DCEN stands for Direct Current Electrode Negative.

• A. Direct Current Positive
• B. Direct Current Neutral
• C. Direct Current Electrode Negative
• D. Direct Current Electrical Negative

Answer: (C)

Direct Current Electrode Negative is the standard term for DCEN. Here, the electrode is connected to the negative terminal, so current flows from the electrode into the workpiece. The acronym directly matches the words: Direct Current Electrode Negative. This polarity is often used when you want heat to be applied more to the base metal and to reduce heat and wear on the electrode, affecting penetration and electrode consumption. It contrasts with Direct Current Electrode Positive, where the electrode is positive and more heat goes into the electrode.
