Medium Frequency DC Inverter Resistance Welders Spot Welding Machine
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 of electrode;
3, Top quality. Comparing with traditional AC welders, the welding stability and concordance are better, as less crator, more beautiful, more firm.
4, There phase power supply input evenly, lower strike force to Power Grid.
5. less power supply needs, saving 40% electricity than AC Welding machine
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 gauss permeability to pile up. There is cooling water in inside, using full copper alloy core, reducing impedance, improving the utilization of power, 20% duty cycle to ensure the requirement of long 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 the productivity is higher, therefore decreasing cost.
5, Cylinder adopt high accurate, anti-friction hard material, which is duralumin, without rust, lower friction, lower noise and loading is faster, thereby reducing the weld spatter.
6, Quality is stable, failure rate is low, therefore machine life is longer
It is special suitable for spot welding of Aluminum plate.
