OVERVIEW

Reliable 5/32" Collets for Everyday TIG Welding

Keep your TIG torch running smoothly with this 5-pack of 54N20 5/32" (4.0mm) Collets. Every welder knows that consumables are the lifeline of their equipment, and the collet is one of the most critical small parts in your torch. It’s responsible for holding your tungsten electrode firmly in place and transferring the welding current to the arc. When a collet gets worn out, twisted, or burnt, your arc stability suffers, and your welds can become inconsistent. Don't let a small part hold up a big job—keep fresh collets on hand to ensure you are always ready to lay down perfect beads.

These collets are designed to fit the most popular TIG torches in the industry: the 17, 18, and 26 series. Whether you are using a heavy-duty water-cooled WP-18 for thick plate or a versatile air-cooled WP-17 for shop fabrication, these collets drop right in. They are built to standard specifications, making them a perfect, cost-effective replacement for name-brand parts like Weldcraft. The 5/32" size is ideal for higher amperage applications where a thicker tungsten is required to handle the heat.

Buying in a pack of five means you save money and time. Instead of scrambling for a replacement when you accidentally overheat a collet or strip a thread, you'll have spares right in your toolbox. These generic replacements offer the same fit and function as the big brands but at a price that makes sense for the working welder. Upgrade your consumables inventory today and experience the difference a fresh, tight-gripping collet makes in your arc control.

FAQ

The 54N20 collet fits all 17, 18, and 26 series TIG torches, including air-cooled and water-cooled models from major brands like Weldcraft, Miller, Lincoln, and CK Worldwide.

This collet is designed specifically for 5/32-inch (4.0mm) diameter tungsten electrodes.

This product is sold as a pack of 5 collets.

Yes, you must use a collet body that matches the 17/18/26 series. While the collet itself is 54N20, it is typically paired with a standard collet body or a gas lens designed for 5/32" tungsten.

You should replace the collet if it becomes twisted, burnt, discolored, or if it no longer holds the tungsten electrode firmly. A damaged collet can cause poor arc starts and overheating.

This is a high-quality generic replacement part that meets or exceeds the specifications of the original Weldcraft 54N20 collet.

Yes, the collet is a mechanical holder and electrical contact point, so it works for both AC (aluminum/magnesium) and DC (steel/stainless) welding processes.
