KP24A-50 - Lincoln KP24A-50 Adjustable Slip-On MIG Nozzle 1/2" Bore

Lincoln KP24A-50 Adjustable MIG Nozzle

Optimize your welding performance with the Lincoln Electric KP24A-50 Gas Nozzle. Designed as a direct replacement for Magnum 300 and 400 amperage MIG guns, this nozzle is an essential consumable for professional welders seeking reliability and precision. The nozzle features a standard 1/2-inch bore, which provides an optimal balance of gas flow and access to the weld joint, making it suitable for the majority of medium-to-heavy duty MIG welding applications.

The slip-on adjustable mechanism of the KP24A-50 sets it apart from standard fixed nozzles. This feature allows the welder to slide the nozzle up or down the diffuser, effectively changing the contact tip recess. This capability is particularly useful when switching between different welding parameters or joint types. For instance, a recessed tip is often preferred for higher current spray transfer to protect the tip from heat, while a flush or sticking-out tip might be used for short-circuit welding or tight fit-ups. The KP24A-50 gives you the control to adapt your gun to the job at hand.

Genuine Lincoln Electric consumables are manufactured to strict tolerances to ensure consistent gas flow and arc stability. Using the correct nozzle helps prevent porosity and ensures that your shielding gas—whether CO2 or an Argon mix—is delivered smoothly to the arc zone. The robust construction handles the thermal cycles of industrial welding, and the smooth surface finish helps minimize spatter adhesion, making post-weld cleaning of the nozzle easier. Keep your Magnum gun running at peak efficiency with this versatile 1/2" adjustable nozzle.
