50N04 - Weldcraft WP-50 Lava Cup #4 with Screen (10-Pack)

Get Into Tight Spots Without Melting Your Cup

When you are running a Micro TIG torch like the WP-50, you are usually in a tight spot. Maybe you are repairing a die, welding inside a small tube, or working on intricate aerospace parts. In these confined spaces, heat has nowhere to go but back at your torch. Standard ceramic cups can crack under this reflected heat, but the Weldcraft 50N04 Lava Nozzle is built to take it. The Lava material is tougher against thermal shock, meaning you spend less time replacing cracked cups and more time dropping dimes.

This isn't just a tough cup; it's a smart one. The 50N04 comes with built-in screens inside the #4 (1/4") orifice. These screens act like a diffuser, smoothing out your shielding gas flow. In micro-welding, a turbulent gas stream can ruin a tiny weld in a split second. The screens ensure a soft, laminar column of argon covers your tungsten and puddle, giving you the clarity and control you need for delicate work. It fits perfectly on your Weldcraft 50 or 50V torch.

This pack contains 10 nozzles, so you can stock up your toolbox or supply cabinet. Whether you are welding stainless, titanium, or aluminum in hard-to-reach places, having a nozzle that can handle the heat and deliver clean gas coverage is a game-changer. Upgrade your Micro TIG setup with the durability of Lava.
