Resistance Soldering

[Hershey]

HI all...been looking around the forum and can't find an answer to my most burning question (pun intended)..
I want to build a resistance solderer...saw a couple places where they talk about using a regular battery charger as a power source....what I am wondering is if instead of a regular battery charger, you could use the output of a Battery Tender??? 12v at 1.5 amps I'm thinking, should be enough to do the job. Any one ever do this or is it just wishful thinking on my part?
Thanks...

it works better if you use low voltage, say three to six volts, and a much higher amperage, say ten to thirty ..
i made one out of a battery charger, used the 6 volt taps ..

Ah,thanks....asking because I have an extra battery tender, but not an extra battery charger...maybe I'll give the tender a try...don't know about overload protection in the tender though, it might not work if the current draw is too high what with the tips actually being in a 'short' condition...but then if it doesn't work, I can pitch it and go with the charger....
