Lincoln Electric KP23-50F Gas Nozzle

The Lincoln Electric KP23-50F is a conical gas nozzle with a 1/2 in bore diameter and threaded connection. It is built for Magnum 400A and Magnum 300 series guns and rated to 400 A maximum amperage with a flush nozzle-to-tip relationship.

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.

The specification that decides fit

The nozzle number KP23-50F and its compatibility with models K1722-2, K1802-1, K2286-1 and the K470, K471, K479, K541 and K575 series determine whether this is the correct replacement part for the specific gun in use.

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.
