Leakage, switch trip

In the process of using the welding machine, the user often has a host that is intact, but the failure of the externally connected accessories causes the host to fail to work, accounting for 4o% of the causes of the welding machine failure. The first step in the concept of what is the external fault: power supply, power line, three-phase power supply 380V, single-phase 220V.

1. There is no phase loss phenomenon in single-phase power, the host does not work, and the fan rotates normally. Check whether the power supply voltage between the main power switch and the host is normal, a...
