What is the difference between DCEN and DCEP in welding?

Evaluate responses using AI:

OFF

Answer explanation

DCEN stands for Direct Current Electrode Negative, where the electrode is negative and the workpiece is positive. DCEP stands for Direct Current Electrode Positive, where the electrode is positive and the workpiece is negative.

Why is DCEP called reverse polarity?

Evaluate responses using AI:

OFF

Answer explanation

DCEP is called reverse polarity because the electrode connected to the positive terminal is the workpiece, while the electrode connected to the negative terminal is the consumable electrode.
