16K18 - ESAB 16K18 TIG Alumina Cup Size 9 (9/16")

Achieve Cleaner Welds with the ESAB #9 TIG Cup

When you are laying down critical beads, your gas coverage is everything. The ESAB 16K18 Alumina Nozzle #9 is built to give you the reliable shielding you need to keep your puddle clean and your arc stable. With a 9/16-inch opening, this size #9 cup provides a wide umbrella of shielding gas, making it an excellent choice when you need a bit more coverage than a standard #7 or #8 cup can offer. Whether you are walking the cup on pipe or performing intricate bench work, this nozzle helps ensure your weld zone stays protected from the atmosphere.

Durability is key in any shop, and this nozzle is made from tough alumina ceramic that can handle the heat. We all know that thermal shock can crack lesser cups, but the ESAB 16K18 is designed to resist cracking even when you are pushing high amps. The ceramic material also acts as an electrical insulator, preventing accidental arcing if you get a little too close to the workpiece in tight spots. It screws on or fits securely to your compatible torch, so you don't have to worry about it rattling loose in the middle of a pass.

Using the right consumables makes a huge difference in your day-to-day welding experience. A fresh, clean nozzle like the 16K18 ensures that your gas flow is smooth and laminar, not turbulent. Turbulent gas can pull in air and ruin a perfect weld with porosity. By upgrading to high-quality ESAB consumables, you are investing in consistency. Keep a few of these #9 cups in your kit so you are always ready to tackle joints that require that extra bit of gas coverage and visibility.
