Hi! these is my first post here, so please be patient! The thing is, my main soldering iron station (a cheap ATTEN937b) despite it works fine, keeps oxidating the tips. I know there is noting bad in it. is just me keeping it on and at high temp all the time. I just dont wanna be turning the F***** knob up and down each time. So i mind a mod. put a magnet in the stand and a reed switch inside the handle rigth were the handle ends. and run the signal using the earth wire. (it short this cable whit one of the 24v ac, i dont use the earth wire inside the unit) my goal is to put the iron on a lower temp setting automatically que left in the stand. these is the board front and back. flipped: https://imgur.com/a/bEnt1mG --- End quote --- --- End quote --- already added a litle relay inside the unit that is activated by the reed switch. i think i should try change the pot resistance value or something but i already try it unsuccessfully.. any help? already have a ts100 that arrived broken and a usb soldering iron that i use now |

Hi! I can say I use such of soldering station over 20 year and I don't have any problems with oxidation of the tip. The tip mist be always clean. When I power of the station I always clean the tip and add a bit of soldering wire to the tip. Jus to keep away the tip from oxygen. My setup of temperature on the unit when it works is between 190c - 240c. I'm not sire does a magnet tip would even trigger the electonic to reduce the current delivered from the mosfet to the heater element. Why? Because the Curie effect if the magnet inside the tip. I tried to understand what you mean under "high temperature". Can you please define on what temperature you soldering? I have also say does I use my soldering station over 20 years and I never changed the heatin element and I use my station frequently every day 5-8h/day. My suggestion would be to setup somehow a switch in the where you put the iron pencil so the switch will trigger some electronic to reduce the current across the mosfet....

You could put in a jiggle switch. A tilt switch that turns on a timer when it’s not activated aka resting. Put this in the handle every time you pick it up it activates the switch solder station heats up. When placed in rest switch not activated, after a period, it times out and reduces iron heat. Of course the drawback is changing iron leads plugs sockets....can you get good silicon wire with enough strands? FWIW... Sent using iPhone |

"My suggestion would be to setup somehow a switch in the where you put the iron pencil so the switch will trigger some electronic to reduce the current across the mosfet...." i already put a switch! is in the handle and is activated bi a magnet in the stand. what i was not able to figure out is how to trigger the electronic inside the unit to reduce the current across the mosfet. |
