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.
