If you want better visibility with a standard lens welding hood, just
buy a $10 quartz, 300 watt, flood/work light at a hardware store.

Just point it at your work and you will be able to see when you aren't
welding.

Ernie recommended this some years ago, and thats exactly what I did.

Works a treat!!

Jackson and Speedglass both offer good products. But wait for
Gunner to check in on this. Harbor Freight offers several autodarks,
some of which are undoubtedly crap but several have found one or two
of them to be quite acceptable.

I have a Jackson EQC bought years ago. I had occasion to try another
guy's Jackson NextGen. I didn't like it as well as the EQC and
wouldn't trade.

Variable shade is important with TIG if you'll use a range of welding
currents. Ya can't weld well if ya can't see the puddle, and ya
can't see the puddle if it is either too bright or too dark.
