The invention describes a method of manufacturing a color cathode-ray tube having a color selection electrode attached to a plurality of support studs distributed about and affixed to an interior surface portion of a faceplate panel. The manufacturing steps include: attaching a plurality of support means, each of which includes stud-engaging means, and at least one of the stud-engaging means comprising a washer having a stud-receiving aperture therethrough, to the color selection electrode; positioning the color selection electrode within the faceplate panel with the stud-engaging means positioned on the support studs; and, then, welding the washer to the support means. The method is improved over the prior method, which utilized a mechanical shield for preventing weld-generated debris from contacting the faceplate panel and/or the color selection electrode, by directing a stream of air, during the welding step, between the faceplate panel and the color selection electrode toward the stud having the washer thereon sufficient to direct the weld-generated debris away from the faceplate panel.
