Teaching myself TIG
So I've been learning to weld at work for the past several months. I've gotten really good and confident with 6010, 6011, 6013, and 7018 stick welding. 99.99% of the work related welding we do is stick, mild steel and very rarely we do some stainless. We have a small Hobart handler gas MIG in the corner that works well, but in 5 years I've only used it for about 10 minutes. I'm pretty sure I was the first one to turn it on in several years, as most of the guys thought it was broken. My trainer and our manager basically give me unlimited time and scrap materials to practice with (I've made some pretty cool shit since I started) and I want to slowly expand my skill set. Our smaller repair shop welder is capable of stick and TIG welding and I'd like to try TIG. The problem is my company has no use for it at this time so they won't provide the materials necessary, which is totally understandable.
My question for the experts out there is, how much do you estimate I'll have to come out of pocket to set this particular machine up for tig welding, and what brands and products would you recommend that will work well for a beginner and won't bankrupt me?
Thanks y'all.
