This makes an erratic flow for SMAW, producing more spatter and a more unstable current. I used AC for welding 6011 for a couple of years. The welds were OK, but give me DC anytime. 3. Direct current electrode positive (DCEP) is what we used to call reverse polarity. Direct current electrode negative (DCEN) is what we used to call straight polarity. I suspect the same person who changed the word library to the learning resource center got a hold of these terms. In DCEP the electricity flows into the tip of the welding rod and concentrates about two-thirds of the heat, which gives good penetration.
