I spot weld the panel in with MIG then finish weld with TIG. If you want to use a MIG, spot weld the panel in, then spot between the spots bouncing from end to end and you could stop and cool with an air gun. Keep adding spots between the existing spots until the weld is complete. The point is to not build any more heat than necessary in any one place. That is why you only spot weld then move to another area to do the next spot and so on. Then when you grind down the spots just respite any places that you may have missed.
