Cordless soldering irons, wire splicing Options

[vitamin914]

I have mostly used soldering stations (Metcal and Hakko) that have adjustable temperature controls. Great for benchwork, not so much when you are upside down under the dash.

Weller, Milwaukee, Hakko make some battery powered units and Ive seen some no name butane powered irons. None seem to have much in the way of good temperature control. Twenty years ago I had a butane micro torch / soldiering iron - didn't like it at all. The solder would oxidize in seconds (dross up) and I was forever trying to keeping it clean no matter how low I kept the flame. Put it down the wrong way and the exhaust port would burn the table. I did like the micro torch tip for shrinking heat shrink tubing but that was about it.

Anyone have experiences with newer cordless soldering irons - battery or butane?

I have a cheap radio shack special butane soldering iron. I've had it for at least 10 years and use it all the time. I've never had a soldered wire fail. It's definitely messier than my benchtop and the temp adjustment doesn't work great. But for soldering automotive stuff, it works great.
