What is another term for Electrode Negative in welding?

The term "Electrode Negative" in welding refers to a situation where the electrode is connected to the negative terminal of the power source. This configuration leads to a specific current flow during the welding process. When the electrode is negative, a greater amount of heat is generated at the workpiece rather than at the electrode itself. This is beneficial for penetrating thicker materials and achieving a more focused arc.

The correct answer relates to the concept of "Straight Polarity," which is specifically used to describe the arrangement of the electrical connections in this context. Straight Polarity is synonymous with Electrode Negative, highlighting that the negative electrode connection leads to the desired heat distribution.

In contrast, other terms listed do not fit this definition. Reverse Polarity refers to the opposite configuration (where the electrode is positive), AC Welding uses alternating current rather than a direct current system, and Direct Current Electrode Positive indicates the flow of current where the electrode is connected to the positive terminal, resulting in a different heating pattern. Understanding these distinctions is crucial for applying the correct welding techniques based on the current flow and desired outcomes in metal joining.
