A device to weld or splice two ends of a thermoplastic yarn. The device includes means for holding the yarn adjacent a heating element. The heating element is energized and the two ends of the yarn are fused together to form a globule of molten plastic. Thereafter, the heat is terminated and the device automatically pulls the two lengths of yarn apart and holds them under tension, and at the same time, the device molds the globule into a relatively smooth mass that has a width substantially equal to the width or diameter of the yarn.
