SW-Series programmable automatic winding machine is applicable to produce small transformers, power supply transformers, relays, ignition coils, switching power supply transformers. Reciprocal wire traverse operation can be performed accurately and different winding pitches can be set at random, such as close winding, loose winding and parallel winding, etc. Prior to winding, enter the specification data into the controller by pressing the numerical key. The programming winding parameter can be set up in a short time for production. Microprocessor design, easy operation.
