    Is my soldering iron heating element bad?

    I have a Chinese knock off soldering iron that I've been using for three years.

    Suddenly the soldering iron stopped getting hot. The digital read out increases with knob turning but it always displays 006c

    It's an 852d+ station. Couldn't find anything online for testing heating element so I did an ohm test across what I believe to be the sensor and input lines.

    heat the tip with alighter or something and see if the readout changes.
    chances are, the cable is bad - because your meter readings look like it's probably o.k.

      I applied some current to the + and - terminals. The ceramic got hot and the reading on the other terminals changed.

      I hope it's the wiring and not something inside the system

        Did you really measure 2.1MEGohm across the temperature sensor? or milliohms?
        I would suspect an bad temp sensor if it's that high and display is saying 6°C for a temperature?
        Some info on 852D+ on Russian websites but no "006c" message

          It was Megohms

              It was the heating element. Installed a replacement.

              Question: Is there any need to recalibrate the station when a new heating element is installed or?

                they probably arent calibrated to begin with.

                  Not need to recalibrate.

                    The best way to drive a heating element?
                    by EasyGoing1
                    I've got this circuit that I've been playing with on a breadboard. I'm not happy with it mainly because the MOSFET gets too hot and generally controlling the temp of the heating element with the Arduino has proven to be a little more cumbersome than I would like.

                    What I would like to know, is what is the best way to set up a circuit like this? The heating element is just a PCB and its going to be mounted under a 3D-printed enclosure that a lizard will use to warm his belly.

                    This is the general setup that I have now.



                    This is what the...

                    Yihua 992DA+ Hot air gun and soldering rework station, burnt mark
                    by Peter_1402
                    Hi Everyone,
                    I bought a Yihua 992DA+ hot air gun and soldering iron unit from a used market.
                    1. Soldering iron works great
                    2. There is a burnt mark on the hot air gun handle.
                    I am a bit concern by the look of the melted plastic. I opened the hot air gun handle and took some readings with a multimeter.
                    Heating element ~ 75ohm. (Similar reading taken from a spare heating element that came with the unit.)
                    Thermocouple ~ 1.5ohm. (Similar reading from the spare heating element.)
                    Reed switch tested ok with a magnet.
                    From the above test, I can conclude...

                    [Baku 702B] Soldering iron not heating up and the temperature doesn't go up
                    by datsnow
                    Hi!

                    I'm owner of a Baku 702B. I do some SMD work with it, and since I have a spare soldering iron that works very well for the little soldering that I do, I hardly use the soldering iron that this station comes with.

                    (To add some info, this station went to RMA some months ago, the hot air gun resistance was changed to a new one.)

                    So, some days I needed to use the soldering iron that comes with the station, but for my surprise, the temperature would not rise. The temperature screen would always show 22/23ºc and no matter what, if I rised or decreased the...

                    Opinions on particular soldering iron tip maintenance product
                    by kalemaroni
                    Has anybody tested this product? Posting this question on a Facebook tech group I'm in got a few responses like "that kind of thing corrodes the tips" and "just using normal solder paste is much better" so I'm not looking for generic responses like that, but rather, does anybody know for certain whether this exact product is good or bad for soldering iron tips?

                    Kaiweets USB soldering iron
                    by tony359
                    Hi all,

                    I am testing a USB powered soldering iron. It's made by Kaiweets but I believe it's also sold under other names.

                    As a standard test, I checked whether there was any voltage leak from the tip - that said the thing runs on USB-C power delivery so am I correct that the whole unit is floating and not grounded? If I check, I measure 90V at the tip but I have a feeling that that is not relevant? Maybe caused by that capacitor between primary and secondary inside the PSU? I do not see current flowing at all.

                    In other words, do you think it's expected and...
