BIFRC spot welder: circuit design improvements part 2

this video shows how to get the maximum reliability and performance from the cheap BIRFC board, moreover you can get also information in order to build a new board's version by yourself just buying the power MOSFETs apart and IC's commonly available on market.
- part 1: design discussion
- part 2: prototype testing
- part 3: final testing
In this part the breadboard is used to preliminary testing the pulses sent to the power MOSFETS, moreover, the output turn on/off of the MOSFETs are shown to verify possible anomalies before the final test (part 3).
