Tweco 24A MIG Nozzle 0.625
The Tweco 358-1240-1221 is a replacement MIG welding nozzle manufactured from HAWA material. It is built for Spray Master 350 and Spray Master 450 guns using the 24A series consumable platform. The 0.625 inch bore directs shielding gas around the wire. Welders running these specific gun models use this nozzle to maintain consistent gas coverage.
Fits 24A Spray Master guns only
This nozzle suits operators maintaining Tweco Spray Master 350 or 450 equipment that accepts 24A series tips and nozzles. It will not fit guns built for other Tweco series or competitor consumable systems. Shops standardising on a different nozzle thread or bore diameter must select the matching part for their specific gun model.
0.625 inch bore diameter
The critical specification is the 0.625 inch internal diameter, marked as 62 in the supplier reference. This bore size determines the gas envelope around the electrode wire. Verify the gun manual calls for a 0.625 inch nozzle before ordering; a different bore will change gas flow dynamics and shielding effectiveness.
