DCEN stands for direct Current Electrode Negative. It is one of the ways of arc welding. When a work piece is attached to positive terminal and electrode is attached to negative terminal, then this method is Direct Current Electrode Negative.

DCEP refers to Direct Current Electrode Positive. It is another way of arc welding. When a work piece is attached to negative terminal and electrode is attached to positive terminal, then this method is Direct Current Electrode Positive.
