Our Welding Cups Look a Little Different.

Don’t get us wrong, we’re fans of the pink cups, too. We simply provide an alternative to what’s out there by producing welding cups made from glass – enabling you to see your weld as you go.

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.

SEE THE DIFFERENCE

With over 25 years of glassblowing experience, our products are guaranteed to withstand the toughest jobs and environments.

If we don’t have a standard cup in production that meets your needs, we can create a custom cup for your application.

Reliability & Durability

Edge Welding Cups are designed to withstand the harshest environments and treatment.

Fast & Easy Assembly

One advantage with Edge Welding Cups is the speed and ease in which you can assemble your welding torch setup.

Fast & Easy Disassembly

Disassembly is just as quick and easy, allowing you to switch cups, as needed, with minimal downtime between welds.

Every welder has said to himself at one time or another, “I wish I could see what I was welding – while I’m welding!” It takes tremendous practice and concentration to develop the senses that compensate while using traditional ceramic welding cups.

I was very pleased to discover EDGE welding cups. They are exactly what welders need to learn better and faster while practicing their skill. Especially useful for those hard to see angles that make a job extra challenging. EDGE welding cups are a valuable tool for any welder. Edge has always proved excellent customer service and they are always willing to work on providing a product that will fit any specific application that you may have.
