The utility model discloses an
control circuit and electric
welding machine.
Control circuit includes: control panel and control module, control panel is used to receive first input
signal, and control module is used for connecting load, at least one first communication module is connected between control panel and
bus, and first communication module is used to convert first input
signal into first communication
signal, and first communication signal is transmitted to
bus, at least one second communication module is connected between
bus and control module, and second communication module is used to receive first communication signal and convert first communication signal into first
control signal, and control module is used for controlling load work according to first
control signal. The
control circuit has obtained the beneficial effect of not needing to transform the core communication logic of original control panel and control module, and greatly reducing hardware modification and protocol adjustment
workload.
