Glassy melted low- manganese flux. Suitable for direct- and alternating current welding at high current up to ca 900 Ampere per wire. The flux causes slight increase of manganese and silicon in the weld, not changing Mn/Si ratio, which ensures high toughness properties of the weld metal and enables to weld plates of unlimited thickness.
