an easy way to fix it is...... 1)dip fingers in a glass of water and touch the live wire with your index an thumb while holding onto a microwave bag of popcorn. 2) if that doesn't fix your capacitor problem, then get a bigger fucking hammer and give the welder some love taps 3) And swearing always helps too

@johnconrad5487 4 жыл бұрын

Very nice project. However I think you may have a problem. The rectified 325VDC is also supplying the UC3844 via a small value R11 47 Ohm resistor. You also have a winding for the local auxiliary power the 47 Ohms must be changed to about 150KOhms. Then this will also cause startup problems so the capacitors on pin 7 should also be adjusted. Is that why you added the small external power supply?

@YTANDY100 4 жыл бұрын

@ John Conrad it looks like it says 100k next to it , it is a bit confusing having two numbers there :-)

@johnconrad5487 3 жыл бұрын

@@YTANDY100 Thanks. i just noticed it. It says 100X = 4700 Ohms. Even that is not enough. it allows 69mA to flow to the IC which can not take more than 30 mA. He really needs to put a 150K resistor. This will allow about 2 mA to start the chip which only needs 0.5mA to start. Then when the chip starts it will get current from the LM7824 in order to run. Again, LM7824 is too much. He should use LM7812 or LM7815. I have designed many low and high power supplies from 1 watt with input voltage of 400 Volts with Vout = 500 Volts, to 125KVA for Electric Vehicle traction motors but I dont think he will look at my comments.

Sure! But you have to periodically charge that 12v battery so that you can weld with it. My problem with Kasyan's DC welder is that it is too complex. Why not just use a MOT? Remove the high voltage secondary winding and replace it with a few turns of very thick wire for a low voltage secondary. Problem solved.
