ANR2871 Features: * A 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 * Requires a shielding gas of CO2 and/or C02 mix; conforms to AWS 5.18 and CSA 48.4 * Mild steel material * 85,000 psi tensile strength * Available in 12 lb spool Construction: * S-6 wire is engineered to provide porosity-free, x-ray quality welds at the highest tensile strength of all the plain carbon steel wires
