22-10 - Weldcraft 22-10 Nozzle Insulator Gasket (2-Pack) for 22/23 Series Torches

High-Performance Electrical Isolation for TIG Torches

The Weldcraft 22-10 Nozzle Insulator is a critical consumable component designed specifically for the heavy-duty requirements of 22 and 23 Series TIG torches. In precision Gas Tungsten Arc Welding (GTAW), maintaining the integrity of the torch assembly is paramount for both safety and weld quality. This insulator serves a dual purpose: it acts as a dielectric barrier to electrically isolate the nozzle from the energized torch body, and it functions as a gasket to ensure a hermetic seal for the shielding gas.

Manufactured to Weldcraft's exacting OEM standards, the 22-10 insulator is constructed from durable, heat-resistant materials capable of withstanding the intense thermal cycling associated with water-cooled TIG welding applications. The 22 and 23 series torches are often utilized in automated or high-amperage handheld setups where heat generation is significant. A compromised insulator can lead to high-frequency leakage, arc instability, or even damage to the torch body itself. By utilizing genuine Weldcraft parts, operators ensure that the dimensional tolerances match perfectly with the collet body and nozzle cup, preventing gas turbulence that could lead to weld porosity.

This product is supplied as a pack of 2, recognizing that insulators are wear items that require periodic inspection and replacement. Over time, exposure to UV radiation, ozone, and thermal stress can cause insulators to become brittle or crack. Proactive maintenance using the 22-10 gasket ensures that the shielding gas flow remains laminar and directed entirely over the weld pool, rather than leaking at the nozzle threads. This attention to detail in the torch assembly contributes directly to the consistency and cleanliness of the final weld deposit.

Technical Specifications and Application

The 22-10 is engineered to fit seamlessly between the torch body and the gas nozzle (cup). It is compatible with standard alumina nozzles as well as specialty cups designed for the 22/23 series. Industrial MRO professionals rely on genuine Miller/Weldcraft components to maintain the validity of equipment warranties and to ensure that production downtime is minimized. Whether used in aerospace fabrication, pipe welding, or general industrial manufacturing, this insulator is a small but vital part of the welding system.
