Application\/properties:<\/strong><\/p>\n\n\n\n

Basic electrode that uses nano technology in a humid environment with 80% humidity, the electrode coating is resistant to moisture absorption for 9 hours. This electrode is suitable for producing crack-free and tough welded joints. Weld metal is extremely metallurgical pure having very low hydrogen content. The electrode has a stable and concentrated arc, thus being well-suited or positional welding. Welds are of X-ray quality.<\/p>\n\n\n\n
