Heavy coated basic type electrode for welding fine grained structural steels which have yield strength up to 690N/mm². Suitable for welding high strength steels used in fabrication of cranes, earthmoving and similar heavy construction equipments. Weld deposit is of extremely high metallurgical purity and very low hydrogen content. Electrode features a stable and concentrated arc. Especially 2,50 mm and 3,25 mm diameter well suited for easy positional welding. Welds are of X-ray quality. Producing tough and crack-free welded joints. If normalizing is required after welding, EM 176 should be used.
