We tested it—see the highlights and what to expect in real operation. In this video, we demonstrate the SWT-NSGM1 HDPE geomembrane welder with stainless steel heat wedge, showing how it performs in waterproofing applications. Watch as we walk through its intelligent digital controls, adjustable temperature settings, and consistent welding quality on PVC geomembranes from 0.2-2.0mm thickness.
