Would it be possible using say two capacitors to pause and build up voltage then release them at the same time increasing the ,I don' t know , potential amps to get more out of the circuit and be able to weld thicker stuff .
Over the years I spent a lot of time trying to find the best weave, only now that I have a constant shake do I feel content !
Sure, if you're spot welding, or welding thermocouple wires together. They are often built as capacitor banks.
If you want to weld a bead, the problem is that your average current will not change - You can't get more out of the circuit than you put into it. If the welder is capable of providing 100 amps, and you set up capacitors to give a 300 amp pulse, then the absolute maximum part of the time you could get that pulse for would be 1/3. Due to losses, etc, probably more like 1/4, or 1/5, so the total heat into the metal would actually be less than the 100 amp welder straight up.
I've welded pulsed tig befor and used the same setting that I had with out the pulse maybe so I though but I don't think so , you know ?
