Plug Weld Floor Pans?

I just plug welded my floor in with my inexpensive Eastwood 135 on the bottle. I am not a welder, but made it work ok- learned a lot in the process. Trunk floor is next. If you have a buddy with a MIG, see if you can borrow it or buy him a case of beer to do it for you. I do this often with my buddy that has a higher amp MIG/TIG combo.
