- Mixed-process shops — switch between MIG, Stick, and TIG without owning a second machine
- Mobile contractors — multi-voltage input runs on shop 230V or jobsite 120V
- Auto body and light fabrication — 0.025" wire capability handles thin sheet metal cleanly
It supports MIG, DC TIG, Stick, Flux-Cored.
95A/18.75V/60% MIG, 115A/14.6V/60% TIG, 80A/23.2V/60% Stick. This means continuous welding at that amperage for the listed percentage of a 10-minute cycle before requiring cool-down.
120V (115V/1/60) on single-phase power.
0.025 - 0.035 in (0.6 - 0.9 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.
