EDGE Gas Lens Quartz Series

Featuring a unique design with an enhanced profile and integrated diffuser, these cups deliver turbulence-free laminar flow, ensuring exceptional gas coverage for DC TIG welding with up to 75mm of tungsten projection.

Each cup is meticulously hand-crafted in the USA from laboratory-grade borosilicate glass, then oven-annealed to maximize durability and longevity.

All cups are clearly labeled for easy identification and come with a stainless steel diffuser.

The maximum DC rating is 180A, unless using pulse settings. For AC welding, only use #10 or #12 cups with low duty cycle. Cup walking can reduce the lifespan of the cups.
