Key Features

• Auto Cornering: After manually releasing a needle, the machine automatically sews a preset number of stitches with one needle before stopping, allowing for easy material rotation. Resume sewing with the pedal, and the machine will lower the second needle as needed. (Optional)

• Electro-Pneumatic Release: This advanced mechanism, controlled by solenoid valves, ensures faster and safer needle disengagement, even at high speeds—superior to traditional mechanical levers. (Optional)

• Short Thread Trimming: The built-in thread trimmer cuts threads to within 3 mm, preventing unraveling and eliminating the need for manual trimming, saving time and reducing costs. (Optional)

• Electronic Tension Control: The electronic tension disc allows for precise adjustments, eliminating mechanical cable limitations and enhancing operational efficiency. (Optional)

• Voice Guidance: The machine features an intuitive voice guide that instructs users on functions, notifies of errors, and offers solutions with a simple button press. A reset button quickly restores factory settings.

• Integrated Foot Lifter: The automatic presser foot lifter, along with the thread trimmer and bartack functions, is seamlessly integrated into the machine’s design, promoting safety and aesthetics.

• Single Shaft Motor: The innovative single-axis design reduces torque and vibrations, providing a stable, fast, and silent operation.

• Spacious Work Area: With dimensions of 264mm x 120mm, the larger workspace facilitates easier garment manipulation for various fabric types.

• Self-Cooling Handwheel: The unique handwheel design enhances air circulation, lowering engine temperature and prolonging the lifespan of electronic components.

• LED Lighting: Three adjustable levels of LED lighting ensure consistent, non-distracting illumination, reducing eye strain during sewing and threading.

• Direct Drive Motor: The eco-friendly 750W motor enhances needle penetration while offering an impressive 71% energy savings compared to conventional motors.

• Industry 4.0 Compatibility (Optional): An integrated Wi-Fi module allows for remote parameter adjustments and productivity monitoring through an app, requiring a Jack gateway for every 50 machines.
