Abstract: An improved electrode and electrode working tip for a gas tungsten arc welding apparatus. The face of the working tip of the electrode is formed as a narrow ring coaxial with the electrode and having an area less than the area of electron emission for the operating currents of the electrode. The reduced area of the narrow annular ring forces the area of electron emission to spread to the immediately adjacent walls. The improved electrode working tip provides a more stable and uniform plasma of reduced diameter for improved precision and repeatability in welds which is the ability to consistently reproduce welding parameters. The electrode tip also has a significantly increased working life.
