ER70S-6 is a common welding wire classification. "ER" stands for "Electrode Rod," "70" indicates a tensile strength of 70,000 psi, "S" means it's a solid wire, and "6" refers to the chemical composition, specifically higher levels of deoxidizers like silicon and manganese for better weld quality on slightly rusty or dirty steel.
