If you're soldering to PCB (printed circuit boards) or other similar electronics which have pre-existing solder pads, you run the risk of lifting pads with anything "hotter" than a 30 watt iron.

30-45 watt pens are basically for pcb, circuit boards & the 140watt gun is for larger jobs, soldering wires together, etc.

30W - fine circuitry (small traces, plastic tracing, Surface Mounts)
45W - regular circuit boards, 12ga and smaller wiring
100W - large gauge wiring mostly, and anything you need concentrated heat on. Also good for stained glass.

I use a 20/40W iron for most of my circuit board repairs on computers and car ECUs. The 40W setting does fine for solder pad capacitor replacement. I set it down to 20W for surface mount components.

At the 40W setting, I've used it for wiring repair on cars up to at least 12ga.

The 100W is really too big for the smaller gauge wiring on cars these days, you'd basically touch it to the junction for an instant, and still might melt the wiring insulation bar farther than you'd want, so you'd want to use a longer piece of heat shrink tubing to compensate.

I bought this 45W and a 25W butane soldering iron for some circuit board work on the dash display of one of my cars yesterday. I'll probably only use the 25W, but won't know until I have the PCB out and take a look.

Paid less than $2 with points for the 45 watt. It wouldn't let me order the gun for pickup, but I could order in the store with free shipping, if I wanted to get the soldering gun.

Not available within 50 miles (any of them) and I don't see option for ship to store, either. Good deal if it was available, though.

besides that, what's the difference between the functionality of 30 watts, 45 watts, and 100 watts? I know they are of different electronic capacity, I am just wondering about the real world functions...
