Truly the first indigenous moisture resistant, hydrogen controlled, vacuum packed, basic coated electrode which is welder friendly and is recommended forWelding of mild and medium carbon steel, high strength steel, cast steel and problematic steels. The electrode is vacuum packed and hence does not require expensive redrying at 250°C for 2 hours or a higher temperature. The weld metal is clean and has lowest level of impurities thus having unique properties of resistance to ageing.
All maintence applications including welding of all types of carbon-manganese steels, high tensile, heavy structures, plants and subject to static or dynamic loading. Can be used as a buffer layer before hard facing.
