5-25-09: I haven't done a whole lot of welding on sheet metal. I set up my welding according to the chart under the lid. Then I tried to do a few tack welds. I kept blowing thru the metal. So I turned the voltage setting down to the lowest setting ( was on the second to lowest setting ) . I tried again and it worked much better. So I started doing a bunch of tack welds moving to different areas for each tack until I had a solid bead. It might not look too pretty but that's what they make grinders for!
