This often is called overshoot and can cause a problem when load circuitry is not able to tolerate the higher voltage. Adding or increasing a soft-start circuit often reduces unwanted start-up ...

There’s one limitation to the combo: the unit uses a switch to either power an attached TS100 iron, or act as a general DC power supply. It cannot do both at once.
