      TIG/MMA Welder
       Product Description :
      Product features
      1.Full bridge inversion soft-switching technology to effectively reduce IGBT working loss;
      2.MCU+DSP+CPLD microcomputer control technology to realize full digital control;
      3.DC manual welding, DC TIG welding, pulse TIG welding, high universality;
      4.2-step, 4-step function selection, welding-related parameters are all adjustable;
      5.Slow pulse rising/descending and constant current rising/descending;
      6.DC manual welding can adjust any striking current and force current;
      7.20 parameter setting passages for independent memory and call;
      8.Wide working voltage range design, 60% of current output can also be ensured when three-phase input voltage is lowered to 250V;
      9.Pulse current rate of rise is adjustable in the machine (please contact the manufacturer);
      10.Multiple protective functions, such as overheat, water shortage, overvoltage, undervoltage, high frequency, as well as reliable property;
      Application:
      Widely used in welding kind of material.
