Whichever method you decide to use, be sure to use the right size filler material, it will reduce burn through and other issues that might arise. I like 0.024-inch wire for MIG and 1/16-inch rod and tungsten for TIG. If you're still having problems with burn through, grab a piece of flat copper and use it to back the weld seam. Works great when filling holes as well. Tack the panel in and then alternate the location of each weld and keep them less than an inch in length, should keep the heat down to a minimum if you're moving and not sitting in one place too much. Good luck!
