I'm far from an expert but I would think you should avoid a soldering gun around a circuit board or small wires since it puts out so much heat which would can burn up a component or melt the insulation quickly. I believe those are considered medium range.
I bought a cheap Wellerman soldering iron for like $10-15 and did my entire MegaSquirt install with it. It didn't have enough heat to solder an 8 gauge wire together, but for the 20-22 AWG wires, it worked perfect.
Plumbing uses acid core which should be avoided for electronics, rather use a rosin flux. I was recommended 60% tin, 40% lead solder for the work I was doing. Can't remember diameter but it is (IIRC) high 0.020" to low 0.030" size for small wiring.
