WebBoth direct current (DC) and alternating current (AC) are used for electric arc welding, each having its particular applications. For AC welding supply, transformers are … WebPolarity is simply a term to describe the whether the electrode is a cathode or anode. Quite simply it refers to whether the electrode is emitting (negative polarity) or receiving electrons (positive polarity). These terms are related to DC welders only. Welders that output AC current have no need to refer to polarity. ost inc

Web09. apr 2024. · In the case of a direct (DC) current, electrodes come in pairs, and are known as anodes and cathodes. For a battery, or other DC source, the cathode is defined as the electrode from which the current leaves, and the anode as the point where it returns.
