12301075 - Tweco 23-50 MIG Gun Nozzle, 1/2" Bore, Thread-On (1230-1075)

Reliable Replacement: Tweco 23-50 MIG Nozzle

Keep your MIG gun running smoothly with the Tweco 23-50 Nozzle (1230-1075). If you are running a Tweco Spray Master or a classic Tweco Professional series gun (like the No. 2, 3, or 4), this is likely the standard nozzle you reach for every day. Featuring a 1/2-inch bore, this nozzle is the "goldilocks" size for most welding jobs—small enough to get into tighter corners but wide enough to provide excellent gas coverage for solid welds. Whether you are welding mild steel in the shop or doing repairs in the field, this nozzle delivers consistent performance.

The thread-on design is a favorite among welders because it stays put. Unlike slip-on nozzles that can loosen up over time or get knocked out of alignment, the 23-50 screws on tight and stays centered. This means your contact tip stays right where it needs to be, and your shielding gas flows evenly around the puddle. No more worrying about the nozzle falling off when you are cleaning out spatter or maneuvering around a jig. Plus, the solid copper construction handles the heat of high-amperage welding without melting or deforming easily.

Replacing your nozzle regularly is key to preventing porosity and maintaining a clean arc. A worn-out nozzle with spatter buildup can disrupt gas flow and ruin your weld. The Tweco 23-50 is built tough to last, but when it's time for a fresh one, this genuine Tweco part ensures you are back up and running in seconds. It fits perfectly over your standard Tweco insulators, making change-outs quick and hassle-free. Stock up on these essentials so you never have to stop a job because of a bad nozzle.
