Weller VP 801 EC

Weller VP 801 EC

It's time for another look into an electronic device: This time it it is a Weller VP 801 EC desoldering station. I recently acquired one of those old professional desoldering stations. They are used to remove solder from e.g. PCBs in case something is wrong and needs to be replaced. Essentially, they are an expensive variant of using a soldering iron with a vacuum plunger, or solder wick.
Notably, it has two equal transformers, is based on a SL443A (controller), LM358AM (op amp), T0609DH (triac), BTB06-400S (another triac). I guess one transformer and one triac are for the pump while the other ICs control the heating part. It is very well built, easy to open and service. This one was built in 1985 - the main PCB module has a marking of 06/85.

  3. Thank you for posting this. It may help me fix my unit where the pump and heating element seem to have become shorted together....
