Here's a question I'm going to ask because while understand basic electricity (E=IR, P = RI^2), I wanted to bounce something off the more savvy guys here and ask would this work or why not? I seem to remember this getting bounced around rec.models.railroad some months back and I don't remember the answer or the reasons for it. That said... Could I use the transformer from a soldering gun to power a resistance soldering unit? I've measured the output at 2 volts or so, so at 100 watts my potential amperage is on the order of someting like 50 amps if I remember the calculations I did a few months ago when I took the reading.(too tired to redo it now). There was some discussions about the transformer not being able to be used like that, because of inductance versus resistance or something. I thought a transformer is a transformer is a transformer (ignoring iron-core and all that).. When I use it for fairly long periods in the gun, the transformer gets warm. Since I'd be putting the same load the gun with resistance soldering (once the joint forms and resistance drops to zero) but for less time, I don't have to worry about overheating the transformer, so would this be workable or not?
