K225 - Lincoln Electric Large Wire Twinarc Nozzle Kit for Submerged Arc Welding

Lincoln Electric K225 Large Wire Twinarc Nozzle Assembly

Boost your welding operations with the Lincoln Electric Large Wire Twinarc® Kit (K225), a premium solution for high-deposition submerged arc welding. This kit is designed to facilitate the Twinarc process, which feeds two electrode wires into a single arc zone, effectively doubling the electrode surface area and significantly increasing melting rates. It is specifically tailored for larger wire sizes, accommodating 5/64", 3/32", and 1/8" diameters. This makes it the perfect choice for heavy-duty applications such as creating "Fast-Fill" joints or laying down extensive hardfacing beads on wear parts. The K225 is compatible with Lincoln's industrial standard NA-3S, NA-4, and NA-5 control units, provided they are fitted with a 142/1 gear ratio.

The K225 is not just a nozzle; it is a complete conversion ecosystem. Inside the box, you will find everything needed to set up your equipment for dual-wire welding. This includes a wire reel and mounting bracket, ensuring the second wire is fed smoothly alongside the first. The kit also contains the necessary drive rolls and idle roll assembly to propel the wire, along with a wire straightener to ensure straight, accurate tracking into the weld puddle. The contact nozzle itself is a masterpiece of engineering, featuring dual wire guides and a contact block equipped with spring-loaded jaws. These jaws are critical for maintaining consistent electrical conductivity, preventing voltage fluctuations that could lead to defects. The result is a stable, high-energy arc that deposits metal rapidly and efficiently.

For shops looking to maximize the potential of their submerged arc equipment, the K225 offers a direct path to increased productivity. Whether you are welding thick-walled pressure vessels, bridge girders, or resurfacing crusher rolls, the ability to run two large wires simultaneously can dramatically cut down welding time. The Twinarc process allows for higher travel speeds and better gap bridging capabilities compared to single-wire SAW. Trust in the quality of Lincoln Electric genuine parts to keep your automated welding systems running at peak performance. This kit ensures that your setup is optimized for the heavy electrical loads and mechanical demands of high-amperage twin-wire welding.
