Weldcraft MT-125 90-Degree Collet Chuck 0.040"

Get Into the Tightest Spots

If you are running a Micro TIG setup like the MT-125, you already know that the job isn't about laying down pounds of filler metal—it's about precision, finesse, and often, getting into places where your hand barely fits. The Weldcraft 125C40-90 90-Degree Chuck is the accessory that saves the day when a straight shot just isn't possible. Whether you are welding inside a small manifold, repairing a delicate sensor housing, or working on intricate jewelry, this chuck angles your tungsten at a sharp 90 degrees, giving you the clearance you need to see the puddle and make the weld.

This specific chuck is sized for 0.040-inch (1.0mm) tungsten, which is a standard size for fine detail work. It holds the electrode rock-steady, so you don't have to worry about the tungsten slipping or the arc wandering when you are in the middle of a critical pass. Because it is a genuine Weldcraft part, it threads in perfectly and plays nice with the rest of your MT-125 torch parts. You won't be fighting with cross-threading or loose connections.

We know that micro-welding requires a steady hand and the right tools. Trying to force a straight torch into a 90-degree corner usually ends in frustration and a contaminated weld. By swapping in this 90-degree chuck, you convert your torch into a tool that can reach around corners. It is a small part that makes a massive difference in what you can fabricate or repair.

Don't get stuck on a job because you can't reach the joint. Keep a 125C40-90 in your kit so you are ready for those awkward angles. It’s built tough, conducts current smoothly, and helps you produce those stack-of-dimes welds even in the most impossible locations.
