Features:
1, Use medium frequency inverter controller, welding current is DC,1000Hz, so welding current is more stable.
2, Saving energy. Lower welding current and pressure ofelectrode;
3, Top quality. Comparing with traditional AC welders, the weldingstability and concordance are better, as less crator, morebeautiful, more firm.
4, There phase power supply input evenly, lower strike force toPower Grid.
7, Equipped with PLC touch screen, LED display clearly, easy toadjust and operate

Constitute:
1, Machine body of thick steel sheet, not easy to deformation
2, Microcomputer control, accuracy and steady
3, Water cooling transformer: Use silicon sheets of 15000 gausspermeability to pile up. There is cooling water in inside, usingfull copper alloy core, reducing impedance, improving theutilization of power, 20% duty cycle to ensure the requirement oflong time welding, big output power. The useful lifetime is longer,noise is smaller, structure is more compact and reasonable.
4, Fast solenoid valve, making welding speed faster, thereby theproductivity is higher, therefore decreasing cost.
5, Cylinder adopt high accurate, anti-friction hard material, whichis duralumin, without rust, lower friction, lower noise and loadingis faster, thereby reducing the weld spatter.
6, Quality is stable, failure rate is low, therefore machine lifeis longer

It is special suitable for spot welding of Aluminum plate.
