What alternate name is often given to Direct Current Electrode Positive (DCEP)?

Direct Current Electrode Positive (DCEP) is commonly referred to as forward polarity. This designation comes from the fact that during the welding process, the electrode (or the positive terminal) connects to the torch, which results in the workpiece being the negative terminal. This polarity configuration is crucial when considering the effects on the weld pool.

DCEP facilitates deeper penetration of the weld and contributes to a stable arc. The positive polarity helps in heating the tungsten or consumable electrode while simultaneously directing a significant portion of the current towards the workpiece, which enhances the quality of the arc and the weld bead.

Additionally, this type of polarity results in a cleaner weld, as the positive charge helps to repel impurities from the weld area. Understanding this concept is vital for selecting the appropriate welding setup for various applications, as it influences the overall welding characteristics and outcomes.

The term "reverse polarity" typically refers to Direct Current Electrode Negative (DCEN), where the electrode is negative, and most of the heat is generated at the workpiece. Other terms like "common polarity" or "stable polarity" do not accurately convey the principle of DCEP and might not be recognized in standard welding terminology.
