Great soldering iron though. **Q: Does it have a automatic shut-off? I don't wanna burn the barn down ;)** A: Dear customer: This pro32 has a automatic shut-off. It will trigger the sleep mode when you leave it for more than 3 minutes, and the temperature will automactically adjust to preset sleep temperature. **Q: Which model adapter did you all get to replace the supplied one?** A: You mean the Power Mains Adapter ?So I habe bought a strong 12 V to 19 V (KFZ) Notebook Charger. (One of the supplied connectors fits)For Home Use, I also recommend a good Notebook Adapter with long Cables. I don´t have bought one till noch, but maybe:https://www.amazon.de/VGP-AC19V30-VGP-AC19V31-VGP-AC19V32-VGP-AC19V37-VGP-AC19V41/dp/B0084CKTG6/ref=sr_1_31?ie=UTF8&qid=1480792139&sr=8-31&keywords=laptop+adapter **Q: Is the Ground cable necessary?
