Product description

Basic coated electrode, producing tough and crack-free welded joints. Suitable for welding of high strength and low alloyed steels and fine grained structural steels. Weld deposit is of extremely high metallurgical purity and has a very low hydrogen content. Owing to it's double coating, electrode features a stable and concentrated arc, making especially up to 3,25 mm, are well-suited for positional welding. Welds are of X-ray quality.
