Key Advantages:

1. USB Port – Standard on the control panel for easy data management and software updates via USB drive. Export quantitative sewing data to a tablet or USB.

   

2. Stepper Motor Presser Foot Lift – Reduces operator fatigue with a maximum lift height of 17mm (standard: 13mm).

   

3. Precision Stitching – Electronic thread tension ensures consistent knotting at the start of each seam.

   

4. Direct-Drive AC Servo Motor – Compact motor connected directly to the upper shaft for fast startup, precise stopping, improved responsiveness, reduced vibration, and low noise.

   

5. Handwheel Positioning – Placed on the arm for clear visibility of the needle drop point.

   

6. Large Sewing Area (40mm × 60mm) – Supports versatile stitching patterns, including long bartacks. High storage capacity for stitch scaling, stitch count, and pattern variations.

   

7. 100 Built-in Patterns & Scaling (20–200% in 1% increments) – Adjust stitch length to resize patterns.

   

8. Multiple Models for Different Fabrics – Operators can select the optimal sewing mode for each task (some applications may require changing presser feet or other parts).
