Furick FUPA #12 Glass Cup

Furick FUPA #12 Glass Cup Kit

Introducing the legendary Furick FUPA #12, the patented masterpiece that's handcrafted in the USA using Borosilicate laboratory grade glass. With an inside diameter of .750 inches/ 19mm, this baby is recommended for DC polarity applications only, making it ideal for mild steel, stainless steel, chromoly, titanium, inconel, and other space-grade alloys.

This bad boy is designed for 3/32 / 2.4mm tungsten size and boasts a 180 amp rating on constant amperage. And if you're using pulse settings, you can go even higher! But, due to the delicate nature of the glass, "walking the Cup" is not suggested.

To ensure optimal performance, it's recommended to use 20-30+ CFH of Argon flow with the FUPA #12. It works best on thinner/smaller applications such as header tubes and chassis tubing. Keep the diffuser in its original shape, and if it gets out of shape, remove and reinstall it.

But wait, there's more! With all the BIG Diffuser cups, it's best to start off on low amps to stabilize the arc, so you don't arc off the diffuser. And if diffuser arcing occurs, you'll have to clean/regrind the tungsten. Low amps won't hurt the diffuser, but high amps can deteriorate it, so be mindful. Lastly, make sure not to drop or hit the cup against hard objects. We all know the nature of glass!
