working on a fume extractor myself, but of a bigger scale, kind of like a welding booth about 8' wide, and 3' deep. Other than being on the hokey side and requiring some safety vigilance the vac does work well. Didnt notice any problems w/ it drawing away shielding gases. Plug the power cord into an outlet and test the fan and switch In the summer time a simple fan blowing out a window or even set up in the overhead doorway or entry door would work. That's a great setup you have. It works real good for work I do on the bench but otherwise I'd need an extension or a wheeled unit.
Works great!! The foam "filter" that's used to keep dust out of your computer case will not capture the nastiness that soldering produces.
Thanks Ron. Cut the C13 (computer plug) off of the IEC power cord
Removing the mesh looks like it would improve the airflow a bit.
I made something years ago now.
Bring it back again! Probably a good idea to do that every time I use it since I have the GUV vacuum system in my garage. I have to be honest, I have no idea what it was originally intended for. Shrink Tube
Lassen. I might remove the mesh from the inside grill as you've suggested.
I was stick welding and there was a fair amt of smoke. nice design.
WARNING: This project requires making AC power connections.
But it has very good weather hardening and superior extension cord and 120 volt capabilities.
Been there done that!
You could build a stand for it and you'd be all set.
I think if I put one of these in the middle, 1 above my welding table and 1 above where I got my plasma cutter and vent them all to the same place outside the shope it will work.
But just a box and fan no design I think would have the opposite effect.
If there's no functional reason to have it be that deep, I be inclined to try to build a thinner one and perhaps mount it on a gooseneck or something similar.
Great idea.
Thanks for the comments. 
4 x 2 #8-32 Machine Screws Naturally, I would put it on her side of the garage. When I stick weld it covers the place with smoke. You'll also need a flameproof hose and some kind of funnel and a way to mount it over where you weld (fumes go up, not sideways!).

This setup is for stick welding in the winter when the doors are closed. The Fronius has the ability to feed aluminum with no spool gun but the TIG is not very configurable and the dealer and support network is extremely small.
You might also consider a standard filter in front of the HEPA filter to extend the HEPA filter's lifespan.
This is a solidly built fan, metal and heavy housing. I had a smallish dust collector sitting around and put a sheet metal reducer on one end and ran the other into a chimney. flingwing 1969, thanks, I should have stated my shop is 24x32 insulated, drywalled and has heat. Im happy with how this project turned out. I was looking for something I could just leave up, and would be quieter than a shop vac running.
I opened up the hole and cut the keyway by filing out the extra material.
Pass all four wires out the power switch hole, add shrink tubing to all four wires, and solder in the switch (consult the switch data sheet and/or pin out the switch with a multimeter to ensure a proper connection)
This is definitely a game changer for me.
Just dont know if 200 cfm is enough.
Very nice!
I think the smoke rises but the shielding gas does not. Still very pleased with it. I just wish I was rich and not so handsome!
Glad you found it useful.
Ths is my welding fume extractor which I build a couple of years ago. That does look very good for the budget. Nice job. Make sure everything fits.
Thanks for the quick reply.
Because soldering fumes are composed of both tiny particles and gasses, you need both a HEPA particulate filter as well as an activated carbon filter to neutralize the respective threats.

I drilled my switch hole too far back and it was a bit of a pain to modify the fan, etc. The Everlast has almost no support network and isn't as well polished but you can maybe buy 2-3 of them for the price of 1 of the others.
A big thank you to all of you for your help and advice. Strip the outer insulation off of a sufficient length of the power cord to expose the insulated conductor wires
Mount the fan and the chrome grill on the back lid leaving the nylon lock nut intend for the ground connection loose
In the summer months I work with the doors open, but when it's cold I don't want to lose all the heat.

The inside didn't seem to bad, but I vacuumed it out anyway.
Also, you need to be sure that your airflow is great enough that you're really getting all of the fumes. Unplug the power cord If everything fits and works up to this point, disassemble everything and get ready for paint.
He had hooked the hose to a 3'x3' 6" deep pan over his bench. Paint the parts in a well-ventilated, well lighted, area.
I'll have to ponder that one All times are GMT-6.
Im wanting to get one but Ive heard good and bad about them.
Drawback is pumping your heat out of the building with the smoke. I was hoping at the very least to be able to keep the fans clean by trapping what I could in front of them.
:), 9 years ago I've spent too much time breathing the stuff that emanates from the tips of soldering irons.

