The Weldcraft 50C40 Chuck is a critical consumable designed specifically for the high-precision demands of micro TIG welding. Engineered to fit the Weldcraft MT-125, WP-50, and WP-50V series torches, this chuck serves the function of a collet, securely gripping 0.040-inch (1.0mm) tungsten electrodes. In micro-welding applications—such as aerospace component repair, tool and die maintenance, or intricate electronics fabrication—arc stability is paramount. A worn or ill-fitting chuck can lead to tungsten slippage, poor electrical contact, and erratic arc wandering, all of which compromise the integrity of delicate welds.
Manufactured to Miller Weldcraft's exacting standards, the 50C40 ensures optimal current transfer from the torch body to the electrode. The component is crafted from high-quality conductive alloy, offering resistance to heat deformation even during prolonged use. Unlike standard collets used in larger torches, the "chuck" design in these micro torches is specialized to accommodate the compact head assembly while maintaining sufficient clamping force on fine-diameter tungsten.
This product is supplied as a package of two, allowing professional welders to keep a spare on hand for immediate replacement. Regular inspection and replacement of the chuck are recommended to maintain the precision performance expected from the MT-125 and WP-50 series torches. Whether you are welding thin-gauge aluminum, stainless steel, or exotic alloys, starting with a secure electrode connection is the first step toward a defect-free weld.
