Large gas lens alumina oxide gas nozzles are the most popular TIG cups, they are made from high-temperature shock-resistant alumina oxide that is injection moulded and when fired they turn pink in colour. 90% of all welding applications use alumina cups.
Large gas lens ceramic nozzles provide a given amount of shielding gas coverage to the weld pool, according to their size, a smaller nozzle provides less gas coverage than a larger one.
Ceramic nozzle orifice sizes are normally denoted by a number which relates to 1/16” (1.6mm) increments, for example a No 6 nozzle would relate to 6 x 1/16” = 3/8” (9.6mm).
These parts fit direct to the Tigama 230 torches and are also compatible with WP9, 20, 17 and 26 type torches.
47081 Size 6 is equivalent to a 57N75.
47082 Size 8 is equivalent to a 57N74.
47115 Size 10 is equivalent to a 53N88.
