First i thank you for taking time to read this
the firing circuit is not connected to the thyristor in pic1
but when i connect the F.C to the thyristor the signal changes as in pic2 ?
what should i do ?

What is the voltage at R3 doing?

Note that your schematics would be easier to read if you took the time to move the components and take out all the kinks in the wiring.
