Soldering Iron....
Uh, no. I'm not. Where I used to work. we had at least 10 of those wellers with failed handles. I don't recall if they used micro switches or reed switches in the handles? But they do fail. There is no need for one of those for home use.
A simple iron makes way more sense for home use and auto use.
I don't really give a ****. Use what you want. Pay your money and use what you want. Don't get your tits in a Great Big twist.
