K549-4 - Lincoln Electric .045 Innershield Conversion Kit for Magnum 100L

Go Gasless with the Lincoln K549-4 Kit

Take your welding projects outdoors and tackle thicker materials with confidence using the Lincoln Electric K549-4 Innershield Welding Kit. Designed specifically for owners of welders equipped with the Magnum® 100L gun, this kit is the ultimate upgrade for those looking to utilize the power and convenience of flux-cored welding. Flux-cored welding (FCAW-S) does not require an external shielding gas tank, making it the perfect process for welding in windy conditions, on dirty steel, or when portability is a priority. This kit takes the guesswork out of the conversion process by providing every single part you need in one box.

Everything in One Box

Forget about searching through parts diagrams to find the right liner or drive roll. The K549-4 kit is a "plug-and-play" solution. It comes complete with a heavy-duty 10 lb. spool of .045 inch wire, a new liner to prevent wire drag, a specific contact tip, and a gasless nozzle. The gasless nozzle is a key addition; it replaces your standard MIG nozzle, offering a slimmer profile that lets you see exactly where you are welding, which is crucial for maintaining a tight bead in difficult angles.

The Power of NR-211-MP

Included in this package is the legendary Innershield® NR®-211-MP wire. This is not just any wire; it is a multi-position, general-purpose wire that is forgiving and easy to use. It is excellent for welding on galvanized sheet metal and general structural steel. Because it is self-shielded, you don't have to lug around a heavy gas cylinder, making your welding rig significantly lighter and more mobile. The .045 inch diameter allows for higher deposition rates, meaning you can finish your welds faster and with better penetration compared to thinner wires.

Designed for the Magnum 100L

Compatibility is key, and this kit is OEM-specified for the Magnum 100L gun found on many popular Lincoln welders. The included knurled drive roll is a game-changer for feeding flux-cored wire. Unlike smooth rolls that rely on tension that can crush hollow wires, the knurled teeth grab the wire gently but firmly, ensuring a consistent feed speed even when the cable is bent or twisted. With the incoming and outgoing guides also included, you ensure a snag-free path for the wire from the spool to the arc.
