Hi all. I'm sure this has been asked somewhere, but after a quick search, I didn't find anything. I'm in the market for a used Tig welder. I would like to stay under $2k. (Ideally including bottle and accessories).What are your opinions on the best bang for that amount of buck. I would be welding mostly .120 wall or thinner tube, and occasionally maybe 3/8" thick plate at the most. Any suggestions on specific models and why would be a great help.
