Compact design: trolley,water tank,power source can be selected according to applications.
Microprocessor control: simple operation,more perfect welding performance.
Comprehensive protecting function: with the protection of overvoltage,under voltage,default phase,against lightning stroke,overcurrent,over heat etc.
The unique air duct design: failure rate greatly reduced,extending the service life of the machine.
Unitization design: the machine consists of 4 units-control unit,input unit,inverter unit,output unit. Only need replace the related unit power board for maintenance,any professional debugging is unnecessary.
