Ava Y. ★★★★★ Oct 21, 2026

The quartz holds up beautifully on aluminum jobs where my old cups would crack from the heat, and the stubby gas lens gets into tight spots without sacrificing coverage. Hand-made quality is obvious in the fit, and it's become my go-to for high-amp passes.

I've burned through a lot of cups on aluminum jobs, but this lab-grade quartz stubby handles the heat without clouding up. The shorter gas lens profile lets me get into tighter joints than my old setup, and the #8 size gives just the right coverage. Definitely a keeper for high-temp work.

The clarity of the weld puddle through this quartz cup is a game-changer for aluminum work. It handles the heat beautifully without any discoloration, and the fit on my 20 series torch was perfect.
