Reality is, I won't be doing much TIG work right now. In fact, I will be using this more to practice with than anything, as I have yet to TIG before. I've done a little gas welding, and I would like to try my hand at TIG welding. I'm not sure at this point I really need a water cooled torch, but I do understand my machine will do 250a and that can get hot pretty quickly. For right now, I will probably limit most of my TIG to 1/8-3/16" metals until I get at least a little proficient at it.
