The Weldcraft 18GL36 Collet Body is a specialized gas lens component designed exclusively for the heavy-duty 18SC water-cooled TIG torch. When welding thick materials with 3/16" (4.8mm) tungsten, maintaining a stable shielding gas environment is critical to preventing defects. Unlike standard collet bodies that can create turbulent gas exit patterns, the 18GL36 utilizes advanced gas lens technology to rectify the flow of argon or helium into a smooth, laminar stream.
This laminar flow significantly improves the efficiency of your shielding gas. By reducing turbulence, the gas stream remains coherent for a greater distance from the nozzle face. This characteristic allows the welder to extend the tungsten electrode significantly beyond the cup—often necessary for reaching into fillets, V-grooves, or complex geometries—while still maintaining a pristine inert atmosphere around the molten pool. The result is a cleaner weld with reduced oxidation, less post-weld cleaning, and improved mechanical properties.
Manufactured to Weldcraft's exacting standards, the 18GL36 ensures perfect concentricity and electrical conductivity. It fits securely within the 18SC torch head, ensuring optimal current transfer to the tungsten electrode. This is vital for high-amperage applications where resistance heating at the collet interface can lead to premature failure. Sold in a convenient pack of two, these collet bodies are a smart investment for any fabrication shop running 18SC torches. Whether you are welding aluminum, stainless steel, or exotic alloys, the control provided by this gas lens system is indispensable for professional-grade results.
