Gotta love it when the wrong thing shows up, then its time for (lets make ah deal).
I started welding with a HF flux core machine and a 235 ac/dc hobart stick machine. Long story short, the HF is long gone and I now have a miller 211 mig. I never really even tried the thin stuff with the stick until this last project, I always just figured it was for the heavy stuff. I changed things up from the normal 7018 dc and ran some 6013 ac. WOW is all I can say. Its so much nicer to drag a stinger and lead with ya over the whole mig machine, especially working on my trailer. Maybe one day I will have a grown up stick welder with a few more options.
On the tires, since they were for load bearing use, are they highway legal or for off road use only?
