Comes with 1 full cup, spare diffuser and o-rings for mounting
The BBW cup is a DC polarity only cup and is to be used with a 3/32 – 2.4mm tungsten only. It has an inner diameter of 1.060 inches/ 26.7mm and will need 30 CFH of argon flow. It has an amperage rating of 200 amps. It is the biggest Furick Cup and is used for welding bigger, thicker, rounder applications. It is great for Stainless Steel, Inconel and Titanium but if you are welding smaller tubing in any of those materials choose a Fupa #12 Cup or the Moose Knuckle #14 Cup. I do not Suggest “ Walking the cup” with any of the Furickcups due to the nature of the Borosilicate laboratory grade glass they are constructed of.
If you have a #17, #18 or #26 size torch you will need a #17 kit ,
If you have a #9 or #20 torch you will need to have a 45V44 gas lens, If you have one already, you can surly use it, Keep in mind that import brands yield lower results.
BBW is recommended for, Stainless steel, Titanium, Inconel and other space grade alloys . It works best on thicker / larger applications where you need spread out coverage.
It is recommended with all the BIG Diffuser cups that the user start off on low amps to stabilize the arc as to make sure you will not arc off diffuser. If diffuser arcing occurs you will have to clean/regrind the tungsten. You will not hurt the diffuser on low amps but if arc with high amps you can deteriorate the diffuser. Also be careful not to drop or hit cups against hard objects being we all know the nature of glass.
