I borrowed a friends SP135 welder for a few weeks just before I got my 255. While it's rated at 20 amps input you really needed to have it on a 30 amp circuit. The chart inside it said it would weld up to 5/16 with multiple passes using flux core wire. But I found it to be a pain having to stop and remove the flux between passes would allow the metal to cool. As others have said, 110v machines have a limited amount of "heat" they can put into metal.
SP135 is a good little welder. That is what I learned on.
