13N21 - Weldcraft 13N21 TIG Collet .040" (5-Pack)

Reliable Arc Starts with Weldcraft 13N21 Collets

Every TIG welder knows that the quality of the arc starts with the connection inside the torch. The Weldcraft 13N21 Collet is the unsung hero of your 9 or 20 series torch setup when you are working with fine .040" (1.0mm) tungsten. Whether you are welding delicate aluminum sheets or thin stainless steel tubing, having a fresh, high-quality collet is the difference between a crisp, focused arc and a frustrating day of wandering puddles and sputtering starts.

Over time, collets can twist, deform, or accumulate oxidation, leading to poor electrical contact. When your collet fails to grip the tungsten tightly, you lose current transfer efficiency, which causes the collet itself to heat up rapidly. This heat can fuse the collet to the collet body or the tungsten, ruining your consumables and potentially damaging your torch head. By swapping in a fresh Weldcraft 13N21, you ensure a solid mechanical grip and optimal conductivity. These collets are made from premium copper alloy that resists deformation better than cheap generic alternatives, giving you longer service life and more consistent performance.

This 5-pack is an essential addition to your welding kit. Since .040" tungsten is often used for low-amperage, high-precision work, any instability in the arc is immediately noticeable. Don't let a worn-out $2 part ruin a critical weld on an expensive manifold or aerospace component. These collets fit perfectly in your WP-9, WP-20, or WP-25 torch, working seamlessly with your existing back caps and collet bodies. Keep your consumables fresh and your welds clean with genuine Weldcraft reliability.
