The collet body improves gas coverage by creating a smoother gas flow, minimizing turbulence, and enhancing weld quality. The gas lens design ensures better shielding of the weld pool, reducing oxidation and resulting in cleaner, more controlled welds. Ideal for working with stainless steel, aluminum, and other sensitive metals, this collet body is perfect for high-quality, intricate welding tasks, providing superior performance and extended torch life.
