K4023-1 - Lincoln Power MIG 350MP Aluminum One-Pak Multi-Process Welder

The Ultimate Aluminum Welding Station

The Lincoln Electric Power MIG 350MP Aluminum One-Pak (K4023-1) is designed for fabricators who demand precision, speed, and versatility, particularly when working with aluminum. This comprehensive package takes the industry-leading Power MIG 350MP platform and equips it with everything necessary for high-performance aluminum welding right out of the box. Whether you are manufacturing trailers, repairing aluminum hulls, or performing general fabrication, this machine offers a level of control and weld quality that stands apart from standard MIG welders.

At the heart of this system is Lincoln's advanced Pulse-on-Pulse® technology. This feature modulates the welding arc to create a "stacked dime" appearance traditionally associated with TIG welding, but with the travel speed and productivity of MIG. This is critical for aluminum applications where aesthetics and heat control are paramount. Additionally, the Power Mode® feature ensures a stable, smooth arc for short arc welding on steel and provides improved penetration on thicker aluminum sections, giving you the flexibility to handle diverse projects without switching machines.

The One-Pak configuration is a massive value-add for shops. It includes the Magnum PRO AL Push-Pull Gun (G225A) with a 25-foot reach, which is essential for feeding soft aluminum wire reliably over long distances without bird-nesting. Combined with the included SuperGlaze 5356 wire and specific aluminum drive rolls, you are ready to weld 4XXX and 5XXX series alloys immediately. The machine also retains full multi-process capability for steel and stainless steel, making it a true all-in-one workshop solution.
