K549-2 - Lincoln Electric Innershield Welding Kit .045" for Magnum 100L

Complete Flux-Cored Conversion for Magnum 100L

The Lincoln Electric K549-2 Innershield Welding Kit is the ultimate solution for welders looking to convert their Magnum® 100L MIG gun for use with .045-inch (1.2 mm) flux-cored wire. Whether you are tackling outdoor projects where shielding gas is impractical or need the deep penetration characteristics of flux-cored welding, this kit provides every component necessary for a seamless transition. Designed by Lincoln Electric, a leader in welding technology, this package ensures compatibility and performance.

One of the standout features of this kit is the inclusion of a 10 lb (4.5 kg) spool of Innershield® NR-211-MP wire. This versatile self-shielded wire is renowned for its ease of use and ability to handle a variety of applications, from general fabrication to maintenance repairs. By bundling the wire with the necessary hardware, Lincoln Electric eliminates the guesswork involved in sourcing individual parts, allowing you to get to work immediately.

The kit addresses the specific mechanical requirements of feeding flux-cored wire. It includes a knurled drive roll specifically designed to grip the softer tubular wire without crushing it, ensuring consistent feeding and stable arc performance. Additionally, the included cable liner is sized perfectly for .045" wire, preventing drag and bird-nesting that can occur with improper liners. A gasless nozzle and contact tip round out the hardware, protecting your equipment and ensuring optimal electrical conductivity.

Ideal for both hobbyists and professional fabricators, the K549-2 kit transforms your standard MIG setup into a powerful flux-cored machine. It is particularly useful for users who need to weld on dirty or rusty materials where flux-cored wire excels. With genuine Lincoln Electric parts, you can trust in the durability and reliability of your equipment setup.
