This looks in good shape.

“1954 Hobart G200 D/C welder on trailer. Uses a CJ2A four cylinder Jeep engine. There is also a 120 volt outlet on the machine for running your power tools. The machine was just restored. Valves and valve seats were reconditioned, fuel and oil lines replaced, new belts, hoses and tune up parts. Generator bearings were repacked, brushes were replaced, radiator was cleaned and pressure checked. Body panels were stripped to bare metal and repainted with automotive paint. Machine was thoroughly tested and runs and welds perfect. Is ready to weld for another 56 years”
