An awful time you'll have, then. U groove rollers? 2 or 4 roll feed? (not single with idler anyway) Liner setup and/or capiliary tube? 3m euro torch so you can undo birdsnests? 200 amps and minimum 23 volts? Real volts and amps, not chinese ones. You'll need all of these things, and a bit of help/know-how to make it run nicely. If you buy the first welder you see that fits the budget, then you'll be lucky to run 20mm of weld without misfeeding.
