You may drive your average cheap sensitive gate SCR with a 0.1 uf
capacitor between the PIC output port and the SCR gate, and a 1K or so
resistor between the  SCR gate and SCR Cathode.  Make sure with this
arrangement that the SCR Cathode is at PIC signal ground.

I've made no mention of any hazards, or otherwise here.  So be careful!
60+ volts can be deadly.
