Reverse polarity for DC welding is called DCEP. Electrode is positive, work piece is negative. Electrons flow from work piece to electrode. This makes sense for deeper penetration - as the electrons in the work piece are more energetic prior to jumping to the electrode. | Reverse polarity for DC welding is called DCEP (DC Electrode Positive).
