Example Embodiment

[0015] The welding machine fault detection and protection system of the present invention includes: a fault signal acquisition circuit 1, a signal latch circuit 2, a signal processing circuit 3, and a display circuit 4 connected in sequence.

[0016] Such as figure 1 As shown: the fault signal acquisition circuit 1 of the present invention includes: an overvoltage signal acquisition circuit 11, an overheat signal acquisition circuit 12, an undervoltage signal acquisition circuit 13, and an overcurrent signal acquisition circuit 14. Since the above-mentioned sampling circuits are all existing technologies, they will not be repeated here.

[0017] Such as figure 2 Shown: the signal latch circuit 2 of the present invention receives the overcurrent, overvoltage, and undervoltage signals from the fault signal acquisition circuit 1, which includes:

[0018] Six-in-phase buffer converter 4050, the over-current, over-voltage, and under-voltage signals are input to pins 3, 5, and 7 of th...
