I have had a problem for some time.
my board got short-circuited for my welder.
the welding company doesn´t exist anymore.
Now i want to repair my welder, since it isn´t cheap to replace it.
I have a bipolar transistor called ST-4 wich i can´t find anywhere. the middle leg is not connected to the circuit, and have been cut. then i have a BC237B wich is common.
Do anyone know where i can find such transistor, with the specific name ST-4?
