SMC component soldering is done at 185C , Through hole is around 250C. I don't need any more than that . Heavier gauge wire I have to go higher for sure .Very rarely do I need to go higher than 350C and that for 14 gauge solid wire. I can tell the difference between Celsius and Fahrenheit since I have to use both all the time.

I checked the specs and it indicates the minimum temp of the station is 200C. So you solder at 2C above the melting point of 183C? Not that I don't believe you, but I think the actual tip temp is higher than you think it is.

luke9511:
i do all of my soldering at 375c

mcovington:
I think a lot depends on the kind of solder -- you are not only melting the solder, you're also activating the flux, and some fluxes surely require more heat than others.

I will underscore someone else's remark that the temperature reading on the controller may be off by as much as 50 C.

And also someone else's observation that it's easier to overheat components with an iron that is a little too cool than one that is a little too hot.

hmm. Maybe it's broken.I'll have to get that checked. It still has warranty.
I should get a tester but not sure which one to get without taking out a small loan. And I'm skeptical about those super cheap ebay ones .
Any way the point I was making is  watts and  heat. Yes having the right heat is important but sustaining that heat is just as important.

You should be skeptical about cheap instruments, but they are often fine for occasional light use.  Cross check the reading when it arrives e.g. using a multimeter with a temperature setting.  If not, buy a cheap thermocouple meter at the same time.  Those $4 thermocouple meters are useful elsewhere, such as monitoring board temperatures.
