-JBC HD-2B Solering Station
+====== JBC HD-2B Solering Station ======
-===
 A heavy duty soldering station modified to work with non-heavy-duty tips.
+{{:infra:tools:img_20251105_175807_622.jpg?direct&400|}}
+Donated by q3k after he bought a bunch from a Kleinanzeigen seller who imported them from some Romanian factory.
+===== Usage =====
+The station warms up fast and also automatically goes to sleep (180 degrees) after a few minutes, then hibernates to be fully off.
+The mounted tip/cartridge is fairly universal for anything from SMD work to dealing with fairly large ground planes.
+You can switch cartridges 'hot', the iron will detect it has been removed and turn off automatically. There's a tool extractor built into the stand.
+===== Accessories =====
+Takes JBC C245xxx tips/cartridges, range available here: https://www.jbctools.com/c245-cartridges-for-t245-handpiece-product-19.html
+Do not buy cheap knockoffs! The legit ones are worth the price.
+Currently available:
+  * C245774 (chisel tip, 1.2mm wide)
+===== Modifications =====
+This was a 48V/T470 station by default, but it has been modified to provide 24V instead. This allows for smaller, C245 series cartridges.
+If you want to use heavy duty C470/48V tips/cartridges, you can modify the station to be switchable between 24/48V - there's a footprint for a DPDT switch on the custom PCB that has been hacked into to it for voltage conversion.
+===== Known Issues =====
+**Open Circuit Error**: Seemingly a firmware bug due to the 24V modification. Put away the tool on the stand, wait for the error to clear, pick up again - the error should clear itself. q3k has started reverse engineering the firmware to fix this issue, but the MCU inside the station is a dsPIC, which does not make the effort fun.
