If you can run a full weld pass on flat 18 gauge with a TIG without significant warping, you are the man. I can't wait to see the video.
I am still impressed with the video showing the high amp quick zap for the tack welds. While that notion crossed my mind when I was overheating my panels with a lower amp setting, I never had the stones to experiment with it.
Carl, think of your speed as a heat control. By using the lower heat setting you are possibly sitting there longer and widening the Heat Affected Zone. The welds I did this evening still had the machine set at 70 amps, and used a faster torch travel to control realized heat at the panel. HAZ was relatively narrow. Next, starting and stopping, regardless of the process, is where you see most distortion added. So if we can use a process that is more user friendly to a full weld pass (TIG or O/A) we can eliminate another source of distortion....
