"EN" and "EP" amperage refer to electrode negative (EN) and electrode positive (EP) currents in welding processes, particularly in methods like Gas Tungsten Arc Welding (GTAW) or Shielded Metal Arc Welding (SMAW). EN, or direct current electrode negative (DCEN), focuses more heat on the workpiece, providing deeper penetration, whereas EP, or direct current electrode positive (DCEP), concentrates more heat on the electrode, which can aid in cleaning the workpiece surface but typically results in shallower penetration. The choice between EN and EP affects the weld characteristics and is selected based on the desired outcomes for the weld joint.
