There are a couple of TIG accessories that I would recommend. It's well worth having a number 9 torch (the small ones) with one of those supersoft red CK hoses, and you will certainly need a foot pedal. I don't use auto-pulse although some people like it. I've experimented with huge cups and lots of stickout but it doesn't work for me but maybe just because I'm too mean to crank the gas up enough. I use a No 8 cup for everything with 1/16" electrode. For the tight spots I use a big stickout but wrap tinfoil around the place to trap Argon and sort of fill the area up for a few seconds before starting. Fiddly but works well. And you will want a thin filler rod. I use 1mm but some people use really thin MIG wire.
