  • Patent number: 9662736
    Abstract: The invention described herein generally pertains to a system and method for generating a negative polarity welding output current waveform to control a welding process. An electric arc welding system generates an electric welding waveform with portions in a negative polarity. A cycle of the electric welding waveform includes a background current phase, a short clearing ramp phase after the background current phase, a peak current phase, and a tail-out current phase of the electric welding waveform, wherein the peak current phase provides a negative peak current level, the tail-out current phase provides a monotonically increasing tail-out current level toward the positive background current level, and the short clearing ramp phase provides a decreasing current level in a positive polarity of current for the electric welding waveform.

  • Patent number: 8054154
    Abstract: A planar transformer includes first and second windings that may be comprised of electrically conductive traces etched onto one or more printed circuit boards. The printed circuit boards may be arranged in various orientations so as to change the turns ratio of the planar transformer. In one embodiment, the printed circuit boards are substantially similar and may be electrically connected via connectors that separate the circuit boards. Insulating sleeves may be inserted between the printed circuit boards in an interleaved configuration.

  • Patent number: 6998574
    Abstract: An electric arc welding torch having a central conductive contact tube for electrical contact between a power source and a welding wire moving through the contact tube toward a workpiece, a conductive sleeve concentric with the tube to define an annular chamber between the tube and the sleeve, a first dielectric barrier sleeve fixed on the conductive sleeve and a second dielectric sleeve on the tube where the dielectric sleeves are spaced from each other to define an annular gas passage extending around the moving wire and terminals to connect a high frequency power source between the tube and the conductive sleeve to create a dielectric barrier discharge plasma issuing from the gas passage. This torch is used in a novel welding method where the shielding gas envelope around the arc is a plasma.
