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 automaticvoltage and speed regulation circuit, driven by DC servo motor, with great output torque andthe 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 performancedespite of external temperature and voltage variation.This series of welding machine is excellent in performance and easy for operating, with highwelding speed and good work quality. It is extensively used in engineering projects such as expressways, tunnels, reservoirs, waterproof of construction and so on.
