12401237 - Tweco HD24-75F Heavy Duty MIG Nozzle, 3/4" Bore, Flush Tip (2-Pack)

Heavy-Duty Performance for Professional Welders

When you are pushing high amps and laying down serious beads, your MIG gun's front-end consumables take a beating. The Tweco HD24-75F Heavy Duty Nozzle is built to take the heat and keep you welding. Designed specifically for the industry-standard Tweco No. 4 and No. 5 MIG guns (as well as Spray Master 350/450 models), this nozzle is a workhorse for structural steel, heavy fabrication, and manufacturing applications. This package contains two nozzles, giving you a reliable backup right when you need it.

Optimal Gas Coverage & Visibility
The HD24-75F features a large 3/4-inch (19mm) bore. This wide opening is crucial when you are running hot, ensuring a broad umbrella of shielding gas protects your molten puddle from atmospheric contaminants. It is especially effective for spray transfer welding, where a stable gas column is key to preventing porosity. The "Flush" tip design means your contact tip sits even with the end of the nozzle. This setup is a favorite among many pros because it offers great visibility of the arc and puddle without sacrificing gas protection, allowing you to get into the groove and see exactly what you are doing.

Built to Last
Cheap nozzles deform and accumulate spatter that won't come off. Tweco's heavy-duty copper alloy construction resists spatter adhesion and dissipates heat quickly, keeping your front end cooler and lasting longer. Whether you are replacing worn-out parts or stocking up your tool crib, these genuine Tweco nozzles deliver the consistency and fit you expect from the brand that defined MIG welding. Keep your arc smooth and your welds clean with the HD24-75F.
