Lincoln Electric KP23-37F MIG gas nozzle
This copper gas nozzle is designed for Lincoln Electric Magnum 250LX MIG guns. It accepts a 19/50 in bore and holds the contact tip in a fixed flush position. The standard duty rating suits general MIG welding tasks. It pairs with KP14 series contact tips and KP52FN gas diffusers.
For Magnum 250LX guns using KP14 tips
Welders running a Lincoln Electric Magnum 250LX with KP14, KP14A, KP14AH or KP14H contact tips will find this nozzle a direct fit. It is not for machines that require a recessed or adjustable tip relationship. Buyers needing a different bore size or a heavy duty nozzle should look at other options.
19/50 in bore with fixed flush tip relationship
The 19/50 in bore diameter and fixed flush tip setting determine gas coverage and tip exposure. This combination is fixed by the nozzle design and matches the Magnum 250LX specification. Verify the bore and tip relationship before ordering.

Questions about this item
How do I install the KP23-37F nozzle on my Magnum 250LX gun, and what step is often missed?
Thread the nozzle onto the KP52FN diffuser until the fixed flush tip relationship seats; the step often missed is confirming the KP14-series contact tip sits flush with the nozzle end before welding.
What maintenance or replacement will the copper gas nozzle need over time?
The copper nozzle will spatter-build and erode at the .38 in bore; replace it when the inner diameter wears oversize or the fixed flush tip alignment no longer holds.
What limit appears first when running the KP23-37F at standard duty on a Magnum 250LX for long passes?
Heat saturation at the copper bore causes spatter adhesion and gas-flow turbulence before the diffuser or contact tip reaches its own thermal limit.
