I have this iron. No better than many other cheap Chinese 30w irons. If you use it with the wrong soldiering iron holder, the plastic at the top of the handle will melt. If you are handy enough with a soldering iron to go anywhere near a PCB with one of these, you know enough not to go anywhere near a PCB with one of these and already have a better iron. I used the 12w antex for many years before switching to a hakko clone, never going back. The difference soldering with a higher wattage temperature controller iron is night and day.
Just plug it into a cheap plug-in dimmer :-)
30W? crikey! You could almost goose your average surface mounted components from the other side of the room! I've not used anything that powerful since I used to work on valve radios nearly 50 years ago. My "weapon of choice" is usually a 12W M12 (and even then, it can be a bit hefty on fine tracks!) and when that isn't enough, my 18W usually does the job! Still, I can't say a bad word about Antex, they really are the soldering bolts against winch all others should be compared. Cheap as (fried) chips so voted hot anyway
I’ll keep my on one in Amazon they always go up and down in price I’ll snap one up on sale
