Question

During a steady gas metal arc welding with direct current electrode positive polarity, the welding current

Answer 1

Explanation:

Welding currents with electrode-positive (reverse) polarity result in deeper penetration, while electrode-negative (straight) polarity has the benefit of faster melt-off and faster deposition rate. Different shielding gases may further affect the weld as well.
