What is another name for direct current electrode positive?

Direct current electrode positive (DCEP) is primarily characterized by the direction of the current flow in MIG welding. In this setup, the workpiece acts as the positive terminal while the electrode behaves as the negative terminal. This arrangement is significant because it enhances the heat generation at the workpiece, allowing for deeper penetration and effective fusion of the base metal.

The term "reverse polarity" accurately describes this configuration since it outlines how the electrical current flows. When using DCEP, a larger amount of heat is generated at the workpiece as opposed to the electrode, which is particularly beneficial when welding thicker materials.

Other options do not accurately represent the same concept or function. For example, DCEN (direct current electrode negative) refers to the opposite polarity where the electrode is positive and the workpiece is negative, causing less heat at the workpiece. AC polarity involves alternating current, which does not have the same stable heat characteristics as DCEP, making it unsuitable for certain types of welding needs. Finally, DC reverse current is not a standard term used in welding terminology and can lead to confusion regarding its meaning and application.
