Elliott Stava has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).
Abstract: An electric arc welding system for creating an AC welding arc between an electrode and a workpiece wherein the system comprises a first controller for a first power supply to cause the first power supply to create an AC current between the electrode and workpiece by generating a switch signal or command with polarity reversing switching points in the first controller, with the first controller operated at first welding parameters in response to first power supply specific parameter signals to the first controller. The system has at least one slave controller for operating a slave power supply to create an AC current between the electrode and workpiece by reversing polarity of the AC current at switching points where the slave controller is operated at second welding parameters in response to second power supply specific parameter signals to the slave controller.

Abstract: An electrode position detection system for a welder having a laser that is projected in a lateral plane to laterally cross a welding wire at a location below a contact tip of a welding gun and a receiver that receive the laser bean after crossing the welding wire, and a measuring device that determines one or more parameter of the welding wire based on the received laser beam. Arc voltage measurements can also be used to determine one or more parameter of the welding wire.
