All good advice so far. I would recommend a little time on the training section of the Miller web site. I would also consider a name brand MIG to get going for parts service reliability etc. Make sure you get a package that can handle a backing gas as well as a flux core wire. Make sure your polarity is correct for whichever of those. 220 is more efficient and capable of heavier welding as well as lighter gauge. If you can swing it a plug for a spool gun is a nice feature if aluminum is in your future. Good luck with it, once you've learned some settings you'll really learn by doing. Push on lighter stuff, pull on heavier stuff!
