Question

Difference between ac arc welding and dc arc welding

Answer 1

Answer:

Explanation:

DC Welding. ... It produces a smoother welding output compared to AC. It creates a more stable arc, easier welding and less spatter. You can also either use DC negative for faster deposition rates when welding thin sheet metal or use DC positive for more penetration into the steel.

Answer 2

The main difference between the two is with the recommended welding polarity. E6010 electrodes are intended for direct current (DC) only. While E6011 electrodes can be used on alternating current (AC), as well as DC. ... The latter helps keep the arc ignited as the welding output alternates from positive to negative.
