FUPA 13 螺紋玻璃杯，#FUPA13

The threaded brass insert is a game changer—no more worrying about lost orings. The argon flow sits right at 35 CFH with the diffuser, and it holds 175 DC like a champ. Fit my downstem perfectly, solid purchase.

The threaded brass insert is a game changer—no more fumbling with o-rings that always seem to roll under the bench. With the 3/32 diffuser and that 175 DC rating, this cup handles my argon flow at 35 CFH like a champ.

The 3/32 diffuser on this cup gives a perfect, concentrated arc for tight TIG welds. I’m getting way better gas coverage without blowing out my puddle compared to my old setup.
