates in the base metal. About two-thirds of the heat goes into the base metal and weld pool, while the electrode absorbs about one-third. This causes deeper penetration into the base metal and a larger heated zone in the workpiece, which is why reverse polarity is chosen when more heat into the metal is needed.
