A really bad soldering iron

I picked this soldering iron out of the ewaste recycling stream that students dump at the end of the year, figuring I could use another iron. I knew it ran hot. Yesterday I was attempting to create a data cable between a PC and a radio and was annoyed at how quickly oxidized the tip had gotten. After cleaning it and trying again (failing ultimately because the PS/2 keyboard connector happens to not use one of the pins) I noticed a subtle warm color to it--and thinking it was just the orange light pollution reflecting off of it, but then I put two and two together and realized it was black body radiation. And that means this soldering iron is really really bad.
The camera appears to have a fairly good IR block filter on it, so the colors match better to the eye's response. On a weaker camera I would expect a purple appearance to it as the blue Bayer filter will pass IR circa 900nm.

    Soldering fluxes are really useful for those with an interest in electronics. The purpose of this post is to review the uses of soldering wire from some of the leading types of soldering flux products. Soldering is often used in electronics when components or parts need to be bonded together and to remain bounded. Rosin flux soldering is one type of flux used by people working with electronics. Another type of flux commonly used is lead free soldering flux, which is better for the environment as well as the health of whoever uses it.
