13N13 - Weldcraft 13N13 #10 Alumina Cup for 9/20 Torches (10-Pack)

Reliable Gas Coverage with Weldcraft 13N13 #10 Cups

Every TIG welder knows that gas coverage is king. When you are laying down beads on stainless steel or trying to keep an aluminum puddle clean, the size of your cup matters. The Weldcraft 13N13 is a #10 Alumina Nozzle, giving you a generous 5/8-inch opening. This larger diameter is perfect for those times when you need a wider gas envelope to protect the heat-affected zone from atmospheric contamination. It also allows you to stick your tungsten out a bit further to see around tricky corners while still keeping the puddle bathed in argon.

These nozzles are built for the daily grind. Made from durable alumina ceramic, they resist the thermal shock of rapid heating and cooling that happens every time you strike an arc and terminate a weld. They are designed to fit the industry-standard 9 series (air-cooled) and 20 series (water-cooled) torches. If you are running a Miller Diamondback, a Weldcraft WP-20, or any compatible setup using standard collet bodies, these cups will screw right on without a fight. No gritty threads or loose fits here—just genuine Weldcraft quality.

We sell these in a pack of 10 because we know how it goes in the shop. You drop a torch, you bump a clamp, or you just weld enough amperage that the cup eventually gets cooked. Having a 10-pack in your toolbox means you aren't stopping the job to hunt for a spare. You just grab a fresh 13N13, thread it on, and get back under the hood. The #10 size is a versatile addition to your kit, bridging the gap between standard #7 or #8 cups and the massive gas lenses used for specialty work.

Don't let poor gas coverage ruin your weld appearance or integrity. Upgrade your consumable stash with genuine Weldcraft 13N13 nozzles. They deliver the consistent flow and durability you need to produce stack-of-dimes welds shift after shift. Whether you are in the garage or on the production line, these cups are a staple for any serious TIG setup.
