Maybe the over-current protection is activated.

1) If the fault indicator is still on, switch off the device
and plug out the power supply plug of the HF arc
striking power supply.
a. If the fault indicator is still on, it will indicate that
some field-effect tubes on the MOS plate are broken.
Find and replace them with the ones of the same type.

b. If the fault indicator is off, it will indicate that the
voltage
rise transformer in the HF arc striking circuit on the
power supply plate is broken. Replace it.
2) If the fault indicator is off:

b. Maybe some the secondary rectifying tubes of the
transformer are punctured. Find and replace with the
ones of the same type.
