Abstract

Se proporciona un sistema de soldadura. El sistema de soldadura incluye un transceptor de baja potencia configurado para ser acoplado a un cable de soldadura. El transceptor de baja potencia incluye un transmisor de baja potencia, un receptor de baja potencia, y un primer procesador. El receptor de baja potencia esta configurado para transmitir uno o más tonos no modulados a través del cable de soldadura a un suministro de energía de soldadura. El receptor de baja potencia esta configurado para recibir el uno o más tonos no modulados a través del cable de soldadura desde el suministro de energía de soldadura. El primer procesador esta configurado para determinar uno o más coeficientes de filtro de ecualización de de canal, relacionados con el cable de soldadura, que corresponden a una característica de distorsión del cable de soldadura.
