K4101-2 - Lincoln LN-25 PRO Wire Feeder One-Pak with K126 PRO Gun

The Ultimate Field Welding Package

Take your welding operations to any job site with the Lincoln Electric LN-25 PRO / K126 PRO One-Pak. This all-in-one bundle combines the legendary toughness of the LN-25 PRO suitcase wire feeder with the performance of the K126 PRO Innershield gun. Designed for welders who demand reliability in the toughest conditions, this package is ready to tackle construction, pipe welding, and heavy repair work right out of the box.

Built Tough for the Job Site

The LN-25 PRO is famous for being virtually indestructible. Its rugged, flame-resistant case protects the wire and mechanism from dirt, rain, and job site knocks. Whether you are high up on steel beams or down in a trench, the portable design ensures you can bring wire welding productivity exactly where you need it. The feeder uses the arc voltage to power itself, meaning you only need a welding lead from your power source and a work lead to get started—no control cables required.

Precision and Control

Feeding wire smoothly is the key to a good weld, and the MaxTrac drive system delivers. With a dual-range speed control, you can dial in the exact settings you need, whether you are welding thick structural steel or performing delicate repair work. The included K126 PRO gun is rated for 350 amps and is designed specifically for flux-cored wire, featuring a comfortable grip and a trigger interlock that lets you relax your hand during long welds.

Everything You Need

Stop searching for compatible parts. The K4101-2 One-Pak includes the feeder, the gun, and the specific drive rolls needed for 1/16" and 5/64" flux-cored wires. It is the perfect upgrade for your engine drive welder or shop power source, turning it into a high-performance wire welding station. With potted electronics that resist moisture and a case that can be swapped out if damaged, this investment is built to last for years of profitable work.
