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.
