I've got an '82 Roughneck for sale. I started out with one of these, a great little machine but it's AC only. Electric start, 3.5 KVA of 110/220. Not dented, doesn't smoke. A good little farm machine. The AC runs suprisingly well because it runs at 130Hz twice the 60Hz of the buzz boxes.
I bought this so I could put it in a row boat and get around to some of the docks that others couldn't. Some guy was there with his 400 amp duelly rig and 500 ft of cable and couldn't get to all the places. I showed up with a Toyota and a borrowed rowboat and welded all the parts that he couldn't reach. I was able to charge more than him.
