特点及用途：

1、通电时间短、热效率高、可有效抑制焊接飞溅、获得稳定高品质的焊接效果，焊接成型美观。

2、控制精度高，中频点焊机由于工作频率高（通常在1-4KHz），使得反馈控制精度是一般交流点凸焊机和次级整流点凸焊机的20-80倍，相应的输出控制精度也非常高。

3、逆变点焊机采用三相输入，宜于电网供电平衡，无须电力补偿设备，对电网无干扰。

4、由于热效率高、焊接变压器小、铁损小，焊接同样的工件比交流点焊机和次级整流点焊机节能可达30%以上。

5、特别适合于导电率较高的铜、铝和镀锌金属等材料，焊接效果良好，尤其适合于三层板焊接、非常薄的材料的焊接以及精密焊接的要求。

Main Features:

1.Current time is short, high thermal efficiency, which can effectively inhibit welding spatter, stability of high quality welding effect, beautiful welding forming

2.Control precision is high, intermediate frequency spot welding machine due to the high working frequency (usually in 1-4 KHZ), the feedback control precision is general ac point convex welder and secondary rectifier point convex welder 20-80 times, the corresponding output is also very high control precision.

3．Inverter spot welding machine adopts three-phase input, like the balance of power supply, no power compensation equipment, no interference of power grids

4.Energy saving: due to the high thermal efficiency, small welding transformer, welding inverter and small iron loss, welding the same artifacts, than ac spot welding machine and secondary rectifying spot welding machine and energy saving can reach more than 30%

5.Wide applicability: can welding materials such as copper, aluminum, and galvanized metal, welding effect is good.Three layer board is especially suitable for welding, welding material is very thin, and the requirements of precision welding
