Sealed oil pan and 260mm arm.

Digital Feed Dog Movement

4 elliptical movements depending on the fabric you use, choose between normal, smooth, soft or Heavy Duty fabric.

Fabric Thickness Detection

Thanks to a sensor, the machine detects a different thickness and modifies the movement of the jaw, to always maintain the same stitch length even on unevenness.

Sewing Patterns

You can create beautiful ornamental stitches, thanks to the alternating stitch length. They can also be modified according to different needs.

Digital Stitch Length

Thanks to the new step motor that controls the bartack, it was possible to remove the classic mechanical lever and make its use much quieter and easier with a button.

Silent Bartack

Thanks to the structure of the stepper motor for electronic bartack, the noise has been drastically reduced: this allows you to work in a quieter and more comfortable working environment.

No Oil

The oil pan is sealed, prevents the entry of dust, keeping the machine clean and resistant, ensuring perfect lubrication.

Voice Guide

Using the machine, it will teach you the various functions herself, if there are any errors it will notify you and by clicking on the VOICE button it will suggest how to solve the problem

Short Thread

You no longer need to cut the remaining thread: this avoids the risk of ruining the work and saves time and money. Furthermore, it is possible to insert the final and / or initial condensation stitch to avoid the decay of the stitch.

Industry 4.0 (Optional)

Thanks to the integrated WIFI module you can modify the parameters and control the productivity of the machine directly from the application. NB: a Jack gateway must be purchased for every 50 machines
