World's Fastest RF soldering iron - Metcal challenge

There's been a bit of discussion about these new OLED equipped soldering irons from China. This is a 1994 RF soldering iron from Metcal. An optional RF power meter is inline between the power source and the rework handle, which shows the flow of power into the work. With 45W of RF, the metcal doesn't need to "recover", even when soldering large objects, like this penny, or power pins feeding multiple pcb plane layers without thermal vias.
