Shifty
I had a friends LINCOLIN 135 worked an 115 volts. It did all the welding I was doing. For frame work you want continuse welding if your new at welding try to find someone experienced with these frames I only stretched semi frames which had to be plated in and out. As far as panel welding I always tack or spot weld then stitch about 1-2 inches at a time eliminates a lot of worpage. The snap-on I have now is a little bigger than I need but I think the price was right.
Good Luck finding one
