Latest Patents

Paul B. Crilly holds a patent for a "Microprocessor based arc-air and welder noise abatement controller." This invention focuses on mitigating the sudden noise produced by abrupt changes in arc current. The technology employs a sensor to detect significant decreases in current during the initial stages of arc quench. It actuates circuits to maintain ionization and current flow, thereby avoiding the sharp final drop that results in a loud noise impulse. The system can maintain ionization by supplying RF energy at an appropriate frequency to the arc electrodes or by increasing the arc voltage. The sophisticated control algorithm is implemented using an inexpensive microprocessor, which effectively manages the arc sustaining parameters to reduce arc quenching impulse noise.
