A welding respirator is really needed when welding thru "weld thru primer", it is full of zinc (upwards of 95%) and is very dangerous. A fan is a big help but a respirator is also needed.

I welded my front corner in today. Now you can see how it fits together.

After



Here is a picture of the assembly welded in place,



To finish installing it I need to gently heat the top support around the edges with my O/A torch. Once it is cherry red It will be soft enough to gently tap it down to provide a tight fit with the floor pan. When that is welded around the outer and inner circumferance this mount should be as strong as it ever was.

I LOVE this thread!

foil air dam

sometimes you can use aluminum foil or the foil tape air condition installers use on duct work to make an air dam around the weld area to keep the shielding gas in place while using a fan to have a safe breathing zone

I did not know there was a welding respirator. Learn something every day.

I use a disposable one because the others won't fit in my Cherokee helmet. PPE - Respiratory Protection | Disposable Respirators | 3M 8214 N95 Particulate Respirator w/ Face Seal, 10/Box | 652625 - GlobalIndustrial.com

Do get one John, I have heard a few horror stories. A fellow on another site almost died from one welding job where he installed a rad support on a Honda while it was stuck in a corner on the frame rack. They found him unconscious laying on the floor! He spent a week in ICU and is forever damaged with a stint in his chest to self administer shots of steroids into his lungs. Zinc fume fever is REAL and very dangerous. I'm sorry I didn't mention this earlier looking at your progress is so damn much fun I forgot to preach as I usually do about safety.

I think most people will find a welding respirator is an expensive item, and unless you were doing a ton of welding on galvanized metal, not necessary. The smoke that comes off is easily dealt with by having the fan blowing at you, and not the material being welded. It keeps any smoke away before it can reach the person who's welding.
I also hit the areas I'm going to weld on with a grinder to get some of the galvanizing off before welding. Probably not necessary on spray galvanizing, but with hot dipped it's pretty thick, and doesn't weld well if I don't remove some.
I used all galvanized EMT on the framework of my tilt frontend, and with a fan I had no problems, and never have had previously.

My health is well worth the $20! I am not kidding, Eric, the guy I mentioned, his life changed forever with one job, done deal, his lungs are destroyed. This happen when he was 23 as I remember. But when we will spend $20 for a burger and a beer, I think it's good money spent.

Fans help, and "could" be enough if used properly, but we move around, we forget. Doing something like Johns floor, he is stuffed inside of a "bowl" welding on the bottom, the fumes (Fumes are tiny pieces of the burnt material in the air that we are breathing, read that zinc, we are actually breathing the zinc) are filling the "Bowl" and it is very hard to get it all out before we breath it. It's like AIDS, it never bothered Freddy Mercury or Rock Hudson, until that one time............

I don't want Johns great thread to be taken over by my preaching that darn old health stuff so I won't anymore. Enough has been said from me.

Brian

I didn't realize they'd gotten that cheap ($20) Last time I looked at them the canisters were almost $80 a pair. At $20 they're too cheap not to use. Where did you see them for $20? The link you attached says $72.

I'm a "fan" of pretty much everything you post Brian, and if you think I could help...let me know, I'll help....LOL

Seriously, I do agree, many of us had welder's flash...it burns the eye's something crazy the next day...we learn and religiously wear a welding helmet after. Unfortunately, as Brian mentioned, you may not always get a second chance with the off gasses that you get when you weld.

$20.00 is pretty cheap insurance...and what kind of place charges $20.00 for a burger and a beer....up here in Canada we can buy a dozen beer (depending on brand) and still have enough money left for a pound of hamburger...LOL

Good info guys. I have welded galvanized metal and indeed it is nasty stuff. This weld-thru primer does not give off the smoke or fumes the metal does and I had not given it a second thought. I will be cautious as I go forward though. The Zinc probably gives off at least a limited amount of fumes.

That's for a box of TEN! And internet deal for sure, at my local hardware store they are about $20.

I wear the same half-face respirator when I weld as I do for light painting. I can just barely fit my helmet down over it. If I don't wear it when I weld, I get a headache, and it doesn't take very much.

If John does any painting, which I know he does, then he's already got the equipment to keep himself safe while he welds.
