Got a TIG at work, I can already oxy/arc weld, have been for years, so once you know the settings to use on a TIG its sort of like using an electric oxy, I have used one a couple of times before.
My problem is that I am sh!tloads of miles from anywhere and if I wnat the job done I've got to do it myself - there is nobody around here that does this sort of thing. Anyway, its way cheaper to buy in some bends and bits that I want and cut and shunt them myself than it is to get someone to do it, probably cost $2-300 for the stainless tubing and flanges etc. Thats peanuts for a s/s custom system.
