TIG Gas Nozzles, Cups, Trailing & Auxiliary 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.

Material types to choose from:

  • Pink gas nozzles are the most popular general purpose TIG cups. They are made from high-temperature thermal shock-resistant alumina oxide.
  • 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 exclusive Monster nozzle, Vortex nozzle and Gas Saver cups and are made from pink alumina, hard anodized aluminum or glass with composite diffusers or screens. 
     
  • 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.
