Weldtec/TEC introduced the glass nozzle to TIG torches back in 1955. The original nozzles were made from Pyrex grade glass. These new modern fused quartz nozzles offer superior temperature and thermal shock resistance, surpassing Pyrex, lava, and the pink ceramic nozzles for performance. Now you can use these quartz nozzles on most TIG torches using a simple adapter ring (10NQA for air-cooled & 13NQA-2 for water-cooled). Available in several orifice sizes and several lengths to suit your job requirements. Made in the USA.

These Quartz Nozzles are not compatible with standard gas lens'. They require 45VXXNQ Gas Lens'. Please contact us for pricing and availability.

• Better weld puddle visibility
• Higher heat resistance
• No thermal shock breakage

Improves visibility. 4 I use this cup on a 9 torch with collet adapter. Great Visibility. It is a blessing and a curse with this cup you can see so well. It is easier to keep welding into a bad torch angle that a alumina cup would block your view and make you stop and reposition. Since it is a press on fit to your torch, you must also make sure that it is concentric to the tungsten. If you prop the cup with any pressure the nozzle will "tip" and not be centered around tungsten. I get better welds now that I can really see the puddle so this nozzle is good for me. Pros: Great Visibility Used adapter ring with my traditional collet body. Great service, fast shipping from IOC. Cons: No propping cup. Must purchase adapter ring for collet or gas lense with O rings. I suspect a you could find O rings to put on your own gas lense. Price! Too expensive. Quartz glass rod in this size would get you few feet for the price. But then you would need the skill of a glass worker to make these things.
