Bossweld alumina Cup Size 4

Bossweld Alumina Cup Size 4, 6.0mm, 9/20 Series fits 9 and 20 series TIG torches. It is supplied in a pack of 2.

The alumina cup (also called a nozzle) is the ceramic cup at the front of the torch. It directs the shielding gas over the weld pool and insulates the torch head, and its size sets the gas coverage: a larger cup covers a wider area, while a smaller cup gets into tighter joints.

Key specifications

Choosing the right option

Pick the cup series to match your torch (17/18/26 or 9/20), then the size to suit the joint: a larger cup gives wider gas coverage, and a smaller cup gives access in tight corners. Alumina is a ceramic, so replace a cup that is cracked or chipped.
