In reverse polarity, what is the designation of the red rod?

In reverse polarity, the designation of the red rod refers to the type of current flow used in the welding process. In SMAW, the electrode is connected to the positive terminal of the welding power supply when operating under reverse polarity, which means that the electrode becomes the anode in this configuration. This is significant because it influences the characteristics of the arc and the way heat is generated during the welding process.

In reverse polarity, the red rod typically indicates a specific type of electrode design optimized for the positive terminal connection, which promotes deeper penetration and a more stable arc. It is important to recognize that the classification of the electrode as "reversed" indicates its role in polarity configuration, rather than relating to its neutral or grounded status.

Understanding this designation supports welders in selecting the appropriate electrodes for specific applications, ensuring they achieve the desired weld quality and properties based on the heat and penetration characteristics provided by the reverse polarity configuration.
