In DCEN, which polarity is associated with the electrode?

• A. The workpiece is positive.
• B. The electrode is negative.
• C. The workpiece is negative.
• D. The electrode is positive.

Answer: (B)

In DCEN, the electrode is connected to the negative terminal, so the electrode is the negative pole. Conventional current flows from the positive workpiece toward the negative electrode through the arc, while electrons move from the electrode to the workpiece. This polarity is chosen because it affects arc behavior and wear on the electrode, and is commonly used for many SMAW setups on steel.
