  • Yeah, just gonna chime in here real quick.

    I went down this road just as you. I found out that most MOTs are rather weak for 18650 nickel strips.

    You need a transformer rated around 1500 watts. Most are 700-900 watts. I ended up wiring 2 transformers in parallel. Also, make sure to remove the transformer’s shunts. They are a form of current limiting and will impact your amps at the end.

    Finally, make sure to carefully regulate your pressure with the copper tips. High pressure does indeed equal a weaker weld.

    AC in general is also not the best for very short pulses of welds. I have found that 40-60ms work best for 0.2 with around 1000amps. Anything less didn’t weld tbh and the MOT couldn’t pull amps fast enough. I tried all sorts of windings and cable thicknesses. I finally chose 6AWG and I’m happy enough with 2 transformers.





  • Hmm, maybe I should have clarified. You would be correct if I was talking about doubling the overall power. I meant simply adding another turn to my secondary coils so as to raise the voltage and lower the amps a bit or to connect the 2 transformers in series.

    Caps seem like a decent idea actually. The house is rated for something north of 40 amps so I should be fine for a ms load.




  • Hmm, this is an interesting one.

    I rarely play alone anymore. Which makes it even more difficult as you get older. It’s hard to match up with other people when life keeps them equally busy.

    I’ve also noticed that I want a new experience from my games, kind of like searching for that new movie. Games rich in their story and yet not that distracted in side quests seem to keep me going. God of War was ideal, Horizon too. Baldurs Gate 3 had me for a while, but most online titles suck the time out of me at almost no return.
