- [27] Q: I am looking to upgrade a production machine to medium frequency direct current (MFDC) to reduce primary load from my three-phase line, improve weld quality, and reduce scrap. The original equipment manufacturer (OEM) we work with has asked us, "What is your welding duty cycle?" What information is needed to determine the MFDC transformer and rectifier duty cycle? How is the correct MFDC power supply and inverter size selected? WELDING JOURNAL, 2021, 100 (09) : 14 - 15
