I didn't say it CAN'T be done. For "on the bench" type work, TIG does a nicer job of sheet metals and gives better pool control, particularly for none-expert welders. I also said that thinner materials could be welded but you generally have to "spot" weld to avoid burning through if you're not an expert. I've welded cars with an arc welder in the past but I wouldn't recommend it.
