[0035] In this embodiment, the input power of the welding control circuit 42 and the charging control circuit 43 are controlled separately by separate contactors, so that charging and welding are controlled independently without interfering with each other, thereby ensuring the stability and reliability of the welding and charging power outputs.

[0036] In this embodiment, by setting up a charging socket converter to be connected to the output end of the charging control circuit 43, it is possible to simultaneously charge devices with different interfaces.
