What's the best pick for my first welder?

Yeah I know a few people with arc units, but mostly along the lines of fixing horsr trailers and fixing tractor parts (my friend has an arc welder but the house he moved into isn't wired for 240). Looking for something than can do autobody/sheet metal, and some heavier stuff too if possible
You could make an extension cord and use the dryer plugin in the house. If it has one.
