Copper Bridge E6011 Stick Electrode
DESCRIPTION
Copper Bridge E6011 is a cellulosic-coated electrode for carbon steel that can be used with AC or DC+. It supports allposition welding with high welding efficiency and smooth weld appearance. Arc length should be controlled appropriately, weave width should not be too wide, and it is not intended for multi-layer or cover welding.
