1The name ‘Nozzle’ is sometimes used for the TIG gas nozzle.

Gas cups come in a variety of sizes, dependant on the amount of shielding gas required around the Tungsten electrode, (the size of electrode, the material and the current you’re using). The physical space to position the TIG torch (and the ceramic cup) can also be a factor.

Types of TIG Gas Cups:

Ceramic Cups:

The majority of the ceramic cups you see are ‘Pink’ made from Zirconia and alumina. You can get gas cups made from other materials that have slightly different properties:

Types of Ceramic Cups:

Ceramic Cups – Pink (Zirconia & Alumina):

The cheap and cheerful ‘pink’ gas cups are made for general, everyday use. If generating a large amount of heat (high amperage), then they can break after prolonged use.

Ceramic Cups – Light Brown (Lava & Alumina):

For higher temperature TIG welding. Generally available from more specialist suppliers.

High Temperature Cups – Grey:

For prolonged high temperature work, crack resistant (but more expensive). Generally available from more specialist suppliers.

Glass Cups:

The gas cup is made of heat resistant glass (Pyrex or quartz). They can cost more and are not as durable as the other types of gas cups. Therefore they tend to be used when visibility is important, i.e. Welding in awkward spots.

Often, the glass cups are just a piece of straight glass tube and are held in place using o’rings. However, we are now starting to see different sized glass gas cups that have a thread so they can be screwed on (just like the standard gas cups).

Flooding Cups:

As the name suggests, these cups are designed to ensure a good quality weld by improving the shielding gas coverage.

Stubby Cups:

Stubby cups are used in conjunction with a stubby gas nozzle. They reduce the size of the TIG gun so you can access tight spaces. If used in conjunction with a shorter back cap, and shorter tungsten electrode, the TIG torch can fit into even tighter spaces.

Furick Cups:

Furick is a brand name for a cup and its diffuser, collet body (gas nozzle), collet and heatshield (see Furick Fupa, Jazzy, BBW and Mooseknuckle). The cup (along with the gas nozzle) focus the shielding gas, allowing the tungsten electrode to protrude further out from the cup, giving better visibility and more access in tight spaces. They can be purchased as individual parts, or as a kit.

  • Matching the gas flow to the cup you’re using is important in achieving a good quality weld.
  • Ceramic cups often have to match the gas nozzle type, the heat shield and the gun type.
  • Make sure they fit your TIG torch before purchasing.
