WELDING WIRE FEEDER

摘要

PURPOSE:To decrease oscillation of a spool for a welding wire by cutting the upper part in the axial direction on the outside circumference of the spool which supports pivotally the shaft of the spool for the welding wire and supporting pivotally the spool for the welding wire in such a way that the inside circumference of the spool contacts the plural ridgelines of the spool shaft. CONSTITUTION:The upper part in the axial direction on the outside circumference of a spool shaft 13 is cut and the ridgeline passing the support points D, E viewed from the side face of a spool 5 for a welding wire is formed in the axial direction. The shaft 13 formed with the plural ridgelines is attached to a frame body and the spool for the welding wire is pivotally supported in such a way that the inside circumference of the spool 5 contacts the plural ridgelines of the shaft 13. The smooth rotation of the spool for the welding wire is thus made possible and the oscillation thereof is decreased.
