Product DescriptionCK PC-4S Purge Cup4.0" (10.2 cm)12.5' Argon Hose IncludedWhen welding with metals such as Titanium, a secondary inert shielding gas application is necessary to protect the cooling weld bead and heat-affected zone.Trailing cups prevent oxidation by shielding the weld from the atmosphere until it has cooled to a safe temperature.
CK Purge Cup PC-4S includes a 12.5' hosePurge Cup PC-4S, 4" Diameter. Purging equipment for the backside of the weld on Ti & NiCrMo3 and Stainless Steel can be expensive. CK Purge Cups are portable and designed to maximize flow and diffuse high purity Argon minimizing oxidation (ugly blue color) on the backside of the weld. They are also great for purge enclosures to lessen mixing of atmospheric gases and reduce purge times.
