Note: This cup requires the use of a large diameter gas lens (45V44) to fit #9 & #20 torches or the Furick Torch Mount Kit to fit #17, #18 and #26 torches. If you have one already you can surely use it, but keep in mind that import brands tend to yield lower results.<br><br>The Furick Cup Ceramic Moose Knuckle #14 is constructed just like the tried and true Glass Moose Knuckle #14, but will now be able to handle the accidental bumps and bangs, and best of all you will be able to walk it! The FUPA Ceramic Cup comes with one cup, one spare diffuser and uses anywhere from 25-30+ CFH of argon flow depending on the application. It is recommended for use with 3/32" tungsten and carries a 180 amp rating on constant amperage, which can be increased if using pulse settings. The Moose Knuckle Cup carries Furick's patented double diffuser design for optimum gas coverage. Don't settle for inferior knockoffs!<br><br>The Moose Knuckle Welding Cup is recommended for mild steel, stainless steel, chromoly, titanium, inconel and other space grade alloys. It works best on thinner/smaller applications such as header tubes and chassis tubing.<br><br>Replacement diffuser screens are available! Install these with the cupped screen facing inside cup and push flat side into cup evenly. It may take a few tries to get the screen even. Make sure there is an even gap between the both screens, and that the screen facing the end is tight against the wall of the glass. For foolproof installation be sure to pickup one of the new Furick Cup Diffuser Screen Install Tool.<br><br>It is recommended with all the BIG Diffuser Cups that you start off on low amp settings to stabilize the arc, making sure you will not arc off the diffuser. If diffuser arcing occurs you will have to clean/regrind the tungsten. You will not hurt the diffuser on low amps but if you arc with high amps you can deteriorate the diffuser.
