Who this suits and who should look elsewhere
Welders running Lincoln Magnum 400A or Magnum 300 guns who need a replacement 1/2 in conical nozzle will find this part matches the original specifications. Buyers using guns with different thread patterns, bore sizes, or nozzle shapes should look at something else because the connection and geometry will not match.

Questions about this item
What does the 400 A rating mean when the nozzle is fitted to a Magnum gun?
The 400 A rating is the maximum amperage the KP23-50F nozzle can handle on a Magnum 400 A gun without overheating the tip or bore.
How does the threaded connection affect gas coverage and tip life?
The threaded connection locks the conical nozzle flush to the contact tip, keeping shielding gas focused and preventing tip recession during high-amperage passes.
What gun models and series accept the 1/2 in bore KP23-50F nozzle?
It fits Magnum 300 and Magnum 400 series guns including models K1722-2, K1802-1, K2286-1, K470, K471, K479, K541-3 and K575-2.
