Well, I'm busy with the dual pulse code for the processor and also a couple of bugs that is p***ing me off :)) I guess everyone is asking "why so many Mosfets?". Many Mosfets in parallel lowers the resistance that lowers the heat and increase the amps. The difference between six of these Mosfets and eighteen is a couple of hundred amps more and a welder that is not going to overheat and burn out. You can also see that I get excellent controlled welds at much lower energy rates than commercial welders out there. I'm also turning this Mosfets on and off at precise calculated speeds according to the data sheets to prevent them from going up in smoke.
I'm in the process of ordering more boards and will hopefully be done with the programming by the time they come in to make it available to you guys.
