Characteristics:<\/strong><\/p>\n

LKE-NiCu-7 is a low hydrogen type covered electrode. Excellent weldability and stress corrosion resistance are obtained.<\/p>\n

Applications:<\/strong><\/p>\n

It is suitable for Monel 400, valves, pump and propeller of petrochemical plant.<\/p>\n

Notes on Usage:<\/strong><\/p>\n

1.Dry the electrode at 350-400\u2103oc for 30-60 minutes.
\n2.Use small amperage and keep the arc as short as possible.
\n3.Flat position welding is recommended<\/p>\n
