Well, most of what I'll be doing in the near future will be sheet steel or relatively thin aluminum. The garage actually has 60 amp service, but off of an old fuse panel. Getting 240 in would be prohibitively expensive (Somewhere around $800 just for a single outlet), so I'm hoping to do most of the sheet metal work and if I really need more amperage I can run a temporary cable from the house, if I really have to. In the future I'll pay more attention and try to get 240v in the garage, but for now I'd like something that can handle the sheet metal work and such I've got without constantly having to run a line out.
