Tig welder for a beginner

You can find a lot of used TIG machines out there, stick with red or blue. (Lincoln or Miller) you likely do not need water cooled, entry level machines will run around 2k new. With TIG it is all about the prep. And yes it takes a bit of practice. I have earned a living running TIG torch since 80s and I am still learning! Aluminum and Magnesium take a bit more finess but in the end it is not as bad as it seems.

^^^THIS^^^ and GO BIG. And BE CAREFUL it is NOT 3 phase powered (unless your shop has 3 phase service, obviously)

You can routinely find Lincoln Miller 250A and larger machines around here for 400up. I bought a big 'ol Lincoln in nice shape at an estate sale I think I paid 600, with only stick cables. It is a 250/250 AC DC tig stick, weighs?? 400 or so on casters. Yup. heavy.

You can buy import tig torches ?? about a 100 will get you going.
