OVERVIEW

Heavy-Duty Performance

When you are pushing high amps and laying down serious beads, you need a nozzle that can take the heat. The Tweco 24A-75 Adjustable MIG Nozzle is the industry standard for a reason. Built for the legendary Tweco #4 MIG guns, this nozzle features a wide 3/4-inch bore that ensures your weld pool stays fully protected by shielding gas, even during hot spray transfer welding. Don't let poor gas coverage ruin your welds—upgrade to the nozzle designed for the job.

Adjustable for Precision

Every welder knows that tip recess matters. Whether you need a deep recess for high heat or a flush fit for tight corners, the 24A-75's adjustable slip-on design gives you full control. Simply slide it over the insulator to your preferred position. No threads to seize up, just a secure friction fit that stays put until you move it. Made from durable copper, these nozzles resist spatter buildup and clean up easily, keeping you welding longer with less downtime.

Value Pack

This convenient Pack of 2 ensures you aren't left scrambling when a nozzle finally wears out. Keep a spare in your toolbox or on your cart. Genuine Tweco parts mean you get consistent dimensions and quality every time you open a package. Perfect for professional fabricators, pipe welders, and industrial maintenance teams looking for reliable arc performance.

FAQ

The Tweco 24A-75 nozzle has a 3/4-inch (19.1 mm) bore opening, which provides excellent gas coverage for high-amperage welding.

Yes, the 'A' in 24A-75 stands for Adjustable. It is a slip-on nozzle that allows you to vary the contact tip recess.

It is designed to fit Tweco No. 4 series MIG guns, including the Classic 4 and Spray Master 450, as well as other guns compatible with Tweco 24 Series consumables.

This product (SKU 1240-1734) is sold as a pack of 2 nozzles.

Yes, this nozzle typically requires a 34A (or compatible) nozzle insulator to electrically isolate it from the gas diffuser and to provide the friction fit.

The 24A-62 has a 5/8" bore, while the 24A-75 has a larger 3/4" bore. The 3/4" bore is better suited for higher amperages and spray transfer modes.

No, this is a slip-on style nozzle. It relies on the friction fit over the insulator, not threads.
