CFW for KSGER/Quicko STM32 Soldering Stations
DavidAlfa:
That's a hack to let the PSU output more power, but it will instantly blow up if the transformer core reaches saturation.
All PSUs can handle more than their nominal power but they must leave some room for safety margin.
If It works, great, but if it goes boom you know why :D

This is not necessary, the HANDSKIT power supply unit is 150 watts, the same AIXUN is used in T3A. just in David's firmware menu for the C245 profile :
1. power 150
2. pwm 10x
3. ADC time 50 or 100ms

This is a revision of my power supply. When using 245 (when the soldering iron tip is cold), the power supply went into protection cyclically.
If you use T12, then this is not observed.
Changed the parameters of the current sensor. On the factory circuit, two 0.43 Ohm resistors are in parallel.
I added another 1.0 ohm resistor. And the power supply stopped going into protection.
Perhaps other instances of Handskit power supplies will not have such a feature.

Am I to understand that you have a HANDSKIT station at your place? Does the tip change feature work in version 1.10.2?
yelkvi:
I have an old version of the firmware. I haven't programmed a new one. No free time. And there is no need for new firmware.

What is the “tip change feature” exactly?
