Soldering station with fume collector

I was searching something to collects  fumes from  from soldering but i couldn’t find something in a reasonable price. So, i begin to construct it and after a many practicing is now finished. It is a cheap soldering iron  with a P.I.D controller along a pump for fumes. Let’s begin with the soldering iron . It is  Hakko clone at 24V AC. Hakko has already a thermistor inside the ceramic resistor but it’s resistance is especially calculated for a specific circuit. I abolish it, and i connect my P.I.D.soldering iron  So ,i use just  two wires for the resistance. Fumes are collected with this blank metal bar.  It should be cut off at this shape for a better performanceIMG_1476 (Custom)  Next hard step is to secure the metal on the base of the soldering .

i use thisteflon that is special for high temperature applications and I tire up it an the body of soldering

Afterwards , secure the small rubber tube , and the switch that i ‘ll use to operate the pumper.

Next ,we have to take care the filter. It is a big deal to find the best solution ,as more as you are looking for a right filter ,you may have better results. In my project, i use a air filter from pumps in aquariums , i take of the rubber that was inside for the air and i place a small piece form an aquarium filter .Air ,pass through without any problem ,but the main point is that it need to be cleaned very often. I have not found any other solution. I secure this with tube shrink

And it’s finished,with the thermocouple placed on the soldering iron

Now move to main part . You can see here the transformer 17 Vac. This soldring iron need 24-25 volt Ac ,but i use 24 Dc. You can see the bridge rectifier and the smoothing capacitor. Down left is PID controller and here is the manual

This part here is easy ,i made all the connections , I power up the pump 12 V Dc ,the controller with 230 V and everything works fine
