and about that arduino welder, I have this exact one, it does a good job but you can't really work fast with it, it gets hot after a while with and it doesn't have pneumatic electrode heads that spread even pressure for each weld.
I build packs for a living, I can't work with that thing all day.
i understand you issues perfectly. i have the exact same issues. but due to pack size i cant use a pnumatic arm so manual electrodes is the only way for me.
inverters simply cant supply this burst of power. you need inverters 10x mores powerful to be able to deliver that pulse without exploding.
prehaps if you have a inverter powerful enough it might just do it but it will not survive. you will blow up the coils and transformers inside the inverter. i know this for a fact because i already tried this. i still have a real industrial class D RCD in my breaker box to prove it and a inverter that is really black on the inside.
if i were you i would focus on getting the pnumatic arm and treat the electronics behind it as a separate project. if the malectrics welder gives up i would recommend getting the K-weld with the supercap expansion and hook that thing up to the pnumatic arm.
as a fellow professional battery builder please trust me and dont trow away your money into fooking about with inverters, its never going to work with stock components. i got almost a 1000 euro's into that dead end in buying them and repairing them to prove it.
a air cooled malectrics welder and some REALLY heavy duty electrodes is the way to go until you get your pnumatic arm.
you know you can build such a thing youself? its not that hard with stock stuff from aliexpress. the wleder electronics are completly separate.
