ER70S-6 MIG Premium Welding Wire, Carbon Steel, 0.045 in dia, 264 lb Drum

Features: 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
