The machine uses an advanced hot-wedge structure , it may be of different material properties for a variety of different sizes and thickness of products welding geomembrane into contact suitable of HDPE , of LDPE , of PVC , E VA , PP and all thermofusible material welding. The temperature control part of this series of welding machines adopts automatic circuit constant temperature D ID control, which has high control accuracy and small temperature fluctuations . The speed control part adopts pulse width modulation (PWM) to maintain a constant temperature when the speed is automatically stabilized . This series of welding machines have stable working performance, convenient operation, high welding efficiency and strong reliability . They are widely used in highways, railways, tunnels, reservoirs, drains, sewage ponds, landfills, building waterproofing and other projects.
