54N01 - 54N01 Gas Lens Insulator for 17, 18, 26 Series TIG Torches

Reliable Insulation for Precision TIG Welding

The ESAB 54N01 Gas Lens Insulator is a fundamental component for welders looking to utilize gas lens setups on their 17, 18, or 26 series TIG torches. Unlike standard collet body insulators, this specific heat shield is designed to accommodate the larger diameter of gas lens collet bodies, ensuring a secure fit and proper electrical isolation. By preventing the high-frequency current from arcing to the nozzle or cup, it protects both the torch head and the consumable assembly during operation.

Manufactured to strict tolerances, this insulator serves as the interface between the torch handle and the gas lens cup (alumina nozzle). It is crafted from durable, heat-resistant materials capable of withstanding the intense thermal cycles associated with TIG welding. Whether you are welding stainless steel, aluminum, or mild steel, maintaining the integrity of your torch's insulation is key to consistent arc stability and safety.

This part is universally compatible with the "3 Series" of TIG torches, which includes the popular air-cooled WP-17 and WP-26 models, as well as the water-cooled WP-18. It is an essential spare part for any fabricator's kit, allowing for quick changeovers between standard and gas lens configurations. Proper installation ensures that shielding gas is directed efficiently through the lens mesh, providing the laminar flow necessary for high-quality, contamination-free welds.
