Jack It did not add any real weight maybe 2 or 3 ounces at most fans doesn't even make a noticeable difference now the leather snap on to cover my half-bald head is where the weight is. but keeps the sun out and keeps the rays from bouncing back into the hood at night and during bright sunny days

I have a similar one, for the sandblasting hood.

It does take a fair amount of compressed air though.

Once i get it figured out and come up with a super light system for the welding hood ill post results might take me a while cause its still trial and error phase.

Yes but your still drawing the air from right around the helmet.

Right in the smoke plume.....

The professional helmets draw it from a "fanny pack" and also filter it.
