Review on 🔥 YIHUA 8786D I 2-in-1 Hot Air Rework and Soldering Iron Station with Fahrenheit/Celsius, Cool/Hot Air Conversion, Digital Temperature Correction, and Sleep Function by Chris Ostby

First impressions: I just received it today and couldn't resist trying it myself. I have to say I'm very impressed. The Fahrenheit set came in, which is cool. In any case, most solders are currently available in both temperatures. Everything in the photo has arrived. Top quality tips, similar to those from Hako and Weller. The air nozzles are securely attached, but remember that the smaller the diameter, the longer it will take to cool down. On the smallest diameter, it took about 15-20 seconds to accelerate to 100 degrees and shut down. Wide open, maybe 5. After making sure everything was working I wanted to check the temp. I've seen several reviews about the soldering iron not being able to reach temperature. After testing it with a Pro Heat thermocouple thermostat, I found out why. I put on the smallest bit tip and set it to 600. After warming up for 5 minutes, the reading was barely above 300. Let her sit another 5 minutes and she still reads the same. I followed the instructions for the calibration procedure, which is very simple (the instructions only use the hot air side, but both can be calibrated separately). After that I left it for another 5 minutes and checked again. DEAD! There was a rise and fall of about + or - 15 degrees, which is quite normal for a PID loop. These types of installations do not use direct current as is the case with the simpler rotary dial or direct-to-wall devices. You use a controller and some kind of sensor, probably an RTD, and "pulse" the current to keep the temperature constant. Now let's get to the hot air. Checked his temp the same way and it was accurate and I didn't have to fiddle with it. With the smallest tip and 50% airflow and a temperature of 500, it melted 0.032" diameter solder in a few seconds. The probe turns on when you pick it up, cools down and turns off when you put it in the holder. What more can you say. Conclusion? It's a reliable device. As long as you check the temperature, it should do what you want it to do and then some. I recommend Yihua tighten quality control on calibration. reach temperature. Too high and you run the risk of smoking out the transformer, which I have also seen in test reports. In general I am very satisfied so far. And I will update if anything changes.
