This is where I made a quick slice in the x-pipe. This was necessary because the tunnel that the exhaust and driveshaft run through wasn't wide enough to fit the "bolt-in" exhaust.
This is how much I had to take out of it to make it fit in there.
I have never TIG welded before, so I had to grind down the welds on the headers. After globbing on the stuff there, I think I actually got the idea behind it. Vince, maybe you can input here (or anyone else who does it and can hand out some pointers). I'll take some photos when I weld up the x-pipe, and we'll see how much improvement I make. I think the torch part of the welder is more to "push" the weld along. The stick is just to feed enough in to keep the puddle going.
It's not like MIG. MIG welding I usually push the puddle along with the wire that's being fed through the gun.. since the fed wire has the voltage passing through it. I guess it makes sense then, now that I type it out, that the TORCH pushes the puddles along since the torch on a TIG has the voltage running through it.
