Characteristics
A high quality specially formulated rutile coated all purposes mild steel electrode, especially designed for vertical and overhead positions, using AC or DC power sources. Weld appearance is neat and smooth. Other features include quiet arc and easy slag detachability even in deep grooves. Root runs have a neat profile and smooth appearance with complete freedom from undercut. Spatter level is exceptionally low.
Applications
The electrode is suitable for general construction, structure and framework, sheet metal work, ship building, bodies and under frames of railway carriages, wagons, storage tank etc.
