Time frame?

I have a 25 watt soldering iron with a fixed temperature.How much time will it take to get hot ? How am I supposed to know that it is hot?

It differs from iron to iron. I'd say give it 5-10 minutes.

Or... As a general rule, I would say to wait until it can start melting solder, and then give it another 2 minutes.
