KP1939-1 - Lincoln KP1939-1 Gasless Nozzle for Magnum 100L MIG Guns

Essential Protection for Gasless Welding

The Lincoln Electric KP1939-1 Magnum PRO Flux-Cored Nozzle is a critical accessory for welders utilizing the self-shielded flux-cored process. Designed specifically for the popular Magnum 100L and Magnum PRO 100L MIG welding guns, this nozzle serves a unique purpose distinct from standard gas nozzles. When welding with flux-cored wire (often referred to as Innershield), shielding gas is not required. However, leaving the end of your welding gun exposed can lead to significant damage. The KP1939-1 acts as a protective shield, covering the gas diffuser and the threads of the contact tip holder.

Without this specialized nozzle, molten spatter generated during the welding process can adhere to the delicate threads of your gun's front-end consumables. Over time, this buildup can fuse components together, making it difficult or impossible to change contact tips or diffusers without damaging the gun. The KP1939-1 prevents this issue by providing a heat-resistant barrier that deflects spatter while maintaining the electrical insulation of the gun's tip. This ensures that your equipment remains in top working condition, extending the lifespan of your torch and reducing maintenance downtime.

Furthermore, using a standard gas nozzle during flux-cored welding can sometimes be detrimental. Standard nozzles are designed to funnel gas, and their larger profile can obstruct your view of the weld puddle and trap smoke. The KP1939-1 Gasless Nozzle features a streamlined design that improves visibility, allowing for more precise bead placement. It is an indispensable tool for hobbyists, DIY enthusiasts, and professionals who rely on the versatility of gasless MIG welding for outdoor projects or repairs on dirty steel. Whether you are working on automotive body panels or fixing farm equipment, this genuine Lincoln Electric part ensures your Magnum 100L gun performs reliably.

Installation is straightforward and tool-free. Simply remove the existing gas nozzle used for solid wire welding and slide or screw the KP1939-1 into place over the diffuser. Its secure fit ensures it stays in place during operation but can be easily removed for cleaning or tip changes. Invest in the right consumables for your process and protect your welding investment with this high-quality flux-cored nozzle.
