The Lincoln Electric AlumaFab® 350 is a purpose-built aluminum MIG welding system designed for high-volume production and fabrication environments. Developed through a strategic partnership between Lincoln Electric and MK Products, this system combines advanced power source technology with industry-leading push-pull wire feeding to deliver smooth, consistent aluminum welding performance.
Engineered specifically for aluminum applications, the AlumaFab 350 simplifies the welding process with a stable, forgiving arc and an operator-friendly interface. Its streamlined design allows welders of all skill levels to achieve high-quality results while minimizing setup time and reducing common aluminum welding challenges such as wire feeding issues. :contentReference[oaicite:0]{index=0}
The AlumaFab 350 is available in two primary system configurations based on cooling requirements:
- K6013-1 (Air-Cooled Package) – Complete system including power source, feeder, controller, cart, work lead, and regulator for standard aluminum welding applications
- K6014-1 (Water-Cooled Package) – Includes all air-cooled components plus the Cool Arc® 55 water cooler for extended duty cycle and high-amperage applications
Both configurations require a compatible push-pull welding gun (sold separately), allowing users to customize the system based on cable length and cooling preferences.
