This 70S-6 Bare is an non-copper coated carbon steel that contains high-levels of manganese and silicon for stronger deoxidizing power while having excellent welding results at optimal control at high welding speeds and amperage found in robotic or automation. Found in stuctural carbon steel Pipeline/fitting, Automotive, Pressure vessel, and general fabrication of mild steels where poor fit-up, rust, and oils may be present. 70S-6B yields excellent low fume, low spatter, reduced copper fumes, and less heat buildup in excess long liners
