Lincoln Electric Power MIG 215 MPi Multiprocess Welder with Aluminum One-Pak
This Aluminum One-Pak from Lincoln Electric builds on the Power MIG 215 MPi dual-voltage multiprocess welder, which runs on 120 V or 230 V and covers MIG, flux-cored, stick and DC TIG, and adds included accessories with an emphasis on aluminum MIG welding. It targets general fabrication, small contractor operations and repair.
The power source reaches 220 A on 230 V and 140 A on 120 V, with MIG rated at 215 A, 24.8 V and 30% on 230 V. Its Ready.Set.Weld system recommends wire feed speed and voltage from the material type and thickness, and the ArcFX display shows the recommendations.
TIG readiness is built in through a TIG solenoid and a foot pedal adapter. The case has lift points that make the unit easier to move around the shop, the wire drive feeds consistently across wire types and diameters, and the aluminum-specific accessories in this One-Pak support aluminum MIG welding from the start.
