E.g. 100KHZ.After reducing the voltage and rectifying,output powerful Dcwith the technology of PWM.The weight and size of the main transformer decrease dramatically but the efficiency will rise by over 30%1.With the function of auto-compensation against power fluctuation.And the ouput welding current will be stable2.Having the function of auto-protection against over-voltage and over-current;3.Having powerful arc-force;4.Reliable quality with small dimension and weight as well as high efficieny;5.Able to weld basic and acid electrodes; url:http://www.dthmachines.com |
