Have you got some more details of what and where from please?Iring on a WP9 torch. made some up from the pyrex tubes used in some of those cigarette substitute puffy smoky things, With the help of heat residing "O"
I'm curious that you're having issues getting them off. I've had them fall off with wrong size o ring. Using the wrong material o ring might cause the glass to fuse on. Can't use the standard ones. I look through the pyrex to weld.I have a set, Im not convinced the extra light/visibility is helpful, but I found they can be a pain to get off. I generally use alumina ones instead now.
6s on a wp17 torch, without lens. Although I have a wide range of them, which I never use. I find using the perspex I didn't touch anywhere near as much as with the ceramics. Again it's all down to the individual....but for me a game changer. The other plus IS the advanced AC TIG which is brilliant at low amps. None of my results could be classed as exemplary. But never welded for a living, more of an aside to it. Fusing thermocouples etc...What were you using before these, and what size cups?
I'm on a no7 standard wp20 gas lens for nearly everything, i tried those but I didn't like the O ring seal, and they don't like lots of AC heat. So decided to stay with alumina screw on cups.
I found that those bigger cups liked more gas, though. Just my experience.
The pyrex ones are pretty robust. Don't break easily. Don't know anything about the e-ciggy ones.I tried using the glass parts from e cigarettes, trouble is you only need to look at them for them to shatter, the ceramic ones are bulletproof in comparison. if you're clumsy like me, you'll need to stock up on the glass bits
With two of the green orings, I imagine they swelled with heat. It would rotate but not pull off, didnt matter how much I wiggled it in every direction. Did eventually get it off perhaps 6 days after I first wanted to.I'm curious that you're having issues getting them off. I've had them fall off with wrong size o ring.

I ended up with a few for that by accident. Tried to mod them...failedI just measured up the WP9 torch, looked on Ebay for the pyrex tubes, quite af ew size available, and found 'O' rings to suit, I will see if I can find a photograph

Yeee Dawgeee! Just stewed up a mess of grits........I think to a lot of users they are more an image thing than actually any real benefit over a quid a piece standard pink cup.
Maybe some people can see and weld through them but I can’t bloody do it as it’s just a horribly distorted view
Hideously expensive if you buy the real welding ones and I’ve had them in the past and used them for their actual intended purposes on the very rare occasion I had something that would lend itself to them.
It’s very fashionable in the states to have a big clear tig cup, have a nick name like “Tdawg” and wear a Tee shirt with “my other ride is yer mom” on the back
I did a tiny tig weld and looking through the cup was the only way. The gas lense is the other part of the equation which I also didn't have before.Might try one at some point for going into corners etc, I've recently switched back to a gas lenz on aluminium at home for some reason a standard cup was messing with the tungsten tip, not discolouration, just not balling right
