Lincoln Flextec 350X Construction / LN-25X One Pak - K4278-3
The Lincoln Flextec 350X Construction / LN-25X One-Pak system delivers exceptional field welding performance through the integration of advanced CrossLinc Technology, enabling remote parameter control without additional control cables. This comprehensive welding solution combines the rugged Flextec 350X Construction power source with the portable LN-25X wire feeder and Lincoln's premium Magnum PRO Curve HDE welding gun, creating an optimized system for demanding field applications. The unified One-Pak configuration streamlines ordering through a single part number, ensuring all components work seamlessly together right from delivery.
Engineered specifically for harsh environments, this system features trayed and potted PC boards with an IP23 environmental rating, providing superior protection against dust, moisture, and vibration commonly encountered in construction and field erection settings. The revolutionary CrossLinc Technology enables operators to adjust welding parameters directly at the wire feeder hundreds of feet from the power source without cumbersome control cables, significantly improving productivity and weld quality in remote locations. Additionally, the True Voltage Technology (TVT) automatically compensates for voltage drop in long cable runs, ensuring the actual welding voltage matches the preset value.
The portable LN-25X wire feeder features a durable construction with protected meters for parameter monitoring and adjustment in field conditions. Combined with the ergonomic Magnum PRO Curve HDE gun, the system reduces operator fatigue during extended welding sessions while maintaining consistent wire feeding performance. Supporting multiple welding processes including MIG, Flux-Cored, Stick, TIG, and Gouging applications, this versatile system adapts to diverse project requirements across construction, pipeline, fabrication, and maintenance operations. The Flextec 350X Construction / LN-25X One-Pak represents an ideal solution for contractors and fabricators requiring reliable, high-quality welding capabilities in challenging field environments.
