The CK Worldwide 300HS Heatshield is a critical consumable component designed for Series 3 TIG welding torches. Industry-standardized as the 18CG, this heatshield serves as the interface between the torch body and the ceramic gas cup (nozzle). Its primary function is twofold: it provides necessary electrical insulation to prevent the welding current from arcing to the nozzle, and it creates a mechanical seal to ensure shielding gas is directed entirely through the cup without leaking at the threads.
Manufactured to CK Worldwide's exacting standards, the 300HS is compatible with a broad range of torches, including the widely used air-cooled 17 and 26 series, as well as the water-cooled 18 series. It also fits CK's proprietary CS300 and CS310 models. The component is crafted from a high-temperature composite material capable of withstanding the intense radiant heat generated during the GTAW process, resisting cracking and deformation better than standard generic insulators.
This product is supplied as a 2-pack, recognizing that heatshields are consumables that require periodic replacement. A compromised heatshield can lead to baffling weld defects, such as porosity caused by air entrainment (venturi effect) through hairline cracks. By maintaining a fresh seal with the CK 300HS, operators ensure consistent gas coverage and protect the longevity of their torch head threads. This item is an essential stock component for any MRO inventory supporting TIG welding operations.
