8-4064 - Thermal Arc #8 Gas Lens Alumina Cup (1/2 Inch)

Get Cleaner Welds with the Thermal Arc #8 Gas Lens Cup

If you are looking to step up your TIG welding game, switching to a gas lens setup with the Thermal Arc 8-4064 Shield Cup is one of the best upgrades you can make. This #8 alumina cup is designed to work with a gas lens to smooth out your argon flow, turning a turbulent blast of gas into a soft, steady stream. Why does that matter? Because a smoother flow means you can extend your tungsten further out of the cup—sometimes up to an inch—without losing shielding coverage. This gives you incredible visibility of the puddle, allowing you to weld in tight corners or deep grooves where a standard cup would leave you blind.

The #8 size (1/2 inch) is the perfect "daily driver" size for most TIG applications. It provides a wide enough umbrella of gas to keep your stainless steel colorful and your aluminum clean, but it isn't so bulky that it gets in the way. Made from durable pink alumina ceramic, this cup handles the heat of high-amperage welding without crumbling or cracking easily. Whether you are walking the cup on pipe or dabbing filler on a precision bracket, the consistent performance of this nozzle helps you lay down those stack-of-dimes beads everyone admires.

Stop fighting turbulence and porosity. By using the Thermal Arc 8-4064, you ensure that your shielding gas does exactly what it's supposed to do: protect the weld. This cup is a genuine replacement for Thermal Arc torches and fits securely onto your gas lens collet body. It’s an essential consumable for any welder who takes pride in the appearance and quality of their work. Keep a few in your kit so you are never caught with a cracked cup in the middle of a critical job.
