3GHSLD - CK Worldwide 3GHSLD Large Diameter Gas Lens Insulator (2-Pack)

CK Worldwide 3GHSLD Heat Shield for Large Diameter Gas Lenses

The CK Worldwide 3GHSLD is a specialized heat shield insulator designed to facilitate the use of Large Diameter Gas Lenses on 3 Series TIG torches. When welders upgrade their standard torch setup to a large diameter gas lens configuration, the geometry of the front-end consumables changes significantly. The standard heat shield used with conventional collet bodies or standard gas lenses is often too small or shaped incorrectly to accommodate the wider base of the large diameter lens. The 3GHSLD bridges this gap, providing the necessary interface between the torch body and the specialized gas lens collet body.

This product is sold in a package of two, ensuring that professional fabricators always have a spare on hand during critical welding operations. The heat shield is manufactured from high-quality, heat-resistant materials capable of withstanding the intense thermal cycles associated with TIG welding. It acts as a thermal barrier, protecting the brass or silicone rubber of the torch head from the radiant heat of the arc and the conductive heat of the cup. Furthermore, it serves as a gas gasket, ensuring that the shielding gas flows correctly through the lens without leaking at the back of the cup, which is vital for maintaining the laminar flow that gas lenses are famous for.

Compatibility is a key strength of the CK 3GHSLD. It is engineered to fit the industry-standard "3 Series" torches. This includes a wide array of models such as the air-cooled 17 and 26 series, as well as the water-cooled 18 series. It also fits CK Worldwide's proprietary models like the CK150, CK210, CK300, CK510, and Trimline torches. Whether you are using a torch from Weldcraft, Lincoln Electric, WeldTec, or Profax, if it adheres to the 3 Series standard, this heat shield is the correct part for your large diameter gas lens conversion.

Using a large diameter gas lens is highly recommended for applications requiring superior gas coverage, such as welding stainless steel, titanium, or other reactive alloys. The large lens creates a broad, coherent stream of shielding gas that allows for greater tungsten stick-out, improving visibility in tight corners. The 3GHSLD is the foundational component that makes this high-performance setup possible on your existing torch body.
