OVERVIEW

The Ultimate Portable Wire Feeder Package

Take control of your welding operations with the Lincoln Electric LN-25X® Wire Feeder One-Pak® #K4266-3. Designed for welders who demand reliability and precision in the field, this package includes everything you need to start welding heavy-duty applications immediately. The kit features the legendary LN-25X portable feeder, a heavy-duty Magnum® 400 welding gun, and drive rolls optimized for .045" cored wire. Whether you are working on a skyscraper, a bridge, or a pipeline, this feeder is built to deliver consistent performance in the toughest conditions.

Wireless Control with CrossLinc®

Say goodbye to the hassle of control cables. The LN-25X utilizes Lincoln's cutting-edge CrossLinc® Technology, which enables full voltage control at the feeder without an extra cable. By communicating through the welding lead, CrossLinc puts the controls right where you need them—at the arc. This means you can adjust your settings without walking back to the power source, saving you time and energy. It also removes a major trip hazard from your work area, making your job site safer and more compliant with safety regulations.

Consistent Quality with TVT

Welding at a distance often means dealing with voltage drop, which can compromise the integrity of your welds. The LN-25X features True Voltage Technology™ (TVT) to combat this issue. TVT automatically measures the voltage drop across your cables and adjusts the power source output to compensate. If you set the feeder to 24 volts, TVT ensures you get 24 volts at the arc, regardless of how long your leads are. This results in superior weld quality and consistency, giving you confidence in every bead you lay.

Built for the Grind

The LN-25X is not just smart; it's tough. The case is constructed from a special flame-retardant and impact-resistant plastic that can survive drops and rough handling. The internal components are potted and sealed to protect against the metal dust, dirt, and moisture common in industrial environments. With a max spool capacity of 44 lbs and a high-torque drive system, this feeder is ready for long shifts and heavy wire. Upgrade your field welding setup with the LN-25X One-Pak and experience the difference that total control makes.

FAQ

CrossLinc Technology allows the wire feeder to communicate voltage settings to the power source using the standard weld power cable, eliminating the need for a separate control cable.

No, this specific One-Pak model (K4266-3) does not include a flowmeter. It comes with the K4267-2 feeder model.

TVT automatically compensates for the voltage drop that occurs over long welding cables, ensuring that the voltage set at the feeder is the actual voltage delivered to the arc.

The package includes the LN-25X feeder (K4267-2), a Magnum 400 MIG gun (K471-21), and a drive roll kit for .045 cored wire (KP1697-045C).

Yes, the LN-25X works with most CV power sources as a voltage-sensing feeder, but the remote voltage control feature will only work with CrossLinc-compatible power sources.

The LN-25X can feed solid wire up to 1/16 inch (1.6 mm) and flux-cored wire up to 5/64 inch (2.0 mm).

Yes, the case is made from flame-retardant and impact-resistant material, and the electronics are encapsulated to withstand harsh outdoor environments.
