- Production MIG welding — built for high-output continuous MIG work on mild steel and stainless
- Fabrication shops — runs flux-cored self-shielded wire for outdoor and dirty-metal applications
- Light-to-medium structural — handles 3/16" to 1/4" base metal with appropriate wire selection
It supports MIG, Flux-Cored.
40% @ 250A. This means continuous welding at that amperage for the listed percentage of a 10-minute cycle before requiring cool-down.
208/230/460/575V on single-phase power.
0.025 - 3/64 in (0.6 - 1.2 mm) — covers standard MIG wire sizes from sheet metal through medium structural work.
This machine carries Lincoln Electric’s standard warranty period of 3 years, parts and labor — the same coverage as a new machine. Lincoln’s Industrial Limited Warranty (form IMWS1, Apr-2026) lists 3 years for “All Lincoln welding machines, wirefeeders & plasma cutting machines” and states: “Lincoln will assume both the parts and labor expense of correcting defects during the warranty period.” Consumables and contact tips are wear items not covered by warranty.

This Lincoln POWER MIG® 260 MIG Welder is a Lincoln Electric factory demo unit — used in controlled demonstration or training environments, then returned to Lincoln Electric for inspection and certification. It has not been operated in a production environment. Lincoln Electric factory technicians verify all demo units meet new-machine performance standards before sale through Authorized Dealers.
- Low hours — demonstration use only, not production-operated
- Factory-inspected and certified by Lincoln Electric technicians
- Priced below new retail — the same capable machine at real savings
- Ships from WeldingMart with full factory packaging

40% @ 250A. Duty cycle is measured over a 10-minute period — the percentage indicates how many minutes of continuous welding at that amperage before a cool-down period is required.
Lincoln Electric factory demo units are machines used at trade shows, training centers, and authorized customer demonstrations — never run in a production environment. After use, they are returned to Lincoln Electric, inspected by factory technicians, and certified to new-unit performance standards. WeldingMart is an Authorized Lincoln Electric Dealer offering these units directly.
