This welder is part of Lincoln’s trusted Used Welder Program. These units have been lightly used—either as demo models or for short-term applications—and then returned to Lincoln for a complete factory inspection. All accessories are replaced with brand-new components, and the unit is fully tested to meet Lincoln’s high performance standards. Each welder is shipped to us factory-sealed and includes the full manufacturer’s warranty, just like a brand-new model—offering exceptional value without compromising on quality or peace of mind.
