OVERVIEW

Maximize Gas Coverage with Tweco 25I-75 Nozzles

When you are pushing high amps and laying down heavy beads, your gas coverage can make or break the weld. The Tweco 25I-75 Slip-On Nozzle is built for welders who need reliable performance from their Tweco No. 5 MIG guns. With a wide 3/4-inch bore, this nozzle is a beast for high-heat applications. It provides a massive column of shielding gas, which is exactly what you need when you are running spray transfer or working with flux-cored wires that require auxiliary shielding. The wide opening helps ensure your weld pool stays protected from the atmosphere, keeping your welds clean and porosity-free.

We all know the frustration of a nozzle that gets stuck right when you need to clean it or change a tip. The 25I-75 features a slip-on design that makes maintenance a breeze. There are no threads to get crossed or fused by spatter. You simply slide it off the gas diffuser, clean out the spatter, and slide it back on. The internal insulation ensures a snug fit and protects the front end of your gun from electrical shorts. This pack of two ensures you always have a backup ready to go in your toolbox, so you aren't left searching for parts in the middle of a job.

Constructed from durable copper alloy, these nozzles stand up to the intense heat of heavy fabrication. Whether you are welding structural beams, heavy machinery, or thick plate, the Tweco 25I-75 gives you the visibility and gas flow control you need. It is the standard choice for professional welders running the classic Tweco #5 gun who demand consistent quality and ease of use. Don't let poor gas coverage ruin your work; upgrade to the 3/4" bore nozzle designed for the job.

FAQ

The Tweco 25I-75 is designed primarily for Tweco No. 5 MIG guns and other MIG guns that utilize the Tweco 25 Series consumables and 55 Series gas diffusers.

This nozzle has a 3/4-inch (0.750" or 19.05 mm) bore orifice, which is ideal for high-amperage applications requiring extensive gas coverage.

The 25I-75 is a slip-on nozzle. It relies on friction and the internal insulator to stay secured to the gas diffuser, allowing for easy removal.

This product (SKU 12501130) is a package containing 2 nozzles.

It is manufactured from a copper alloy, chosen for its high thermal conductivity and resistance to spatter adhesion.

A larger 3/4 inch bore is used for higher amperage welding where the weld pool is larger and hotter, requiring a broader flow of shielding gas to prevent contamination.

Yes, the 'I' in 25I-75 stands for Insulated. The nozzle comes with the necessary insulation material built into the slip-on connection point.

Yes, it is suitable for gas-shielded flux-cored welding (Dual Shield), especially given the large bore which helps maintain coverage over the aggressive arc.
