10N47 - 10N47 Alumina Cup #7 for WP-17/18/26 TIG Torches

Reliable #7 TIG Cup for Everyday Welding

Every TIG welder knows the frustration of dropping a torch and hearing that distinct *crack* of a ceramic cup hitting the concrete. The Generic 10N47 Alumina Nozzle Cup is your go-to replacement for the standard #7 cup, arguably the most versatile size in your welding arsenal. Whether you are running a rig in a fabrication shop, fixing exhaust pipes in an automotive garage, or working on a hobby project at home, this cup is designed to get you back under the hood fast without breaking the bank.

This nozzle fits the most common TIG torches in the industry: the air-cooled 17 and 26 series, and the water-cooled 18 series. If you are using a standard collet body setup (the kind that comes stock with most machines), this is the part you need. The #7 size (7/16") is the "Goldilocks" of TIG cups—it's not so wide that it gets in the way of seeing the puddle, but it's wide enough to provide excellent gas coverage for most tungsten stick-outs. It's perfect for walking the cup on pipe or free-handing intricate joints.

Why choose this generic replacement?

Welding consumables are an operating cost that adds up. This nozzle offers the same heat resistance and durability as the big-name brands but at a price point that makes sense for high-volume shops. The pink alumina ceramic stands up to high amperage heat and resists splatter buildup, meaning you spend less time cleaning your torch and more time laying beads. It threads on smoothly and seats firmly against the insulator gasket, ensuring you don't waste expensive argon through leaks.

Don't let a broken cup stop your production. These nozzles are designed to be swapped out in seconds. Simply unscrew the old one, check your collet body for tightness, and screw this new 10N47 cup in place. It works seamlessly with your existing 10N series collets and collet bodies. Whether you are welding mild steel, stainless, or aluminum, having a fresh, clean nozzle is the first step to a perfect weld. Keep a box of these in your toolbox so you are never left scrambling for parts when a job is due.
