Serious about your TIG welding? This Furick FUPA #12 kit is a game-changer for gas coverage and visibility. You get both a glass and ceramic cup, plus a titanium cover that slips over the glass for protection against bumps. The patented double diffuser design gives you amazing gas coverage - we're talking 25-30+ CFH argon flow depending on your setup. Rated for 180 amps constant (more with pulse), it works great with 3/32\\\ tungsten. Perfect for mild steel, stainless, chromoly, titanium, and even space-grade alloys on thinner applications like header tubes or chassis work. Made in the USA from lab-grade borosilicate glass, the quality is obvious. Comes with spare o-rings and a diffuser too. Note: You'll need a large diameter gas lens (45V44) for #9/#20 torches, or the Furick Torch Mount Kit for #17/18/26 torches. Don't walk the cup with the glass version - save that for the ceramic. If you want superior welds with incredible visibility, this is your setup!
