Copper Bridge E6010 Stick Electrode
DESCRIPTION
Copper Bridge E6010 is a cellulosic-coated stick electrode for carbon steel. It uses DC reverse connection and is suited to all-position welding of pipeline circumferential seams in the field, especially verticaldown root passes where one-side welding and two-side formation are required.
