18C36 - Weldcraft 18SC Series Heavy Duty Collet 3/16 Inch - 2 Pack

Heavy Duty Performance for 18SC Torches

When you are pushing high amps through an 18SC torch, you can't rely on standard consumables. The Miller Weldcraft 18C36 Heavy Duty Collet is built for the serious welder running 3/16-inch (4.8mm) tungsten. This isn't your average collet; it is designed specifically for the Super Cool (18SC) series, meaning it can handle the heat and the current required for heavy fabrication jobs. Whether you are welding thick aluminum plate or heavy-wall stainless pipe, this collet ensures your tungsten stays put and your arc stays smooth.

Built to Last

We know that downtime kills productivity. That is why these collets are made from durable copper alloy that resists twisting and buckling under heat. A cheap collet can overheat, deform, and ruin your gas flow or, worse, fuse to your tungsten. The 18C36 is engineered to maximize contact area with the electrode, ensuring efficient power transfer. This keeps the collet cooler and extends the life of your consumables. When you are running at 300 or 400 amps, that extra durability makes all the difference between a clean run and a mid-weld failure.

The Right Fit for the Job

Precision matters in TIG welding. This collet is machined to exact tolerances to grip 3/16" tungsten firmly without slipping. A loose tungsten leads to wandering arcs and contamination, while a collet that is too tight can snap your electrode during setup. The 18C36 hits the sweet spot, giving you reliable grip and easy adjustment. Because it is designed for the 18SC, it fits perfectly inside the heavy-duty collet body, ensuring proper gas coverage and cooling efficiency.

Stock Up and Stay Ready

This product comes as a convenient 2-pack. Every experienced TIG welder knows that collets are consumables that eventually wear out. Having a spare in your kit means you aren't stuck waiting on a delivery truck when you should be burning rod. If you are running an 18SC rig, these are the specific collets you need to keep your torch performing at its peak. Don't compromise your setup with mismatched parts; stick with genuine Weldcraft heavy-duty components for consistent results.
