I've had one of those Dremel soldering irons for a while - I bought it for a project I haven't started yet so it hasn't really been used in anger. However yesterday I used it to solder the wire back on the rear contact of my Nippy's dash light. The connection was originally crimped and is very close to a paxolin(?) insulator which I worried about melting. However I found that the butane iron gets way hotter than my old (ancient) electric iron and can be directed with greater precision. I was able to get the solder in and get out again without affecting the insulator. The thing to watch out for is the 'exhaust' from the butane flame an inch or so above the tip - I was working on top of a scrap of painted wood and I could see the paint blistering. And fingers of course!
