In Tig welding. Most persons forgets the ozone. That's poison to your lungs, more harmfull in long run than tungsten. ( Overall dose is creater )

I have seen people welding with tig without respirator, and putting it on when grinding electrodes... Much better to use it all the time. Specially in workshops without extra good ventilation.

I succest to get motorized respirator with suitable mask.
Those are much comfortable in use.

In Europe Esab sells good kits with a fair price. I personally have 3M adflo with speedglass mask, but those are little pricey.
