BG412412155 I plan to use with a 5A bench power supply and 3 150,000MFD capacitors. The capacitors are about 2 or 3 times more powerful than needed. Using a 25watt 12ohm power resistor between the power supply and the charge storage capacitors keeps the short circuit current off my power supply, and capacitor charging is monitored by a $3 LED digital volt meter attached to the capacitors. Only takes a couple seconds to charge the caps from dead, but with this new pulse generator I should get multiple pulses per charge, so charge time should noe really be a factor for me. I'm limiting my rig to 1 amp of charge current, so I'm easy on my bench power supply. For you with a 30 amp supply, you could go with a 1 ohm resistor and get fast charges. The 150,000 capacitors are the large "computer grade" power caps, but you can probably use large super caps too if you have the money to spend on them. My big 150,000mfd caps are rated for 40v surge (use around 12v to 14v) and can vaporize a large hole in the top of a battery, so they have plenty of power, I need this welder to generate tunable pulses as adjusting the voltage isn't providing the control I need.
