What is meant by reverse polarity?

• A. Direct Current Electrode Positive
• B. Direct Current Electrode Negative
• C. Alternating current
• D. No polarity

Answer: (A)

In arc welding, polarity tells you which electrode terminal is positive or negative. Reverse polarity means the electrode is connected to the positive terminal (Direct Current Electrode Positive). The current flows from the workpiece (negative) toward the electrode (positive) across the arc. This setup changes where heat is concentrated and how the electrode and its coating behave, often improving arc stability and slag handling for many coated electrodes. In short, reverse polarity = electrode positive.
