I got my Furick cups for the TIG welder yesterday so I decided to weld up the Y pipe. These large torch cups are AWESOME! You do use a lot more gas though, but it is worth it with the amount of stick out you can have with the electrode. I got all but two joints finished, the TIG was starting to have some problems striking an arc as it was getting later. I told my friend who actually owns the welder and he found some info an what may be the problem. Apparently they use points for the high frequency and they can get fouled up or that part can break, but it is likely the points. I shut off the HF and was able to strike my arc with the scratch method, so when I get back to it, I will just scratch strike to finish it up.
I have to say, all the prep for TIG welding is time consuming. I had to grind some of my crappy tack welds down since I was doing overhead, in an awkward position when I was tacking up the pipes under the car. Also, I wanted to sand/smooth down all the joints and then clean them before I started TIGing. I probably spent almost 3 hours getting ready, then another 6 welding, moving the piece, re-positioning my purge setup. I understand why a good welder charges a lot for stuff like this and anyone who has ever said "X shops" stainless headers are overpriced has never done ANY TIG welding or fab,
