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.

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。

When choosing a value for R6, ensure that Q2's base-emitter voltage is less than approximately 0.5V at the maximum permissible value of the load current.

选择R6的阻值时要确保在负载电流的最高允许值的条件下，Q2的基极-发射极电压大约低于0.5V。
