I was on the verge of building a capacitive-discharge spot welder to join a mess of NiCad batteries for cordless tools.
Then I got to wondering. And wondering. Whether a 90-amp MIG welder would substitute? Seems like 0.030" wire is pretty close to a spot weld...
Anyone ever try this or something similar?
I guess I could experiment, but preliminary cautions and advice would be appreciated.
Thanks.
