18CG - Weldcraft 18CG TIG Torch Nozzle Insulator / Heat Shield (2-Pack)

Genuine Weldcraft 18CG Nozzle Insulator for TIG Welding

The Weldcraft 18CG Nozzle Insulator is a fundamental component for maintaining the efficiency and safety of your TIG welding setup. Designed specifically for the widely used 3-Series torches, this insulator fits 17, 18, and 26 series models, including both air-cooled and water-cooled configurations. As a genuine Miller Weldcraft product, it is manufactured to meet strict quality standards, ensuring a perfect seal and reliable performance during demanding welding operations.

This insulator, often referred to as a heat shield or gasket, serves a dual purpose. First, it provides necessary electrical insulation between the gas nozzle (cup) and the torch body, preventing potential short circuits or arcing that could damage the equipment or ruin the workpiece. Second, it acts as a thermal barrier, helping to dissipate heat and protect the torch head from the intense temperatures generated near the arc. This thermal protection is vital for extending the lifespan of your torch body and ensuring consistent gas flow.

Sold in a convenient package of two, the 18CG insulator ensures that professional welders and fabricators always have a spare on hand. TIG consumables are subject to wear and tear over time due to thermal cycling; replacing the insulator regularly helps maintain the structural integrity of the front-end torch assembly. Whether you are using a standard rigid torch or a flex-head model, the 18CG installs easily behind the collet body, seating firmly against the torch handle.

Josef Gas provides this essential consumable to support a wide range of industrial applications. By choosing genuine Weldcraft parts, you ensure compatibility with your existing Miller equipment as well as equivalent torches from other major manufacturers. Keep your TIG torch running cool and safe with high-quality insulators that resist cracking and heat deformation.
