I think you need a 220v mig. I have a 120 v mig and the duty cycle shuts it down and it needs a 1/2 hour time tool cool.
The best bang-per-buck IMO is a refurbished Lincoln 125 or 140. For $550 you can get a complete 140 setup and ready to go for flux-core or gas, and it comes with a cart. You can find ones without the cart for cheaper.
Even though they're refurbished they still come with a three year warranty and any part that is even remotely worn is replaced.
I've never had an issue with hitting the duty cycle on max power with my 125 and flux core wire. It has an automatic temperature shutdown, but I've never hit it.
I'm amazed at how many people aren't reading the OP's post thoroughly enough to see that he already has most of the bases covered and just wants a portable 110V mig for simple small jobs. I think you're right on track looking at tractor supply. I have the Hobart Handler 140 that I purchased at Tractor Supply. Occasionally they go on sale for just under $500 and I think they're a solid buy. I'm very happy with mine and it seems to produce a nice solid, stable arc (however I use mine with gas) The nice part is that it comes with the regulator in case you ever want to use it with solid wire for some reason but it would work well with flux core for small and simple fabrication jobs out of the box too. It seems to be built better than the box store welders too with metal drive parts for the wire etc.
Don't waste your money on a 120V rig. Get dual voltage and make sure you can add gas.
I never have welded but I am wanting to learn. So the Hobart 140 is the best all around unit? Any others? Not trying to hi jack just wanting to learn.
