Properties

Remarkable crack resistant weld metal in combination with very low hydrogen content. Therefore, suitable for the economic processing of high-strength and low temperature fine-grained structural steels. Exelent welding properties in short and spray arc. Excelent gab bridging for root welds. High deposition rate and no intermediate cleaning required with very low spatter loss. Weld metal is heat treatable.
