Title: Pierre Alfred Roulet: Innovator in Electric Arc Welding Technology.
Introduction
Pierre Alfred Roulet is a notable inventor based in São Paulo, Brazil. He has made significant contributions to the field of electric arc welding. His innovative approach has led to the development of a unique power supply system that enhances safety and efficiency in welding operations.
Latest Patents
Roulet holds a patent for a power supply for electric arc welding. This invention employs a saturable reactor circuit to control the power supply from an alternating current source to the welding electrode. The control circuit varies the current through the control winding of the saturable reactor to provide the desired welding current. An additional circuit monitors the welding current and disables the saturable reactor control circuit when the welding current drops below a low threshold value. This feature reduces the open circuit voltage between the welding electrode and workpiece, minimizing the danger of electric shock to the welder while changing electrodes. The saturable reactor is connected in series with the primary winding of a transformer, which also serves as the output winding of the saturable reactor. Roulet's patent is a testament to his innovative spirit and dedication to improving welding technology.
