TIG allows you to control the heat independently of the rest of the process, and how easy that is, is another mater.
I just upgraded (I hope) to a whole new TIG. You need a university degree in not reading the instructions to figure this thing out. Funny reading forums, there are so many dials, and doodads, that you get these threads where guys get crossed up cause they set slope to do one thing, low end pulse for another, starting voltage, etc... "hey this thing's broken!". Sorta like those derailleur gears that "don't work" but at three thousand degrees. I get a kick out of those folks who say TIG is done to save money, and because it's easier than pointing a torch in the general direction of a cluster of pipes.
