1. Compact design: trolley, water tank, power source can be selected according to applications.

2.  Microprocessor control: simple operation, more perfect welding performance.

3. Comprehensive protecting function, with the protection of overvoltage, under voltage, default phase, against lightning stroke, overcurrent, over heat etc.

4. The unique air duct design: failure rate greatly reduced, extending the service life of the machine.

5. Unitization design: the machine design consists of 4 units-control unit, input unit, inverter unit, output unit. Only need replace the related unit power board for maintenance, but professional debugging is unnecessary.
