Miller CCKA model welder w generator

So I bought this welder/generator at an auction because I really just wanted some other other items. Probably can use the trailer but Im not a welder I am charging- probably replacing -the battery and have ordered new spark plugs Im told it runs but I haven't tried it yet. Draining the gas tank first. Its been under a covered shed but pawpaw hasn't used it recently. If you have interest and we can get it running lets make a deal. Maybe even include the trailer -no title -but its stout as you can see $250 for the welder. Only $750 for the whole package Miller AEAD-200LE AC/DC welding and power generator (serial number HE791392) powered by an Onan engine, rated at 5 kVA, 120/240V AC, and 1,800 RPM with 115V DC auxiliary power (has 240 plug inside cover) . Surface rust. It was an estate type auction and no one from the family was available to give me much of the provenance. The unit is mounted on a heavy duty single-axle diamond-plate (4x8?) utility trailer equipped with DieHard battery, trailer tongue with coupler, safety chains, No welding leads. The unit it not affixed to the trailer. It was chained/cabled to the surface. Did I say the trailer is stout? Its really stout.
