The Lincoln Factory Demo Vantage 441X Engine Driven Welder Perkins, part number U4535-1, is the powerhouse solution for demanding industrial welding and power needs. Designed to handle heavy-duty applications, this machine delivers up to 520 amps (IEC rated at 400 amps) of welding output and 17 kW of continuous three-phase auxiliary power. The Vantage 441X is powered by a reliable 41.0 HP turbocharged Perkins® diesel engine, providing smooth and quiet operation, even in cold-weather or high-altitude environments, while meeting EPA Tier 4 Final compliance standards.
Equipped with advanced features such as CrossLinc® Technology, the Vantage 441X allows welders to control voltage and current directly at the arc through standard weld cables, enhancing safety and productivity. Patented Chopper® Technology ensures consistent arc performance with reduced spatter and improved gouging capabilities, making it an ideal choice for Stick, TIG, MIG, Flux-Cored, and arc gouging applications. With expanded welding modes for stainless steel, aluminum, and advanced pulse welding, this machine is engineered for versatility and precision.
This factory demo unit has been field-proven to deliver reliable performance and durability, ensuring it's ready to meet the challenges of your next job.

Yes. Lincoln publishes the auxiliary AC generator output for the Vantage 441X as: Single Phase: 11 kW Continuous, 120V/240V @ 60 Hz; Three Phase: 17 kW Continuous, 240V @ 60 Hz (Single Phase 120V/240V @ 60 Hz; Three Phase 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~)
- NEMA 15-50R — 240V, 50A, NEMA 15-50R (240V / 50A / 3~)

The Vantage 441X on this listing is powered by a Perkins 404F-E22T, turbocharged, Tier 4 Final diesel engine, 41.0 hp. Perkins engines in this line are diesel only. Source: Lincoln spec sheet E6.421.1.
Duty cycle varies by output setting. The Vantage 441X is a 100% duty cycle machine at its 400 A / 36 V IEC rating, but only 60% duty cycle at its 520 A / 30 V maximum rating — so running it flat out is not continuous-duty operation. Both ratings are at 104°F (40°C).

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 Perkins 404F-E22T engine is warranted by Perkins: “Two Years on parts and labor on 100 and 400 series (2,000 hours) and 1000 and 1100 series (3000 hours). Three years major components, worldwide.”, and that term “BEGINS ON DATE OF PURCHASE BY END USER.” Lincoln directs buyers to the engine maker — WWW.PERKINS.COM / 1-888-PERK-ENG (737-5364).
