The Stitch Length Dial and Differential Feed Dial on the Amber™ Air
S400 provide versatile control over your stitching, allowing you to
fine-tune your serging for a professional finish on any fabric. This
dual-functionality dial makes it easy to adjust both stitch length and
fabric feed in one convenient location, ensuring precise control without
complicated settings.
With the Stitch Length Dial, you can
customize the length of your stitches, creating everything from tightly
spaced seams to elongated, decorative stitches. This flexibility lets
you adapt to various fabric types, ensuring your work is tailored
perfectly to each project.
The Differential Feed Dial offers
seamless control over the fabric feed rate, preventing common issues
like puckering on lightweight fabrics or stretching on knits. Adjusting
this dial allows you to maintain smooth, flat seams or create
intentional effects like gathers or ripples for more creative designs.

The Lighting on the Amber Air S400 Serger is specifically engineered to provide optimal visibility across your sewing area. While it may not use LED technology, the carefully placed lights are designed to produce a steady, bright glow, ensuring that every stitch and detail is clearly visible. This illumination minimizes shadows and helps reduce eye strain, so you can work comfortably on both light and dark fabrics, as well as intricate or high-contrast patterns. Whether handling fine threads, working with challenging fabric textures, or sewing during extended sessions, the lighting system provides consistent, balanced illumination, making your serging experience both enjoyable and efficient.
