Washington Alloy, TT 70S-3 02, Welding Wire, 0.035 in; 36 in, 60-235 A, AWS A5.18 ER70S-3

ER70S-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. This wire may be used for short-circuiting arc (dip-transfer), buried arc, as well as spray transfer arc processes. ER70S-3 produces quality welds with rimmed steels, better welds on semi-killedsteels and excellent welds on killed steels. It yields an almost slag-free deposit which does not require cleaning for many applications therebyproviding low plate preparation costs, good bead appearance and welder satisfaction.
