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 Kohler Command ECH749 EFI engine is warranted by Rehlko (formerly Kohler): “Three Years”, and that term “BEGINS ON DATE OF PURCHASE BY END USER.” Lincoln footnotes the Rehlko (formerly Kohler) three-year term “First owner only.” The air compressor is warranted by VMAC: “Three years or 3,000 hours (whichever comes first) from the date of delivery of the compressor to the first owner.” Lincoln directs buyers to the engine maker — WWW.ENGINES.REHLKO.COM / 1-800-544-2444 Rehlko Service Department.
