What's wrong with the induction melting  furnace working normally but the power does not go up?

The normal operation of the equipment can only indicate that the components of the equipment are intact. If the power is not up, it means that the parameters of the intermediate frequency furnace equipment are not adjusted properly. (1) The rectifier part is not adjusted properly, the rectifier tube is not completely turned on, and the DC voltage does not reach the rated value to affect the power output. (2) Adjusting the IF voltage value too high or too low affects the power output. (3) Improper adjustment of the interception and interception value makes the power output low. (4) Unmatched furnace body and power supply seriously affects power output. (5) If the compensation capacitor is configured too much or too little, the power output with the best electrical and thermal efficiency cannot be obtained, that is, the best economic power output cannot be obtained. (6) The distributed inductance of the output circuit and the additional inductance of the resonance circuit are too large, affecting the maximum power output.
