Next I want to reverse the polarity of these two wires by setting another digital pin high... so the two states would be: Wire 1 = 5v. Wire 2 = 0v. Digital control pin = low. Wire 1 = 0v. Wire 2 = 5v. Digital control pin = high. Any pointers greatly appreciated. Docedison September 15, 2012, 9:28pm 2.As DC can only flow in one direction, it breaks into two polarity options: DC electrode positive (DCEP), also called reversed polarity. DC electrode negative (DCEN), also called straight polarity. More on these will come later. Most arc welding works best with DC because it provides a more stable arc with less spatter.Wall sockets that have reversed polarity are considered an electrical shock hazard, which is why they're noted on pre-purchase house inspections.
