Sorry for such a stupid question, but I want to clarify. Here, for example, we have a 10W soldering iron. We turn it on, the heating went on. Assuming that all the work goes into heating the tip, you can calculate how much heat the soldering iron will release in a minute. A=Q=10W * 60s = 600J. From this, the change in temperature can be calculated. But after all, if you leave the soldering iron for 6 hours, the sting will not melt, will it? So there is some kind of attachment. Thank you.

Until a balance is reached between heat production and its release to the environment.

The soldering iron (by the way, not only the tip will heat up, but also the case - the thermal insulation is not ideal) will give off heat through infrared radiation and convection heat transfer to the air.
