i just got the parts needed to try to convert it into a spot welder
i'll update this thread when I'll start working on it - especially if it's a spectacular failure
(i'll do the first test outside to minimize the things that can burn, if I'll make a 18650 cell  blow up)

im interested in this mod, too. would like to know if this device is suited to spot welder 0.1mm sheets of stainless steel. Which electrodes do you use?
ealex:
hello
the project is currently on hold - i've been busy with some other things.
pretty much everything is done, I just need to connect everything and test it.

for electrodes i plan to use some thick copper wire that's connected to the output cables with some stainless steel screws
friedolino:
do you have more ressources / references for spot weling with arc welding machine?

I found only this video:


ealex:
no, i don't have any extra info.

and the bad part is that I don't have where to get any - the entire area is dead from the machining point of view - i'm just experimenting / learning everything as I go.


(dead - took me 3 months to find someone with a lathe, to make a part that needed 30 minutes of work)
acruse60:
does the cooling fan start running when power is switched on?