Seriously, that's a great idea, but Nice project.
Great idea, I've got a foam insulated shop its extremely air tight. I looked at a Miller but I liked that the Esab came with the Tig setup included.
Realistically, for the hobbyist who isn't soldering all that often, (OSHA inspectors, please skip to the next paragraph) you can probably skip the math for the airflow requirements and just go with "if I can't smell it, it's probably not hurting metoo much." I didnt use anything as big as a stove hood tho. Finding a suitable enclosure was difficult for me. Use one of the Silverstone grills as a template to cut a square of filter material and poke the mounting holes I needed something that was sturdy and with 6" ends on it and the Hammond box was really all I could come up with.
Secure the Silverstone grill with 4, #8-32 wing nuts
Yeah mine came with lids and screws for the lids.
It's pretty loud, and definitely over powered, but it works great and overall the setup for me was pretty cheap.
This is a really nice looking fan, think it's about time I build myself one!
I was thinking of making a hood like a stove range hood only larger (like my table size) but thought maybe it doesn't have to be so big? I just remove the filter from the vac and turn it on and off with a foot switch. Simple and cheap!
Use mask or other precautions. --- RJL ----------------------------------------------.
I hung mine in the garage with modified wire clothes hangers after blowing the dust out the door, and off the parts, with a compressor Right in the center of my "shop" floor I have a drain which is vented to day-light.
My question being if the box came with or without lids? I was searching for something like this for a long time. Theres more than a couple improvements that I could make and more than a few things I could have added at the beginning, but keeping it simple helped get it done. I hung the reducer above the immediate weld area.
Probably not OSHA compliant but neither is any thing about my little basement shop.
Non ducted kitchen fans may have some activated charcoal filters could that work?
I am talking like a foot or 18" stuff. Fan+ motor from an old corn cleaner.
Has anyone made a hood for over their welding table and connected a blower to exhaust welding fumes outside of the building? Look at computer fans which go from around 50mm to over 300mm for the servers cooling, you don't neeed to overdo the suction as many make this mistake and it sucks the shielding gas away, you just need enough suction for it to remove the fumes but not the sheilding gas. You can buy a fume extractor for less than the cost of the enclosure specced here. Stick the self-adhesive rubber feet to the bottom of the enclosure. I fitted a ducted fan to pull fresh air from outside, ducted to where I usually weld but with the ability to be unclipped and directed elsewhere.
1/4 Wire Grommet
nice, what the the blower come from?
Tie a knot in the power cord to prevent it from being pulled out the power cord hole and grommet.
You know, put a cap on it like ya do for a furnace or stove. Does putting a fan into an enclosure produce more airflow? Unless something's changed, Digikey or Hammond owe you two lids.
Clean and remove all dust, oil, and dirt from the surface to be painted. The only detriment that I can see from the reviews is the db levels.
GG, what you have going on there is exactly what I am looking for, for the amount of times I will be doing this.
I have a squirrel cage blower and was looking more into the hood aspect of the DIY project. I thought this machine would be great for nail fume extraction.
Nice. I laughed at it but it was very functional.
Self-Adhesive Rubber Feet. I do not plan to do heavy enough work to flood the whole shop with fumes as I know what I am trying to do will not work.
Makers remorse is always better than buyers remorse. Let me just run that past the wife and see how see likes it. Install the lid/fan assembly, switch, and ground wire
I use it to provide make-up air for the wood stove and the welding hood exhaust. I haven't measured the airflow but it looks like the Silverstone grills are much more restrictive than the chrome grill.

Homer what do you expect to catch with furnace filters other than solid contaminants, i think smoke will go thru with no effect, i know for sure that for paint shops it let the solvent odors thru. Works for me though, doing my little stuff, and much better than looking out the window at the cold and snow wishing it was warm enough to enjoy some welding out there. If itdidn'tturn out that way, at least it would be my loud, expensive, and low air flow fume extractor. I washed down the garage last week and now it should stay clean. Last winter I did a few projects where the amount of smoke and dust in the shop felt unsafe, so I knew I needed something.
if its a freeflow fan reducing size pipe wont improve the suction it will reduce the airflow. I drilled out the original lid holes in the enclosure and tapped them for the thumb screws.

