Electrical – Voltage convert from 110v to 220v


Should the ceramic heater in soldering iron be changed to convert the iron from 110 volt to 220 volt? What about the Thyristor?

I know getting new iron is better, but my question is just for learning.
Thank you

For a "simple" iron, where the heating element is directly connected to the AC line, you would need to change the heating element to operate on a different voltage.

For a modern temperature-controlled iron, the heating element likely operates from a low voltage, so you would have to change the power upply/temperature controller.

In either case, the easiest solution is to buy a new iron designed to operate from the available voltage.
