The FUPA#12 is one of the most economic specialty TIG cups there is.
The inside diameter is 3/4” (19mm), but the unique diffuser design provides better coverage than most other cups.
This cup uses only 12-30CFH of argon and most jobs go well with around 20cfh… that's about the same gas flow needed for a #8 cup.
Currently, the Fupa 12 designed for use with 3/32" electrodes only. It's not for AC since the diffuser can arc out, and 175 amps is the upper limit.
When you need great gas shielding or a really long stickout or both, the Fupa 12 fits the bill.
The FUPA 12 Kit comes with 2 cups and 2 diffusers and will fit all existing 9/20 style 2.4mm (3/32) gas lenses.
They can also fit WP17/18 and 26 torches but you will need to purchase the FURICK17 adapter kit for this to work.
