In this video I show the cheap way to build a welding fume extractor, to get rid of unhealthy smoke. Thanks for watching, please like comment, and subscribe.
Seriously folks, use ventilators and respirators. Metal particulates and metal/gas fumes are the final realm of safety welding culture is finally catching up on. Many long-term illness and diseases associated with welding mostly come from the inhaling of these. I work at a millwright company and most of the old-timer metal fab/welders I know have some form of chronic disease that could possibly be tied to metal fumes. COPD, Parkinson's like symptoms, tremors, etc.
Great Job Sir!! I need to know where you got the flex hose. I use the aluminium flex and it tore out after use. what you have there looks a little heavier gauge.
I try to stay away from looking over the weld, so the smoke doesn't rise in my face. Also, If I am welding on galvanized or paint, I wear a respirator. Thanks for commenting!
The problem with a filter is it will reduce airflow significantly. Whether how much it reduces the airflow makes it ineffective or not is up to the user but generally speaking the better the filter the more it reduces airflow. Those exhaust fans are generally built with loose tolerances and sealed bearings to withstand gumming up and it could be years if ever before it does gums up. One thing you could do to prevent it from gumming up and get it off your mind is to spray the inlet side, outlet side and fan blades with a lubricating silicone spray that will dry and create a film that will resist anything sticking to it. You could take that one section apart every six months to a year, depending on how often you use it, to clean the fan and reapply the silicone.
He's not using flame welding. Arc welding is not likely to ever cause a bench like that to suddenly burst into flame. He'll probably get burn marks but with the fairly cheap lumber top on that bench that be flipped at least once or sanded down before needing to be replaced for about three and a half bucks it's not something I would worry about either. A metal top with arc welding is more about the seeming convenience of being able to clip your ground anywhere on the table top instead of the work piece. I say seeming convenience because in reality you should be clipping to the work piece no more than a foot away from where you're welding or your weld will suffer. The cost of a sheet of metal large enough to cover that bench for the sake of saving a few burn marks or slag speckles is likely not worth it for occasional use - especially if you need to use the bench for other things as well that are better done on a wooden bench.

Nicely played. I want one of those for when I need to use my everlast welder indoors.

No doubt for someone with a career you want to take all of the precautions, but I think this is more for the occasional backyard welder.
cool idea, thanks :) what's the power of the fan ?
Nice, thanks for this video.

I think if you would talk your subs would increase most people don’t care for this style of video even though your editing is good
How do you prevent welding fumes from crawling around your helmet and hanging out around your face

How much did that overall cost
Great idea! Thanks
Great idea! Do you find the fan gets all gummed without a filter?
Not yet it seems to be working just fine, I might add a filter in the future.

Nice job.
nice. now step 2 is making a metal top for your workbench before you set it on fire

Nice diy
Cheers
where did you get the fan unit?
I bought the fan used at a tool auction. But there are similar ones on ebay. Thanks for commenting.
I was thinking of using something like this
