1. Advanced IGBT inverter technology, stable performance, 85% working efficiency, samll no-load lose ,easy to use, convenient to carry;
2.high duty cycle:100% in normal temperature(means it can continue working for 24 hours without stop), even in the temperature 40, it can arrive to 60% working in the full current
3.Precise control system: PWM Pulse Width Modulator, closed loop control system
