What welder will work for off-road fabrication. Hobart Handler 140?

I am looking for a decent MIG welder and came across the Hobart Handler 140. It looks nice because it says it can handle up to 1/4" and runs off a standard outlet. I will be using it for off-road fab for my Jeep. I need to weld my rear bumper to the frame and if this can handle up to 1/4" then I would think this should work. Any suggestions? I would really prefer 120V if possible. I am wanting to spend around 500 or less so if I need something stronger I will need to find something used. Any advice or any other welders to look at? I have done some MIG welding before so I have a little experience.
