Basic 55 welding electrodes E7016 - E 38 3 W 12 H10
Basic 55 is a double coated basic-rutile electrode for all welding positions, except vertical down position. This electrode is characterised by easy handling, a well controllable arc, excellent root penetration, easy slag removal and excellent metallurgical properties up to -30ºC. Typical applications include shipbuilding, general constructions, bridges, storage tanks as well as root pass and positional welding. Basic 55 is an all-current type (AC/DC).
