Increased needle penetration
When the needle penetration resistance is increased in cross over seams and extra-thick overlapping of workpiece sewing, the needle penetration force is automatically increased by vibration control.
Enhanced electronic design
We adopted the control circuit board design which has been proven effective in other models and strengthened the ability to cope with the voltage fluctuations. In addition, vibration resistance is improved,and you can use it safely in various environments.
