Follow up Mini Spot Welder revised/different edition (BK11-1K)

Описание: If you like and appreciate my content, feel free to offer me a beer @ my paypal: [email protected] - cheers!

There is (another) flaw in this (and some later) versions - please check your main cap input diode! More info here:

Follow up Mini Spot Welder revised edition (BK11-1K) with more details on problems and fixes (trigger driver resistor replacement).
Here is the model in question:

Here is further description on the problems regarding this version specifically the DRIVER circuit and the 1K resistor swap with a 470Ohm:

P.S. in my version I tested the gate voltage and I did not see 4V on the gates but around 8.4, though I did test this after changing the resistor even if of same value (10K). I suggest changing that resistor in any case, it increases the drive and secures a better saturated ON signal.
