Face Mask?
Does anyone wear a face mask whilst TIG welding? I seem to find myself a bit light headed and get a bit of a headache after doing a bit and wondered
what other people do. Besides that what would type would fit under a welding mask? An extractor would suck away the argon if I had one.

But the shielding gas would be sucked away ^

Is the lenses you are using the correct shade...

I think just generally good ventilation. Extraction wont take the sheild away as the shroud will create the correct shield.

What are you welding to get light headed, I've found tig to be relatively fume free and there's nothing in steel or aluminium to cause it.
You aren't holding your breath while welding are you ?

I went into the RSPCA office the other day. It was so small you could hardly swing a cat in there.

Check your helmet is suitable for TIG. Not all of them are

What helmet are you using the wrong shade could make your eyes go funny which will do your head in.

If you're using Argon gas then that has a sneaky trick... it's slightly heavier than air, and accumulates in areas where the ventilation
is poor. If you end up trying to breathe in that atmosphere then you won't be getting enough oxygen, but your body doesn't know it -
it's designed to react when CO2 gets too high. If you're REALLY unlucky then you're upright one minute and keel over the next -
your body thinks that it's breathing proper air...

I'm not welding any galv and I don't have the welding or argon running long enough to fill the garage up .
It's funy that masks are mentioned as its something I was suspicious of. I have an SWP 9-13 auto dimming mask same as this one
here (actually wished I'd have bought it from here now!) I've just had
a look at the settings and I've had it at around 10-11 with a 3/4 sensitivity setting. Either way it's nowhere near as dark as my mig
mask. You can't see anything until the arc is struck with that which is when you generally find you're in the wrong spot!
Perhaps it's the mask settings then?

You need shade 13 for TIG

If its fumes (and as above, it may well be light induced) you can't block fumes easily with a mask, as they are mostly particulate rated. You
would need an activated charcoal respirator, like the ones for use with paint / organic solvents... or ideally a forced air one integrated into the
mask like this...

PS - I know a lot about exposure to gases, but little about welding, though I can mig a bit!

What amps are you using ? That is a sweeping statement, you need less shade for lower amps.
