ER70S-6 MIG Premium Welding Wire, Carbon Steel, 0.035 in dia, 616 lb Drum

Mild steel welding wire that contains high levels of manganese and silicon which produces high quality welds when used on dirty, oily or rusty steel. The high silicon content increases the fluidity of the weld pool, creating a smoother bead appearance resulting in minimal post-weld grinding. Engineered to provide porosity-free, x-ray quality welds at the highest tensile strength of all the plain carbon steel wires. Requires a shielding gas of CO2 and/or CO2 mix.
