Not to get off/on topic

.....but I just hit the money setting for 30g kanthal and 28g nickel for an awesome .... weld!!!
2200uf cap
34.5 volts
Kanthal in positive clamp/nickel in negative clamp
Quoted from a while ago, but I finally wanted to make a new coil, and started experimenting with
my welder.
I used 5400uF of capacitance, and after about a dozen tries at different voltages, I got a good .... weld.

I ended up with about 3/16" of that end of the resistance wire being (seemingly) more rigid from the abuse, but it worked fine. I was at 22.5V, and tried the other end right at that voltage as well. The second end welded well on the third try, as I recall others mentioning before.
I wrapped the coil around two sewing needles that just fit into the slots on the head, and pulled the legs tightly as I compressed the coil, which is my usual method. The welds stood up to that just fine. I'm vaping on it at 10W as I type this.
Anyway, after looking back a bit to compare energy levels, I found that I was really close to yours: 2200uF at 34.5V = 1.309 Joules.
Mine was: 5400uF at 22.5V = 1.367 Joules. That was on 32 gauge nichrome to 32 gauge nickel jewelry wire, a bit smaller in diameter than yours.
Good stuff! Another thing that I have noticed is that I don't seem to be getting the usual flooding that occurs when I have the tank filled to the wick. My last setup was pretty bad about that, and I wonder if the twisted legs were wicking some of the liquid down, as I had an unusually high-helix spiral wrap on my last coil legs. I guess time will tell on that.
Cheers!
