13N28 - Generic 13N28 TIG Collet Body 3/32" (2.4mm) for 9/20 Series Torches

Optimize Your Arc with the 13N28 3/32" Collet Body

For TIG welders who demand consistency and precision, the 13N28 Collet Body is a fundamental component of your torch setup. Specifically sized for 3/32-inch (2.4mm) tungsten electrodes, this part plays a dual role: it compresses the collet to grip the tungsten firmly and acts as the conduit for the welding current. A worn or poor-quality collet body can lead to arc instability, overheating, and poor gas coverage, which is why using a reliable replacement like this Generic 13N28 is crucial for maintaining weld quality.

This collet body is designed to fit the "small series" torches, including the 9 series (air-cooled) and the 20 and 25 series (water-cooled). If you are using a WP-9 for intricate work on thin gauge materials or a WP-20 for higher amperage runs on aluminum or stainless steel, this 13N28 body is the correct match for your 3/32" setup. Its standard design works seamlessly with standard alumina cups, providing a straightforward and robust front-end assembly that is easy to change out and maintain.

One of the practical benefits of the standard collet body design over a gas lens is its slimmer profile. When you need to get into a tight corner or a narrow pipe gap, the 13N28 allows for a smaller cup size compared to bulky gas lens setups. The copper alloy construction ensures excellent conductivity, minimizing resistance heating within the torch head. This means your torch runs cooler, and your consumables last longer. The threads are machined to tight tolerances to ensure a smooth engagement with the torch head and the back cap, preventing gas leaks that could contaminate your weld pool.

To get the best performance, always ensure your collet body is free of spatter and that the threads are clean. If you notice the tungsten slipping or the arc wandering, it may be time to swap out your collet body. This generic replacement offers the durability you need for daily fabrication tasks without the premium price tag, allowing you to keep fresh consumables in your kit for whenever you need them. Whether you are welding mild steel, stainless, or exotic alloys, starting with a solid electrical connection at the collet body is the first step toward a perfect bead.
