Laminar Flow EDGE® XXL gas lens Pyrex cup for 9 and 20 Series TIG torches. Available in the following sizes: #4, #5, #6, #7, and #8. Sold individually. Each cup measures 3" x 1" x 0.75". This is considered the elite gas coverage, with its newly updated shape and gas lens screen. There’s nothing else in the industry that gives the gas coverage that these do. Works with a 9/20 Series gas lens, as well as with a 17/18 Series stubby gas lens when used with P/N GL920-A (not included).
All EDGE cups, 20, 25 torches, are hand-made in the USA. Each cup is made out of laboratory-grade borosilicate glass, most commonly known as Pyrex.
EDGE Welding Supply Laminar Cup Recommendations:
♦ The EDGE adapter and EDGE cup must be fully seated onto the Teflon heat/thermal shield.
♦ For use with DC only and up to 180A unless using pulse settings.
♦ Best used with metals such as Stainless Steel, Titanium, and Inconel.
♦ The #10 EDGE Pyrex cup can be used to weld aluminum based material, but only in short runs.
♦ Can be used with any size and type of tungsten.
♦ The 'walking the cup' technique is not recommended with Pyrex cups (walking the cup causes premature cup failure).
