First point soldering iron produces a sound similar to a missile, actually very pleasant if you are still a child inside. The heating time is great, in seconds, can be welded, however, the cooling time is long enough. however, it is possible to protect the device with the "plug" of protection, which of course does not touch the hot tip. The operation is quite simple, press the button, and lock it. Very simple. One negative to note is the fill valve. It seems very sensitive and let the gas séchapper if barely touched, but maybe I have a bad model. Bonus point, I fill mine with butane cartridges camping, much cheaper than the butanes cartridges for lighters (the tank is pretty great on this iron ...)
