    I am soldering with colophony flux and solder with lead.

    How dangerous is such soldering in the house ? I am concerned about the fumes (I wear gloves when touching elements with lead).

    Do I need to wear gas mask or something?

    I can’t open the window in the winter and don’t want to make a hole in the wall for ventilation (I have new thermal insulation and don’t want to mess it up).


    I once worked for an electronics manufacturer and all soldering stations had fume extractors. There is a difference between soldering for a living and soldering for hobby. I suppose that gentle ventilation for hobby works is good enough.

    Be careful with ventilation because too much wind will cool the part you’re trying to solder.


    I am wearing eye protection when I solder. Also I am using proper ventilation (fume extractor). Because breathing fumes from soldering with colophony may bring you asthma.
