The Lincoln Electric LN-25X® Wire Feeder One-Pak® (K4266-3) represents a significant leap forward in portable wire feeding technology, specifically engineered for the demanding environments of construction, shipbuilding, and heavy fabrication. This comprehensive package pairs the robust LN-25X feeder with the industry-proven Magnum® 400 MIG gun, providing a ready-to-weld solution for high-amperage applications. The unit is designed to withstand the rigors of the job site, featuring a flame-resistant, impact-resistant case and fully encapsulated electronics that are protected against moisture, dust, and vibration.
The defining feature of the LN-25X is CrossLinc® Technology. In traditional field welding, operators often face a choice between using a simple "across-the-arc" feeder with no remote control or dealing with the clutter and fragility of an additional control cable. CrossLinc solves this by transmitting voltage control signals directly over the standard welding power cable. This allows the welder to adjust voltage settings at the feeder—hundreds of feet away from the power source—without the trip hazard or maintenance liability of a control cord. This innovation significantly improves safety by reducing job site clutter and enhances productivity by eliminating unnecessary trips back to the power source.
Long cable runs in field applications inevitably lead to voltage drop, where the voltage at the arc is lower than what is set at the machine. This can result in cold welds and lack of fusion. The LN-25X is equipped with True Voltage Technology™ (TVT), which actively monitors the voltage at the feeder. It automatically signals the power source to adjust its output, compensating for the drop and ensuring that the voltage you set is exactly the voltage delivered to the weld. This guarantees consistent weld quality and reduces the need for rework.
The LN-25X is built for versatility, capable of feeding solid wire up to 1/16 inch (1.6 mm) and cored wire up to 5/64 inch (2.0 mm). The Maxtrac® wire drive system ensures reliable feeding performance, while the wide wire feed speed range of 50-700 IPM accommodates a variety of welding procedures. This One-Pak includes the feeder, the Magnum® 400 gun, and a drive roll kit for .045" cored wire, making it an ideal choice for structural steel erectors and field maintenance crews.
