Made to Last: This product is made of high-quality cast iron that has been painted spray-treated to make it resistant to abrasion, rust, and scratches. It is also hard to corrode and deform, so it will last a long time. You are able to create a flat serged seam by adjusting the stitch width with this product’s adjustable needle pitch, which ranges from 0.01 to 0.13 inches.
High Efficiency: It can sew up to 1200 stitches per minute at a maximum power of up to 100W, significantly increasing the edge’s sewing speed and effectively increasing efficiency.
Four-line Design: The width of the four-line design locking edge is up to 0.18-0.22in, compared with the three-line locking edge, it locks the edge better, is more compact and solid, and is not easy to take off the line.
Each bobbin holder on the body corresponds to a thread, and you can rotate counterclockwise to loosen the stitch tension and clockwise to tighten the stitch tension to meet the sewing edge needs of different fabrics.
The product is controlled by a foot switch, allowing you to freely control the sewing process, which is not only convenient for you to operate but also improves the safety of use. In addition to locking the edges, it automatically cuts the cloth and trims the edges while locking the edges. This reduces the process and saves you time and energy.
