Follow along for a hands-on demonstration that highlights performance points. In this video, we showcase the SWT-NS700 HDPE liner welding machine in action, showing how its high-power hot air heating system delivers efficient, high-quality welds on PVC and geomembrane liners. You'll see the machine's adjustable speed and temperature controls, observe the welding process on materials from 0.5 to 2.0mm thick, and learn how it performs in demanding environments like tunnels, landfills, and water conservancy projects.
