I am seriously considering buying a mig welder, but all the welding I need to do at the moment is seriously thin steel on my car. Nothing is structural, it is the very thin joining panels between parts of the chassis that are there just to fill a hole that have corroded. Nobody bar me will ever know it is there, however I'd rather weld it for piece of mind. Bearing this in mind and a relatively small budget what is recommended? My budget isn't huge and due to the relatively small amount of welding I need doing I can't justify spending much. I would borrow a friends welder again but the power doesn't go down low enough.
