Use should always remember to observe the largest loadcurrent (relative to the load can be selected sustained rate), maintaining welding current is not allowed to exceed the maximumloadcurrent.
Output switch module technology indicators, load it with different types are closely related, in particular, the maximumcurrent output.
开关量输出模块的技术指标，它与不同的负载类型密切相关，特别是输出的最大电流。

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 loadcurrent.
