ER70S6 is a mild steel welding wire that contains high levels of manganese and silicon which produces high quality welds when used on dirty, oily, or rusty steelThe high silicon content increases the fluidity of the weld pool, creating a smoother bead appearance resulting in minimal post-weld grindingS-6 wire is engineered to provide porosity-free, x-ray quality welds at the highest tensile strength of all the plain carbon steel wiresThis product requires a shielding gas of CO2 and/or CO2 mixWires conform to AWS 5.18 and CSA 48.4Testing and Approvals:Conforms to AWS5, 18; CSA 48.5
