Question

Quizplus · Accepted Answer

DCEP (Direct Current Electrode Positive) is commonly used in welding processes such as TIG and MIG. In DCEP, the workpiece is connected to the negative terminal and the electrode is connected to the positive terminal of the welding machine. As a result, approximately 2/3 of the arc heat is concentrated on the electrode and 1/3 of the heat is concentrated on the workpiece or plate. Therefore, the best choice is D).
