  • Remote sense lead magnitude and polarity controller
    Patent number: 9808880
    Abstract: In a welding power supply, a feedback circuit senses electrical signals from the power output studs and from remote welding sense leads. The feedback control circuit scales the electrical signals and converts the signals to binary numbers having magnitude bits and a polarity bit respectively. The binary numbers, representing the signals, are simultaneously shifted into a logic processor for calculation of a feedback signal based on the digitized input. The feedback signal is calculated based on the polarity of connectivity of the remote welding sense leads as represented by the binary numbers. The feedback signal is then fed into the power supply output controller for automatically adjusting the power output of the arc welder.
