In terms of heating then yes, it will work. You need to apply the same equivalent DC voltage as the AC RMS value. So 220 volts AC needs 220 volts DC to produce the same heating.

I would add that high voltage DC supplies are more dangerous than AC (if you got hold of them) and that DC voltage will turn the iron into a magnet while it is on.

Many soldering irons have an integral diode, because it allows for a thicker, more robust resistive wire (JBC for example). If you connect such an iron on DC or full wave rectified AC, it will either stay cold or blow in a matter of minutes depending on the polarity.

It would be a good idea to check that there is no series diode before attempting that

buy an adjustable or temp controlled station, they are cheap cheap cheap if you buy an import... or buy urself a Variac which is very useful elsewhere, and still pretty cheap for a 1-3amp sized unit, and just adjust the AC voltage +/- for temperature setting.
