ER70S-4 MIG Welding Wire Carbon Steel MIG Wire
Specification:
ER70S-4 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-4 produces quality welds with rimmed steels, better welds on semi-killed
steels and excellent welds on killed steels. It 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.
Applications:
Automobile frames, earthmoving and farm equipment, sheet metal, ships and barges, railcars, trailers, ornamental iron, metal furniture, storage bins and general fabrications.
