Hi guys !
I added a bridge rectifier to an AC welder + inductors + capacitors to be able to weld DC...
The capacitors I have are 2x 2200µF @400V the output voltage is only 90VDC but the capacitance is not enough for welding DCEP with 7018 electrodes which keep on sticking instead of initiating the arc.
I do have a 10000µF @50V capacitor on hand, I am thinking about wiring it in series with the other two hoping it will be ok @ 90VDC across the chain +2200µF-+10000µF-+2200µF-...
I need advice since I am not sure whether the unbalance will have side effects... I don't want a ~1KG cap to explode on me...a tiny one is scary enough.
So, is it safe to proceed or will it go BANG!!! ???
Thanks very much !
