Mig Welder Question???

[hexafamily]

I've got a Hobart 135 with gas shield. Works good and rebuilt the floors, rockers and corners on our '72. It's a 115 volt. Works good on body panel and other light stuff, but not good for any heavy welding. Years ago tried using a flux core machine on body panels. As they say, it runs hot, splatters the weld and just real hard to use without warping something.
