KP2085-1 - Lincoln Magnum PRO Fume Gun Flux Cone Adapter

Optimized Fume Extraction for Self-Shielded Applications

The Lincoln Electric KP2085-1 Flux Cone is a critical component designed specifically for the Magnum® PRO line of Fume Extraction Guns. In industrial environments where air quality control is paramount, fume extraction guns are utilized to capture particulate matter directly at the source. However, standard configurations often assume the use of shielding gas. When operators switch to self-shielded flux-cored arc welding (FCAW-S), the standard gas nozzle becomes redundant and can potentially hinder the efficiency of the vacuum system or obscure the operator's view. The KP2085-1 Flux Cone addresses this engineering challenge by replacing the gas nozzle entirely.

This component serves a dual purpose: protection and aerodynamic optimization. Firstly, it threads onto the front end of the gun, covering the gas diffuser and retaining head threads. This shielding is vital in FCAW-S processes, which are characteristically higher in spatter generation than gas-shielded processes. Without the flux cone, spatter would adhere directly to the threads, making future maintenance or consumable changes difficult and potentially damaging the gun's front end. Secondly, the geometry of the flux cone is engineered to work in concert with the fume extraction shroud. By maintaining the correct spacing and profile, it ensures that the vacuum velocity is maintained around the arc zone, effectively capturing fumes without the turbulence or obstruction that an empty gas nozzle might create.

Manufactured to Lincoln Electric's rigorous standards, the KP2085-1 is built from high-heat resistant materials capable of withstanding the intense thermal cycles associated with heavy-duty flux-cored welding. It is an essential accessory for fabrication shops, shipyards, and construction sites utilizing Lincoln fume extraction systems with Innershield® wires. Proper installation of this cone ensures compliance with safety protocols regarding fume capture while extending the service life of the welding gun's front-end components.

Technical Compatibility

The KP2085-1 is compatible with specific models within the Magnum PRO Fume Gun series. It is not a universal fit for all Magnum guns but is tailored for the fume extraction variants where the shroud and nozzle geometry differ from standard MIG guns. Users should verify their specific gun model to ensure proper fitment and function.
