1, Use medium frequency inverter controller, welding current is DC, 1000Hz.
2, Saving energy.
3, Top quality.
4, There phase power supply input evenly.
5. less power supply needs, saving 40% electricity than AC Welding machine.
1, Machine body of thick steel sheet, not easy to deformation.
2, Microcomputer control.
3, Water cooling transformer: Use silicon sheets of 15000 gauss permeability to pile up. .
4, Fast solenoid valve, making welding speed faster.
5, Cylinder adopt high accurate, anti-friction hard material, which is duralumin.
6, Quality is stable, failure rate is low.
It is special suitable for spot welding of Aluminum plate.
