Geomembrane Hot Wedge Welder is for welding HDPE, LDPE, EVA, PVC, ECB, PP thermo plastic materials, which used in waterproofing projects like tunnels, subway, water conservancy, farming, solid waste landfills, chemical mining industry, sewage treatment, roofing and so on.
The control of this series adopt PID automatic thermostatic control with high control and low temperature fluctuation. Speed control of this series adopt PWM automatic voltage and regulation speed circuit. Direct current servo the motor drive with great output torque and staple performance in walking. It can maintain a constant speed on the condition of creeping, vertical creeping and road load. Also this series of welding machine are stable in performance despite of external temperature and voltage variation.
