From time to time, I need to break out my soldering gun and repair various electrical bits. I do this in my garage with the door open and a fan on, because the smoke and fumes from the melting solder makes me gag and cough for days.
Years ago I saw a photo of a device that collected the smoke/fumes and, I assume, pulled it out of the building. The part I remember looked like a squarish funnel perched on the bench directly behind where the worker was soldering. The smoke would therefore be sucked directly into the funnel.
What are these vacuum things called? I’ve spent half an hour googling, and have come up with squat. I’ve found some dust collection devices designed for woodworkers, but that’s not what I have in mind. Maybe it was just a specialized funnel doohickey that clamped on the end of some sort of traditional vacuum system, but I doubt it. But who knows. I certainly don’t, and would like to find one of these devices.
