EDGE 920 welding cups are hand-made in the USA. Each cup is made out of laboratory-grade borosilicate glass, most commonly known as Pyrex.

EDGE Shorty Series for the Gas Lens 920 Series is a great option for better gas coverage and smaller areas that still require the larger cups!

EDGE Shorty Series is available in a 10, 12 with diffuser, 15 with diffuser and an 18 with diffuser

Guidelines to get started…

EDGE ADAPTER AND EDGE CUP MUST BE FULLY SEATED ONTO THE TEFLON HEAT SHIELD FOR SAFETY PROPER GAS FLOW.

GL920, GL1718, CB920. CB1718 (P4-10)

*We recommend DC only, 180 amp unless using pulse settings.

*Can be used with any size and type electrode.

*Best used with metals such as Stainless steel, Titanium and Inconel.

*Aluminum based material should use with #10 or #12 in shorter runs

*We do not recommend walking the cup with Pyrex glass cup. (This will cause premature failure)

GL920-P12, GL920-P15 AND GL920-18

*We recommend DC only, 180 amp unless using pulse settings.

*Best used with metals such as: Stainless steel, Titanium, Inconel,Nickel based & thin aluminum based.

*Recommended use with 1/8, 3/32 and 1/16 (2.4) electrode. 1/16 diffuser must not exceed 90A DC because of potential

damage to diffuser.

*The tungsten can be extended up to 3” out in controlled environment for clearance.

*We do not recommend walking the Pyrex glass cup. (This will cause premature failure.)

GL920 QUARTZ CUPS

*Can be used with any metals

*We recommend DC only up to 350A

*Can be used with any size tungsten unless using diffuser technology.

*All sizes of cups can be used with EDGE diffuser technology.
