Respirator for welding galvanized steel

TomChimera · Thu Jun 20, 2019 2:47 am

Hello everybody,
Thank you for great forum!

I have an upcoming project I will be welding galvanized steel (outdoors)

After having the fever twice in the past I'm looking for a good mask,

I will be honest, here in Israel I almost never see a welder wearing a mask, maybe the cigarette smoke is protecting them..
Also getting a good mask is not easy, so I will order from Amazon

I heard many people use the 3M P100 filter with a half facepiece respirator, but I thought wouldn't it be better bundled with a cartridge?

Like the 3M 60926

If so, can you recommend which cartridge is the all-around "best"? There's so many options..

Any advice is very welcome,

Thank you

Tom

Hi there,

3m is the best company to go for, and you should be able find on Amazon. The ingredient in galvanised steel is primarily zinc. So look at this guide and have a look. Don't forget, you are looking for protection from thermally generated particles.

Thanks Mike for your answer!
I'm going through the pdf guide but having a bit difficulty understanding it, (I'm not a native English speaker)

Can you guide me to specific products you recommend?

I can't find the words zinc or thermally generated in the pdf

Thanks!

Those cartridges are great, but they won't fit under most welding helmets once you put on that respirator. As such, we are limited to the pancake style filters for half-mask respirators. Now if you could build something like those "PAPR" systems, then that free's up your choices for the filter element since it is no longer within the constraints of the space between your face and the helmet.

Hi,

Sorry for confusing you. This type of respirator and filter is perfect for welding and grinding zinc. I wear one at home.

Thank you for your help!

I got the respirator, fume cartridge + P100 dust filter and it fits perfectly under the welding mask!

Thanks

Seems my horse was too slow but the Miller underhood mask works awesome, I use it a lot.... okay sometimes.

But It's treated me well.

Does the Miller one let the lens get foggy due to the exhale exhaust venting straight out and not down?

Doesen't do that to me, but I guess it depends if you breathe heard.

It's not so much that I breath hard, it's just that I sweat a lot so the evaporation of sweat combined with normal breathing sometimes tends to get in the way. Unless it's a nice dry day outside with little humidity.
