Reasons and solutions for the hard start of the quenching machine

1. Check the terminal with the same name of the current transformer to see if the adjustment of the current negative feedback amount is appropriate.

2. Check whether the signal line of the device is too long or too thin.

3.It is necessary to check the intermediate frequency and the isolation transformer to see if there is any damage, especially if there is a short circuit between turns of the transformer. parts are replaced.
