Default Homemade Resistance Soldering Unit

That's right, lower voltage, higher current. When the voltage is too high,
you will just get arcing and pitting of the parts and electrodes.

As to transformers, keep poking about on Ebay. I picked up some a while
back.

Bradford,
My unit works...sort of. It ran long enough to get two pieces of .005
brass sheet strips soldered together before the internal breaker kicked
in. It takes a little bit for it to cool before I could try it again.
Even soldering the .005 strips took about 5-6 seconds. The commercial
units will do it in about 3. I just need more power coming out of the
carbon rod, which I "think" is more amps and maybe lower volts.
