Hi,
I have two circuits, one is a simplified version of the other. It is used for zero cross detection in a welding machine.
The trouble is that the stripped down version is giving me zero crossing signal 30 degrees before the other circuit.
Can anyone please take a look see if you can see what I'v done wrong?
Many thanks.
