How to calibrate your BK3050 solder pot (Calibrate Soldering Equipment)

This post will apart of a series of How-To calibrate soldering equipment.

In order to properly calibrate the temperature for your BK3050 solder pot, you will require an accurate and precise thermocouple, capable of tolerating up to 500 degrees celsius. If you don’t already own one, we sell a type K, -14-750 degree celsius, accurate to +/- 1%, with a precision of 1 digit. You will also need a small pool of solder, in order to get an accurate result. Typically you’d use a solder ingot with a solder pot, but in this case, you only need a few mm of solder to properly calibrate soldering equipment.

The first step in this procedure is to remove the 6 front screws on the BK3050, and insert your thermometer into the solder pool.

After you’ve opened the unit, there are two blue trim style potentiometers(pots). The one on the far left is for setting the displayed temperature.

To calibrate the setting, set the front panel button to display real temp, then use your thermocouple to read what the temperature is. Make sure you have a few mm of solder in the crucible. Turn the pot either clockwise or counterclockwise to increase or decrease the temperature on the display readout to match the temperature shown on your thermometer. When this has been set to the highest accuracy you can achieve, we now need to calibrate the temperature regulation sensor.

Push the front panel button again, this time to the set display to readout with the unit temperature is set to.

Now turn the pot in the center of the board, clockwise or counterclockwise just like we did in the previous step.

This step takes some time, and patience. You must wait for the solder pot to readjust it’s hold temperature, before turning the pot again. The controller will either apply heat, or turn the heater off based on the sensor reading, in conjunction with this pot. If the heater isn’t heating enough, you need to set this pot to read a lower temperature, and vice versa.

After you’ve finished this step, you’ve finished the calibration of your solder pot. Check back for for links, and the continuance of our calibrate soldering equipment HowTo’s.
