Yes. Lincoln publishes the auxiliary AC generator output for the Maverick 325X as: Single Phase: 10 kW Continuous, 11.5 kW Peak, 120V/240V @ 60 Hz. Lincoln publishes these receptacles for this machine:
- NEMA 5-20R — 120V, 20A, NEMA 5-20R (120V / 20A / 1~)
- NEMA 14-50R — 120/240V, 50A, NEMA 14-50R (120/240V / 50A / 1~)

Yes — this is a factory demo or low-hour unit directly from Lincoln Electric. Units may show light cosmetic marks from display use but are mechanically sound. The warranty on this unit is the same as on a new machine. Lincoln’s Industrial Limited Warranty (form IMWS1, Apr-2026) lists a 3-year warranty period for “All Lincoln welding machines, wirefeeders & plasma cutting machines”, and Lincoln states: “Lincoln will assume both the parts and labor expense of correcting defects during the warranty period.” As on a new machine, the engine is not covered by Lincoln’s warranty — Lincoln states: “All engines and engine accessories are warranted by the engine or engine accessory manufacturer and are not covered by this warranty.” This machine’s Kubota D902 engine is warranted by Kubota: “USA - 2 Year/2000 Hours and 3rd Year Major Components.”, and that term “BEGINS ON DATE OF PURCHASE BY END USER.” Lincoln directs buyers to the engine maker — WWW.KUBOTAENGINE.COM.
