13N21L - Weldcraft 13N21L .040" Gas Lens Collet (2-Pack)

Weldcraft 13N21L Gas Lens Collet .040" (1.0mm) - 2 Pack

The Weldcraft 13N21L Gas Lens Collet is a critical component for TIG welders utilizing gas lens setups on their torches. Specifically designed to hold 0.040-inch (1.0mm) tungsten electrodes securely, this collet ensures optimal electrical conductivity and mechanical stability during the welding process. It is engineered to fit a variety of popular TIG torch models, including the air-cooled WP-9 series and the water-cooled WP-20 and WP-25 series, as well as the CS310. By maintaining a precise grip on the tungsten, it allows for consistent arc starting and stability, which is essential for high-quality precision welding.

Unlike standard collets, this model is tailored for use with gas lens collet bodies. Gas lenses are favored in the industry for their ability to create a laminar flow of shielding gas, reducing turbulence and providing better coverage over the weld pool. This is particularly important when welding reactive metals or when extending the tungsten stick-out to reach into tight corners. The 13N21L collet works in harmony with the gas lens body to ensure that the gas flow remains undisturbed while firmly securing the electrode in the center of the gas stream.

Manufactured by Weldcraft (a Miller Electric brand), these collets are built to rigorous standards using high-grade copper alloy. This material choice ensures excellent heat resistance and durability, preventing deformation under the thermal stress of welding. Regular replacement of collets is necessary to maintain performance, as worn collets can lead to poor arc control or gas leakage. This product is sold in a pack of two, providing welders with a necessary spare to minimize downtime in the shop.

Whether you are performing intricate aerospace work or general fabrication, using genuine Weldcraft consumables like the 13N21L ensures that your equipment operates at its peak potential. The precise machining guarantees that the collet fits perfectly within the torch head, preventing issues such as tungsten slippage or overheating due to poor contact.
