jack..
Miller 215 will handle it. Any stick welder (shielded metal arc welding SMAC/stick) tolerates rust way better than wire feed (mig). Flux core welders generally don't have a shielding gas like argon. I would steer away from anything that is a flux core wire feed welder and quite often they are 110v vs 220v. Mig essentially needs cleaned metal to be welded and a SMAC/stick welder can generally weld just about any condition of metal. With that being said, I clean all the metal to be welded. SMAC is very different than MIG but in my humble opinion you will be on a SMAC welder a long time to learn up welds and down welds. MIG is easier and more forgiving but also a pain in the butt when if comes to clean metal, the gas, the spool, the tips, the tools. SMAC grab a rod and start welding.
fyi.. splatter is not good welding.. you want it to sound like bacon frying.. I am not an expert welder, but I get the job done and it holds! I can do both, but 220V, MIG with argon, it is nice and it makes amauters like me look like a PRO! I am very confident that Plottin' Booners on a stick is like watching an artist paint
