OVERVIEW

Lincoln K126 PRO Innershield Gun: The Construction Standard

When it comes to structural steel erection and heavy fabrication, the Lincoln Electric K126® PRO Innershield® Welding Gun is the tool professionals trust. Known for its rugged reliability, the K126-13 model delivers 350 amps of welding power with a 15-foot reach, giving you the freedom to move around large assemblies and job sites without compromising arc stability. Whether you are welding bridge beams, barge decks, or heavy machinery, this self-shielded flux-core gun is built to perform in the harshest environments.

Built for the Welder, Designed for the Field
Lincoln Electric has taken feedback from fifty years of field use to create the PRO series. The result is a gun that feels familiar but works better. The K126 PRO features a robust replaceable liner system, a game-changer for field maintenance. If your wire starts dragging, you can simply replace the liner instead of tossing the whole gun. The included Magnum® PRO Copper Plus™ contact tips are designed to last longer and run cooler, meaning fewer trips to the tool crib and more arc-on time.

Superior Protection and Ergonomics
Snagged trigger wires are a thing of the past. The K126 PRO hides the trigger leads inside the heavy-duty coaxial cable, protecting them from cuts, burns, and abrasion. The stainless steel armored gun tube sheds spatter easily, keeping your equipment clean and electrically safe. The K126-13 comes standard with a 30-degree non-reverse bend tube, perfect for general purpose welding, but the system is modular—you can rotate the tube for better angles or swap it out for different bend configurations if your job requires it.

Ready to Weld
This package (K126-13) arrives ready to run 5/64" Innershield wire right out of the box. It includes the necessary tip, liner, and Lincoln-style connector. If your work demands different wire sizes, the gun is rated to handle everything from .035" up to .120", making it a versatile asset for any heavy industrial fleet. Invest in the gun that defines the category—the Lincoln K126 PRO.
