Tuning should not be required for repeat applications as the parameters are now built into the controller software. However, I will describe the process as it was interesting how additional performance could be obtained from the same hardware by tuning the software.
In Part 1 we looked at the design and hardware for the Soldering Station. This part covers the software, assembly and calibration of the system to provide accurate and reliable temperature control.
After many years persevering with a ‘simple’ soldering iron, I acquired a temperature controlled iron and was amazed at the difference it made to the quality of my work. Recently the iron failed and, although I managed to find the fault and repair it (the temperature sensor wire had broken off), it made me realize that I should keep one as a spare. It is actually quite difficult to repair an iron without an iron!
As I can’t afford to buy an expensive piece of equipment ‘just in case’, I decided to use this as an excuse for a hardware and software project based around a Hakko-FX888 soldering handpiece that I had already purchased.
