1.Based on the technology of the HF inverter with IGBT module.The frequency is as high as 20KHZ. The reaction is fast;
2.The PWM control method guarantees the quality and stable performance ;
3.Digital display of current and voltage adjustment before welding. Direct and convenient; 
4.Applicable for all the welding positions as the welding current will be automatically adjusted when the stretching length is not more than 30mm ; 
5.Stalbe welding with strong capability against power fluctuation (310V-450V).
