Basic electrode for non-alloy and low alloy steels, wide range of applications. Welding in all positions except drop welds. High resistance to wetting minimizes the risk of cracking. Weld metal exhibits excellent mechanical and physical properties. Excellent for root welds, for large section welds. Working temperature from -60°C to +450°C.For high quality welded joints on all types of steel structures, welding of railroad superstructures, steel and bridge structures, car bodies, trailers, tanks, steel castings, ship steels, low purity and high carbon steels. For mat. 1.0035, 1.0060, 1.0461, 1.0545, 1.0462,1.0565, 1.8836, 1.0345, 1.0425, 1.0481, 1.0473, 1.0308, 1.0581, 1.0307, 1.0499, 1.0484, 1.8972, 1.0441, 1.0476, 1.0513, 1.0585, 1.0420, 1.0552
