CK gas saver ceramics are designed to simply push on and off for simple and faster nozzle changing.
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).
