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

Miller Weldcraft 13N21L TIG Collet for Gas Lens Setups

Upgrade your TIG welding torch performance with the Miller Weldcraft 13N21L Gas Lens Collet, designed for 0.040" (1.0mm) tungsten electrodes. This essential consumable is compatible with the widely used WP-9, WP-20, WP-20P, and WP-25 series TIG torches. It is specifically engineered to function within a gas lens assembly, distinguishing it from standard collets used with conventional collet bodies. The primary role of this collet is to securely grip the tungsten electrode and transfer welding current efficiently, ensuring a stable and focused arc for precision work.

The use of a gas lens system, supported by the 13N21L collet, offers significant advantages for professional welders. Gas lenses replace the standard collet body with a multi-screen barrier that straightens the flow of shielding gas. This laminar flow reduces atmospheric contamination and allows the welder to extend the tungsten electrode further out from the nozzle—sometimes up to an inch—without losing gas coverage. This capability is invaluable for welding inside corners, pipes, or other hard-to-reach areas where visibility and access are limited. The 13N21L collet is the internal mechanism that makes this setup possible for .040" electrodes.

Durability and precision are hallmarks of the Weldcraft brand. These collets are crafted from premium copper alloys designed to withstand the high thermal cycles inherent in TIG welding. A compromised or twisted collet can restrict gas flow or fail to hold the tungsten, leading to arc wandering and frustration. By choosing genuine Weldcraft parts, you ensure a perfect fit and reliable performance. This package contains two collets, ensuring you have a backup ready when you need it most.

Installation is straightforward: simply insert the 13N21L collet into your gas lens collet body, insert your 0.040" tungsten, and tighten the back cap. This simple component plays a vital role in achieving the clean, high-quality welds that TIG welding is known for. Trust in Weldcraft's legacy of quality to keep your torch running smoothly and your welds defect-free.
