CK PC-4S Back Purge Shield

Protect the weld as it cools—reduce oxidation and improve weld quality.
The CK-PC-4S Premium Purge shield is designed to provide secondary inert gas coverage during TIG welding applications involving reactive and exotic metals such as Titanium and Inconel®. By shielding the cooling weld bead and surrounding heat-affected zone, it helps prevent oxidation and contamination that can compromise weld quality.

Built for professional welding applications, the rectangular 4" design delivers broad gas coverage for improved protection and cleaner weld appearance.

Frequently Asked Questions

What does a purge cup do?
It extends inert gas coverage behind the torch to protect the weld as it cools.

Why is this important for Titanium and Inconel®?
These metals are highly sensitive to oxygen contamination at elevated temperatures.

Does this include the gas hose?
Yes. A 12.5' (3.8M) argon hose is included.

Can this improve weld appearance?
Yes. Proper shielding helps reduce oxidation and discoloration for cleaner-looking welds.
