Alloy ER 70S-3 is a silicon and manganese deoxidized wire used for mild and low alloy steel general purpose fabrication. A well balanced silicon and manganese content permits its use with CO2 , Argon-Oxygen mixtures, or mixtures of the two. The alloy ER70S-3 produces quality welds with rimmed steels, better welds on semi-deoxidized steels and excellent welds on fully deoxidized steels. This wire also yields an almost slag free deposit, which does not require cleaning for many applications thereby providing low plate preparation costs, good bead appearance and welder satisfaction. Some typical applications include earthmoving and farm equipment, automobile frames, sheet metal, ships and barges, railcars, trailers, storage bins and general fabrication.
