I'm trying to weld some braces (mild steel) to the back side of a snow plow cutting edge (hardened steel). I'd like to mig weld them with my mild steel wire. I've been told that the best bet would be using a 7018 electrode and preheating the steel. Do you guys think I'll have any luck with my mig machine, or should I just go with the stick electrode for best outcome? Thanks for any tips, Nick.
