The SEAMTEK W-900 AT is the first welding machine to feature the innovative low voltage hot-wedge technology from Leister. This new welding machine is based on the proven SEAMTEK 900 AT. During critical points, the speed can be reduced, similar to a sewing machine, simply and without interruption of the welding process. This innovative plastic welding technology guarantees high-quality welding seams. This is also true for delicate materials.
