18NG - Weldcraft 18NG Teflon Nozzle Insulator for W-400 & WP-18SC TIG Torches (2-Pack)

Protect Your W-400 Torch with the Weldcraft 18NG Insulator

Maximize the lifespan and performance of your water-cooled TIG torch with the Weldcraft 18NG Nozzle Insulator. Designed for the rigorous demands of the W-400 and WP-18SC series torches, this Teflon gasket is an essential consumable for professional fabricators. The W-400 series is known for its high-amperage capacity, often used in heavy industrial fabrication where heat management is critical. The 18NG insulator plays a vital role in this system by isolating the ceramic cup from the conductive torch head, preventing short circuits and ensuring the welding arc remains focused and stable.

Constructed from durable PTFE (Teflon), the 18NG is built to withstand the thermal cycling and high-frequency starts associated with TIG welding. Unlike inferior materials that may crack or degrade quickly under heat, this genuine Weldcraft part maintains its shape and insulating properties, providing a secure fit for your nozzles. It is specifically designed for standard setups using collet bodies, making it a staple for welders who rely on the W-400 for precision work on thick materials.

Maintenance of your TIG torch is key to consistent results. A damaged or carbon-fouled insulator can lead to erratic arcs, gas turbulence, and potential damage to the torch threads. By keeping a pack of 18NG insulators in your toolkit, you ensure that you can quickly address wear and tear without downtime. This 2-pack offers excellent value and ensures you are always prepared for the demands of the job site or workshop.
