Title: Innovations by Zach MacMullen in Welding Technology
Introduction
Zach MacMullen is an accomplished inventor based in Larsen, Wisconsin. He has made significant contributions to the field of welding technology, holding a total of 5 patents. His work focuses on improving welding processes, particularly in controlling arc initiation and termination.
Latest Patents
One of Zach's latest patents is titled "Systems and methods for controlling arc initiation and termination in a welding process." This invention discloses systems and methods for initiating and/or terminating a GMAW-P welding process. The welding-type power supply includes power conversion circuitry that converts input power to welding-type power. A controller is designed to manage the power conversion circuitry based on various operating parameters. The systems implement pulsed cycles with increased output parameters to jump-start a pulsed welding cycle at a cold start, preventing a ball from forming on the end of the electrode wire during the welding process.
Another notable patent is "Systems and methods for voltage control of a short circuit during a pulse welding process." This invention addresses the issue of clearing a short during a GMAW-P welding process. The power supply includes similar power conversion circuitry and a controller that adjusts the output current to achieve target voltage values during a short circuit. Once the short is cleared, the controller adjusts the output current to return to a background voltage level.
