84Z35 - ESAB 0.040" TIG Collet for HW-9/HW-20 Torches (2-Pack)

Reliable Grip for Fine TIG Work

When you are welding thin gauge materials that require the finesse of a 0.040-inch tungsten, your torch setup needs to be flawless. The ESAB 84Z35 Collet is the standard replacement part for holding that fine tungsten in place within your HW-9 or HW-20 TIG torch. Sold in a convenient pack of two, these collets are designed to keep you welding without interruption. We know that in the shop, a slipping tungsten or a sputtering arc can ruin a perfect bead, and often the culprit is a worn-out collet that has lost its shape or tension.

These collets are built from durable copper, designed to withstand the heat of the arc while maintaining a tight grip on the electrode. The split-design allows the collet to compress against the tungsten when the back cap is tightened, locking it firmly in the center of the gas cup. Because 0.040" tungsten is quite thin, it requires a collet with precise tolerances; if the collet is too loose, the tungsten will drop out, and if it's too tight or burred, it won't slide properly for adjustment. ESAB's manufacturing ensures that these collets meet the strict requirements needed for stable, low-amperage welding.

Compatible with the popular "small body" torches—including the air-cooled 9 series and the water-cooled 20 and 25 series—this part is a staple in many TIG kits. Whether you are working on stainless steel exhaust headers, aluminum intake piping, or intricate artistic metalwork, having a fresh collet ensures your current transfer is smooth and your arc starts are crisp. Worn collets can create resistance, heating up your torch unnecessarily and leading to inconsistent power at the puddle. Swapping out your collet is one of the cheapest and easiest ways to troubleshoot an unstable arc.

Don't let a five-dollar part cost you hours of rework. Keep a pack of ESAB 84Z35 collets in your toolbox so you are always ready for fine-detail applications. This 2-pack ensures you have a backup on hand, so if one gets twisted from overtightening or heat stress, you can swap it out in seconds and get back under the hood. Trust in ESAB quality to keep your torch running cool and your welds looking professional.
