TIG Gas Nozzles
, Cups & Trail Shields
The World's Largest Selection of TIG Gas Nozzles, Trail Shields & Flooding Cups
Choose the best nozzle, or purge gas shield for your application and budget. Arc-Zone delivers the world's largest selection of high-quality TIG/GTAW gas nozzles. The gas outlet or "orifice" of a TIG nozzle/cup is engineered to maximize gas flow around the tungsten electrode, and provide a smooth and consistent argon/helium shield around your weld bead. TIG gas nozzles are measured in 1/16" (1.6mm) increments. For example, if your gas cup is marked with a #4, that means it's a 1/4", (6.4mm) or 4/16" in diameter.
Pink gas nozzles are the most popular general purpose TIG cups. Made from our premium "ZTA" Zirconia Toughened Alumina™ oxide for high-temperature applications and they are thermal shock-resistant.
Quartz or Pyrex glass nozzles are used on micro TIG and other specialty applications. They offer improved visibility and are extremely temperature resistant.
Grey [Super Cups" are engineered for high amperage AC applications. They are made from ultra-high temperature Silicon Nitride material and are virtually thermal shock-proof.
Light Brown gas nozzles are for specialty or high-reflective heat applications. They are made from high temperature lava ceramic and can be used where special shapes are needed.
Flooding cups deliver the performance and versatility that every serious TIG welder needs! They include Arc-Zone's complete range of Monster™ nozzles and Gas Saver™ cups and are made from engineered materials designed to improve shield gas coverage and reduce weld impurities.
High-Purity Auxiliary and Ultimate Trailing Shields are engineered for the most demanding precision TIG and PAW applications. They are designed to distribute gas with high-tech diffusers and are made from hard anodized aluminum.
