OVERVIEW

Reliable Performance with Weldcraft 10N50 TIG Cups

When you are under the hood, the last thing you want to worry about is your consumables failing mid-weld. The Weldcraft 10N50 Alumina Nozzle is the industry standard for a reason—it delivers consistent performance that professional welders trust. Whether you are running a water-cooled rig in a fabrication shop or an air-cooled torch in the field, these size #4 cups provide the durability and precision you need to lay down high-quality beads.

The #4 cup size (1/4 inch) is perfect for those tight spots where a larger nozzle just won't fit. It concentrates your shielding gas directly over the tungsten, allowing for excellent coverage even at lower flow rates. This makes it ideal for intricate work on thinner materials or root passes where precision is paramount. Made from tough alumina ceramic, these nozzles stand up to the intense heat of the TIG arc and resist cracking from rapid temperature changes. They also resist splatter adhesion, keeping your gas flow smooth and turbulence-free for that perfect stack of dimes.

We know that consumables are a recurring cost for any welder, which is why this genuine Weldcraft product comes in a convenient pack of 10. Having a fresh box of cups in your toolbox means you are never left scrambling when a cup inevitably gets dropped or reaches the end of its life. These nozzles thread on smoothly to your 17, 18, or 26 series torch, replacing worn-out parts in seconds so you can get back to burning metal. Don't settle for generic knock-offs that crumble under pressure; stick with Weldcraft for proven reliability.

Why Welders Choose This Pack:

  • Perfect Fit: Threads perfectly onto your standard collet body every time.
  • Tough Build: Handles the heat without cracking easily.
  • Precision Control: The #4 size gives you a tight gas column for detailed work.
  • Value: The 10-pack ensures you are stocked up for the long haul.
