I agree with Grigg. It's always better to do it right the first time.
We've only recently picked up a Miller TIG, but I haven't really had a chance to play with it much yet. The go to machine is still the Millermatic 252 with .035 wire for most of the shop jobs. I just set up an old Miller 200 with .023 wire for playing with thinner stuff. I have done a few things with the Syncrowave 350 LX, enough to realize I need more practice!
