双回路高频焊机的设计应用

The Design of the Double Return Circuit High Frequency Welding Machine

介绍了双回路高频焊机的制作情况，对该振荡器的线路进行了分析，对低压主回路及控制回路重新改装，冷却系统也进行了改进。实践证明，该设备运行可靠，焊管效率提高，调整维修方便，能耗显著降低。

The manufacture of the double return circuit high frequency welding machine is introduced. The oscillator circuit is analysed. The low voltage main circuit and the control circuit are modified and the cooling system is alsoimproved. By may of practice, it is proved that the equipment runs reliably and is adjusted and repaired conveniently, the efficiency is improved and the energy consumption is reduced remarkably.
