Medium coated and Ni (nickel) alloyed cellulosic type electrode, suitable for welding high strength steels, micro-alloyed and low alloyed steels and pipes. Due to its high penetration, it is suitable for root pass and fill passes in the vertical down direction. Well-suited for welding high strength unalloyed and low alloy steels in shipbuilding, storage vessels, boilers, pipe-line constructions and assembly works. DCEN (-) is ideal in root passes and DCEP (+) is recommended for fill and cap passes in vertical down position.
