which polarity places 2/3 of the heat of the arc onto the base metal and 1/3 on the electrode?\ndcep\ndcen\nac\ndcnp

Answer

Brief Explanations:

In welding, DCEP (Direct Current Electrode Positive) polarity results in approximately two - thirds of the arc heat being directed to the base metal and one - third to the electrode. This is due to the electrical and thermal characteristics of the welding arc in this polarity configuration. DCEN (Direct Current Electrode Negative) has more heat on the electrode. AC (Alternating Current) polarity alternates the heat distribution. DCNP is not a standard welding polarity term in this context.

Answer:

DCEP
