1. Stepper shearing/loose wire: the use of stepper motor to drive the wire shearing, the wire cutting is ultra-quiet; Instead of the traditional shearing electromagnet, the motor is more durable.2. Step inverted seam: Step drive loose thread, avoid the loose line does not return to the phenomenon, better stability.3. Stepping table presser foot: The lifting foot is ultra-quiet, replacing the traditional pressure lifting foot electromagnet, the motor is more durable, and the height of the lifting foot is adjustable.4. Pattern seam tight seam function (thread head is not scattered): stepper motor control, can be set to produce 1 -9 kinds of pattern stitches.
