کوره ذوب القایی repair first power circuit, then functional circuit

The power supply is the heart of the induction melting furnace. If the power supply is not normal, it is impossible to guarantee the normal operation of other parts, and there is no way to check other faults. According to experience, the failure rate of the power supply part accounts for the proportion of the whole machine. Many failures are often caused by the power supply. Therefore, if the power supply circuit is repaired first, it can often get twice the result with half the effort. The induction melting furnace should be repaired in accordance with the main circuit first. The power supply part, the control power supply part, and then the control circuit, the trigger circuit part, and finally the order of the display part. This is because the power source is the energy source for the normal operation of the various parts of the induction melting furnace, and the control circuit is the basis for the normal operation.
