12601261 - Tweco HD26-75 Heavy Duty MIG Nozzle 3/4 Inch Bore (2-Pack)

Maximize Your Arc Time with Tweco Heavy Duty Nozzles

When you are burning wire at high amps, your front-end consumables take a beating. The Tweco HD26-75 Heavy Duty Nozzle is built to take that heat and keep you welding. Designed for the professional welder who demands reliability, this nozzle features a rugged copper construction that resists melting and deformation even during prolonged spray transfer welding. If you are running a Tweco No. 6 or a similar heavy-duty gun, this is the nozzle that ensures your shielding gas gets exactly where it needs to be—covering the puddle completely.

The 3/4-inch (0.750") bore is a game-changer for heavy plate welding. A larger bore allows for a wider gas envelope, which is crucial when you are weaving or laying down large beads. It gives you better visibility of the contact tip and the weld pool, allowing for more precise gun manipulation. Unlike standard duty nozzles that might overheat and accumulate spatter rapidly, the heavy-duty walls of the HD26-75 dissipate heat efficiently, keeping the nozzle cooler and making spatter easier to remove. This means less time banging your gun against the table and more time laying beads.

This package includes two nozzles, giving you a backup right when you need it. We all know that moment when a nozzle gets bridged with spatter or crushed on a job site; having a fresh Tweco HD26-75 in your toolbox means you are back up and running in seconds. The slip-on fit is snug yet easy to remove, making tip changes and diffuser cleaning a breeze. Whether you are fabricating structural steel, repairing heavy machinery, or working in a shipyard, these nozzles provide the consistency and durability you expect from the Tweco brand.

Don't let poor gas coverage ruin your welds. Porosity is a welder's worst enemy, and it often starts with a damaged or undersized nozzle. By upgrading to the HD26-75, you ensure a smooth, laminar flow of gas that protects your work. Pair these with a good nozzle dip or anti-spatter spray, and you will find they last significantly longer than generic alternatives. Invest in genuine Tweco parts to keep your equipment running at peak performance.
