KP52065-1 - Lincoln Electric 1/8" (3.2mm) TIG Collet - KP52065-1

Keep Your Arc Smooth and Steady

Every TIG welder knows that the devil is in the details, and often, the smallest parts make the biggest difference. The Lincoln Electric KP52065-1 1/8" Collet is the unsung hero of your TIG torch setup. If you are running 1/8-inch tungsten—a standard size for medium to heavy-duty aluminum or steel jobs—you need a collet that grips tight and conducts electricity without faltering. Worn-out collets are a major cause of erratic arcs, wandering puddles, and frustrating starts. If your tungsten is slipping or you are noticing the torch head getting unusually hot, it is likely time to swap out your collet.

This genuine Lincoln part is built to take the heat. Made from robust copper alloy, it resists twisting and buckling better than cheap knock-offs. When you tighten down your back cap, this collet compresses evenly around the tungsten, ensuring a solid electrical connection. That connection is vital; a loose fit creates resistance, which creates heat, which eventually ruins your collet body and torch head. By using a fresh, high-quality collet like the KP52065-1, you ensure that the power from your machine goes exactly where it belongs: into the weld.

Installation is straightforward and quick, getting you back under the hood in seconds. Simply slide it into the collet body, insert your 1/8" tungsten, and tighten the cap. It is designed to fit perfectly with compatible Lincoln Electric TIG torches, eliminating the guesswork of matching parts. Whether you are walking the cup on pipe or laying dimes on a custom fabrication project, trust Lincoln Electric consumables to keep your equipment running as smoothly as your hand.

Why Replace Your Collets?

• Better Arc Starts: Good contact means instant ignition.
• Cooler Running Torch: Efficient power transfer reduces wasted heat in the handle.
• Secure Tungsten: No more tungsten dropping out in the middle of a critical pass.
