Includes one Pyrex cup mounted on a collet body with a 2.4mm measurement diameter with a slit style collet (also in 2.4mm diameter), a heatshield and 2 O-rings.
This kit is designed for 17 and 18 size TIG torches and can also fit onto size 26, but welders may have to run without the use of an insulator due to the complexities of different measurements. The Ally No.5 brand of Pyrex cups is of AC/DC polarity and has an amperage rating of 200.
