The
control of this series of welding machine adopts PID automatic
thermostatic control with high control accuracy and low temperature
fluctuation; speed control adopts PWM automatic voltage and speed
regulation circuit, driven by DC servo motor, with great output
torque and the operating is stable. It can maintain a constant
speed on the condition of creeping, vertical creeping and variable
road load. Also this series of welding machine is stable in
performance despite of external temperature and voltage
variation.
Tianhe
series geomembrane welding machine is our new developed products,
which can weld geomembrane of various thickness and are applicable
for welding of all thermal-fused material such as LDPE, PVC, HDPE,
EVA, PP and the like.
This series of welding machine is excellent in performance and easy
for operating, with high welding speed and good work quality. It is
extensively used in engineering projects such as expressways,
tunnels, reservoirs, waterproof of construction and so
on
