    Hey!

    Being in a situation where I have to move back and forth between Korea and the United States, I acquired a 220V 30W soldering iron that I used for home improvement, mini projects and electronics repair. If I plug this thing in to a 110V socket without a transformer, would it just run at 15W and would it be safe to do so?

    Even if it is safe it's not likely to get hot enough to actually solder.

    If it's a plain resistance element it would be safe at 7 1/2 watts.

    no it would be a quarter of the full wattage, best to buy an iron in the USA for 110v,then use an halfwave diode for use in Korea.