Insert the .25" wire grommet into the power wire hole on the enclosure The subreddit for welders, machinists and all other enthusiasts of joining two things together.
A vent could be run up into the attic and then out the roof.
Mine certainly moves a lot of air. on Step 6, 8 years ago I've spent too much time breathing the stuff that emanates from the tips of soldering irons. WOW great work, how did you cut the 4.5" holes? I noticed that after I was finished welding that the center fan had caught quite a bit of soot on the outside of the grille.
I may be missing it, but what is keeping the arm in place?
IEC Power Cord (Computer Power Cord)
Please give it the diligence it deserves.
Like size and shape. The smoke rises slow enough that it can be directed towards the hose from the suction. This stain relief will protect your connections should the cord get pulled or yanked. Some good points there. 5 years ago, Depends on the shape and of course if there is another port on the enclosure, but yes just look at what a ducted fan can do compared to a regular propeller or even a jet engine for that matter both are shrouded like an enclosure. 4 x 1.5 #8-32 Machine Screws What about venting it through the roof?
nice job! The ones I've seen, the openings have only been like 16x8 tops.
Smart of you to extract the welding fumes at the table level and not suck fumes past the breathing zone.
The chrome grill is on the exhaust side of the fan, but why not?
Thanks for the cheap idea! And sticking a fan at the window just don't work.
Leave enough space to clear the 1.5 thick fan.
I feel compelled to issue a health warning about evil fumes, though. i am using just a simple pc fan with filter from cooking extractor and a grill protector.
I used a .75" .5" shank drill bit which is a little small for the switch.
I'll be starting a new trailer build soon, and with the weather in the 5*F range ain't nobody going to weld with the doors open.
No breeze interference for the shielding gas but good extraction of the fumes?

The reducer was about 8"-10"x6". Thinking about getting a 150 or 200 cfm bathroom fan, ducting outside, and then hang a hose down close to the work area. Perfect size not to big or to small.
Assemble the filter sandwich and install the front lid
Cut a 4.5 hole in the center of each lid, and drill the grill and fan holes

I could taste that crap in my LUNGS, such a bad menthol/chemically taste ugh.
Would recommend for nail industry too!
Now if only I could get my wife to stop parking in my shopthat way I'd have room for a few more tools!
A cheaper enclosure would make this much more of a deal when compared to commercially available models.
I'm tired of the smoke from my welding practice getting all over everything in my garage (not to mention my lungs!).
Layout the holes for the power switch and power cord on the enclosure.
Quick question.
I had a small powder coating business for about 7 years and our powder/paint booth had a series of internal filters in a plenum and a hepa filter system on the top and that worked really well, but it wasn't cheap so I'm guessing that I'm kinda stuck where I am.
I haven't really beat on it yet.
So come on from there!

I could put some lacy stuff around it for her. Reply
good idea now im thinking about building one. Find the center of each lid and layout the locations for the fan and grill mounting holes
Great timing.

Very good.
Pass the cord through the wire grommet from the outside of the enclosure and pull through a good length of cord The filter system may not be as simple as I originally thought. Thanks. Create an account to follow your favorite communities and start taking part in conversations. Rather than struggle with the switch, I ran the power cord that came with the fan out the switch hole so I could power the thing up.
I like well enough.
Thought about a shop vac too, and might have to go that way. The reason I was looking at a bath fan was that I could mount it on the ceiling and leave it there,hard duct it outside, have to fab a new lid on the suction side as I know a tinner, with probably a 4" nipple to hook a flexible hose to get close to my work. I have an attic above the garage.

Between breathing it and using it to clean off resin from my hands when building a boat - OUTSIDE, I ended up in emergency room twice with final in intensive care with chemical poisoning with organs shutting down. Scuff the entire outside surface of the enclosure and lids with Scotch-Bright to help the paint adhere to the surface. The Miller has the easiest process switching but uses funky proprietary TIG hookup and lacks some configurability and hardening against the elements of the ESAB.
It was a close call.
Did you make this project?

Sure. I put some chassis grease on the joints and snugged them up good. Looks good, and for $70 your a fraction of a pre made setup. You must log in or register to reply here.
Im looking forward to see it in stock again. The picture shows lids to accompany the box, but mine arrived without lids.

That's it. 8 years ago That looks like it should work nicely. How about something with a wider mouth feeding into the flex?

The enclosure was by far the most expensive part in this.
