This machine is special for winding coils for high voltage and super high voltage transformers. The chuck can raise/drop
according to the height of coil so as to keep the working height.
This machine is inverter control, with stable start-up, low noise and easy
operation.
It is equipped with electronic counter which can reduce turns when reversing.
It can automatically stop at pre-set turns.
