- 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 AWS A5.18:05; CSA W48:14 - WARNING: Cancer and Reproductive Harm - www.P65Warnings.ca.gov
