Miller generator welder with a Onan engine. Haven't used it in awhile, ran great if you took the oil bath air cleaner off so it either needs a different air cleaner or the carb adjusted a little. AC/DC welding. 240 or 110 power. 240 outlet broke years ago and we just taped the wires off as we used it for jobsight welding and just used the 110 power for power tools. Has welding leads. As is, motor is free. $295 cash only.
