INTERNATIONAL CLASSIFICATIONS

AWS/ASME A 5.15 E Ni-CI

DIN 8573: E Ni BG 11

ISO 1071: E Ni

NFA 81-342: E Ni BG 11

FEATURES & APPLICATIONS

Very soft machinable welds on all weldable cast irons. Especially suited for welding in deep recesses or close quarters due to the non-conductive flux coating.

• Soft very machinable high nickel cast iron electrode featuring a totally non-conductive flux coating.
• Flux coating does not side arc even after being heated.
• Unusually strong arc drive penetrates oil and grease easily.
• Excellent for vertical up welding.
• Can be ordered in a red/brown flux color as product Code 1840.
• Also available in TIG form as product code 6004.
