Just looked it up and N95-P100 masks/respirators cover most exposure that welding should create. I’m a hobbyist welder, but wear a P100 respirator 95% if the time (100% indoors).
From NIOSH:
RESPIRATOR RECOMMENDATIONS
NIOSH
Up to 10 mg/m3:
(APF = 10) Any particulate respirator equipped with an N95, R95, or P95 filter (including N95, R95, and P95 filtering facepieces) except quarter-mask respirators. The following filters may also be used: N99, R99, P99, N100, R100, P100. Click here for information on selection of N, R, or P filters.
(APF = 10) Any supplied-air respirator
Up to 25 mg/m3:
(APF = 25) Any supplied-air respirator operated in a continuous-flow mode
(APF = 25) Any powered, air-purifying respirator with a high-efficiency particulate filter.
Up to 50 mg/m3:
(APF = 50) Any air-purifying, full-facepiece respirator with an N100, R100, or P100 filter. Click here for information on selection of N, R, or P filters.
(APF = 50) Any supplied-air respirator that has a tight-fitting facepiece and is operated in a continuous-flow mode
(APF = 50) Any powered, air-purifying respirator with a tight-fitting facepiece and a high-efficiency particulate filter
(APF = 50) Any self-contained breathing apparatus with a full facepiece
(APF = 50) Any supplied-air respirator with a full facepiece
Up to 500 mg/m3:
(APF = 1000) Any supplied-air respirator operated in a pressure-demand or other positive-pressure mode
Emergency or planned entry into unknown concentrations or IDLH conditions:
(APF = 10,000) Any self-contained breathing apparatus that has a full facepiece and is operated in a pressure-demand or other positive-pressure mode
(APF = 10,000) Any supplied-air respirator that has a full facepiece and is operated in a pressure-demand or other positive-pressure mode in combination with an auxiliary self-contained positive-pressure breathing apparatus
Escape:
(APF = 50) Any air-purifying, full-facepiece respirator with an N100, R100, or P100 filter. Click here for information on selection of N, R, or P filters.
Any appropriate escape-type, self-contained breathing apparatus\
I have literally never seen a welding mask with either a built-in respirator or enough room in front of the mouth/nose to accommodate a separate one. Do such things even exist?
Are you serious? PAPR systems have been around forever. I’ve seen old setups that are fitted to use pressurized air from compressors. Just don’t forget to trap the line or you’re gonna get real oily and moist real fast.
I wear a respirator while welding, but it’s only really a hobby for me so far. But now I’m curious, which filters actually catch manganese?
I’m usually worried about accounting zinc (on galvanized steel), because it can make you ill for a couple days, unless you drink a glass of safety milk.
I know you said you’re just a hobbyist, but a positive air pressure respirator is just the way to go when you’re a welder. It’s basically an over the head setup that works like those old hazmat suits you’d see in movies. It’s got a fan or something blowing in slightly higher pressure air, so none of the air outside can get in as the air is always moving out due to the difference in pressure. What it means is that ALL particulates, gasses, and whatever else you don’t want to breathe have no way to get to you unless it somehow gets into whatever is supplying your air.
They make fanny pack sized units with batteries that are mobile, which works for me as I’ve had to go down in ships and up on scissor lifts to do welding before. I believe they also make slightly bulkier stationary setups that are significantly cheaper but often require other equipment (eg. Specialized compressor) to function. The all in one setup i got is quite expensive (about $2k new) but I managed to find it for quite a bit cheaper used on ebay. I’m comfortable doing this as I’ve been a welder for 15 years and have experience with quite a few different PAPR systems and am confident in my ability to troubleshoot any problems. If you’re completely relying on something like this for safety without really knowing how it works, I’d recommend definitely getting something that comes with a warranty. The parts can be finicky, delicate, and expensive.
And give you a higher chance of getting Parkinson’s from the manganese in the welding fumes.
Just play chess on your free time to balance it oot :^)

I kinda want to know how thick that smoke looks
I think it splits hydrogen off of water molecules too, so if it’s at all humid in there, it might be explosive too.
Only if you don’t wear a respirator to filter that shit

Sorry for your condition, must be hard not being able to do a web search :(
Well where the fuck do you think we live? America. Ain’t nobody getting that shit here.

Good employers will pay for it or provide it, even in the US.
