Welding Current Types DCEN, DCEP, AC

There are three different types of current used for welding are alternating current (AC), direct-current electrode negative (DCEN), and direct current electrode positive (DCEP). The terms DCEN and┬áDCEP have replaced the former terms direct-current straight polarity (DCSP) and direct-current reverse polarity (DCRP). In other words, DCEN and DCSP are the same currents, and DCEP and DCRP are the same currents. Some electrodes can be used with only one type of current. Others can be used with two or more types of current. Each welding current has a different effect on the weld. DCEN – Use for GTAW, SMAW- Root or … Continue reading Welding Current Types DCEN, DCEP, AC
