What's the deal with clear tig cups?

[Brian Ski]

I used the clear cups with a gas lens - best of both worlds!!

Don't hold us in suspense... Do they get dirty fast??? Do you have to clean them often??? Have you had trouble with any breaking??? Do you use them a lot??? (for a lot of welding???)

Interesting... I hadn't seen those before (new to TIG). Here are some related links:

They work well for a while then the Pyrex lenses start to turn milky white from the heat so they need to be cleaned frequently and will break easily since they're glass. They have two different diameters available and the larger size gas lens kit allows you to protrude the tungsten out further for improved visibility.

Cool.. Looks like they have their purpose. They're more expensive than I figured. Will probably start with standard and try a clear one sometime later
