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

Maximize Arc Stability with Weldcraft 13N21 Collets

Achieving the perfect TIG weld requires more than just skill; it demands equipment that won't let you down. The Weldcraft 13N21 Collet is the standard choice for professional welders using .040" (1.0mm) tungsten electrodes. Whether you are using a compact air-cooled 9 series torch for tight spaces or a water-cooled 20 series for higher duty cycles, this collet delivers the grip and conductivity you need. TIG welding with small diameter tungsten requires precision, and the 13N21 ensures your electrode is held concentric to the gas lens or nozzle, providing a focused arc and optimal gas coverage.

Precision Grip for Fine Work

When welding thin materials like aluminum sheet or stainless steel tubing, arc control is everything. A worn or poorly made collet can allow the tungsten to slip or sit off-center, causing erratic arc behavior and potential contamination. Weldcraft's 13N21 collets are machined to exact specifications to provide a uniform clamping force around the tungsten when the back cap is tightened. This secure grip not only prevents slippage but also maximizes the surface area contact for current transfer, reducing resistance and heat buildup within the torch head.

The Weldcraft Advantage

Genuine Weldcraft parts are synonymous with quality in the welding industry. While generic consumables may look similar, they often lack the material consistency and dimensional accuracy of the OEM part. Using the 13N21 ensures that your torch threads are protected and that the collet deforms predictably to grip the tungsten without twisting permanently. This pack of 5 ensures you are ready for multiple tungsten changes or replacements, keeping you welding without interruption. Upgrade your consumables to Weldcraft and experience the difference in arc starting and stability.

Installation and Maintenance

To install, simply insert the 13N21 collet into the torch body (or gas lens), insert your .040" tungsten, and tighten the back cap. It is recommended to inspect your collets regularly. If you notice discoloration, twisting, or if the tungsten becomes difficult to insert, it is time to replace the collet to prevent damage to your torch head.
