20 Series Gas Nozzles
TIG/GTAW, HeliArc, or HeliWeld gas nozzles, or gas cups are available in a variety of shapes and sizes depending on your torch and welding application. The gas outlet or "orifice" of a TIG gas nozzle is measured in 1/16” (1.6mm) increments. For example a #4, is 1/4”, (6.4mm).
- Pink Alumina Oxide gas nozzles are the most popular TIG cups. They are made from high-temperature shock-resistant alumina oxide.
- Lava, light brown gas nozzles are machined to size then fired like pottery to give them strength. Lava gas cups are used for high-reflective heat applications. Lava nozzles can be machined to a variety of shapes and sizes.
