领先桥臂中点电压变换期间，变压器初级电流基本保持最大值，使得领先桥臂容易实现软开关；
In the midpoint voltage of leading leg transition, its soft switching is easily realized because of the primary current of transformer keeping the maximum.
使用人员应记得随时观察最大的允许负载电流（相对可选定的负载持续率），保持焊接电流不超过最大的允许负载电流。
Use should always remember to observe the largest load current (relative to the load can be selected sustained rate), maintaining welding current is not allowed to exceed the maximum load current.
有助于保持设计的精确度，并能够减小谐振器中的最大电流密度。
Maintaining the accuracy of design is facilitated and a reduction in the maximum current density in the resonator is enabled.
