For easy welding MIG is the way to go. Lincoln or Miller.
It's good for just sticking things together.
AFAIK, it doesn't do stainless or the delicate/precise stuff but you can get the addon aluminum trigger assemblies for pulling wire.
I have a 110V Lincoln 135 and have welded cabinet hinges, brackets, shovels, exhaust pipe, patched body panels, etc, etc.
It's been a worthy investment which pays for itself.
