hi guys, going to repair the rust on my car but just wanna know what you guys do to keep the panel from bending with the heat? Just stitch it?

The problem with stitching when using a tig welder is that you lose the great benifit of having a tig welder. Stitching with a mig is acceptable and the right way to do it, because of the brittle nature of the mig weld its more difficult to stretch the shrinking of the weld, so stitching will give you less shrinking. But the tig has a soft weld very similar to torch welding, so it can be planished without fear of cracks, so you can do a continuous weld, then go back and stretch with a hammer and dolly. I learned to planish my weld areas without too much trouble, after practicing only about two weeks, so most people can learn this and get the panel stretched back out close to original contour and use less bondo. If you only intend to stitch weld, then the mig welder does shrink less than the tig, and would be better.
Tim I was trying to maintain some respect for ODG by not responding, try to do the same please. I have posted this same opinion many times on this forum, so the OP only had to do a search to find it.
And this post is two months old, get a life.
