Lincoln Electric KP4756-6 Tig Torch Nozzle Size 6 Alumina

Product Description

The LINCOLN ELECTRIC KP4756-6 is a size 6 alumina TIG torch nozzle designed to direct and shape the shielding gas flow around the tungsten electrode during TIG welding operations. Constructed from alumina ceramic, the nozzle provides high-temperature resistance and electrical insulation at the weld zone. It features a standard overall diameter with a 10.0 mm orifice opening, making it suited for general-purpose TIG welding on a range of base metals. This nozzle meets the 10N48 standard and is sold as a single replacement unit, making it a straightforward consumable swap for welding technicians and maintenance professionals.

This nozzle is intended for use with PTA-17, PTA-26, and PTW-18 TIG torch bodies, covering a common range of air-cooled and water-cooled torches found in fabrication shops, maintenance facilities, and industrial production environments. The size 6 designation corresponds to a standard gas cup sizing convention used across TIG consumables. It is appropriate for both light fabrication and general-purpose welding tasks where consistent shielding gas coverage and electrode protection are required.

Compatibility

Designed for use with the PTA-17, PTA-26, and PTW-18 TIG torch bodies. Meets the 10N48 consumable standard.

Installation Notes

TIG torch nozzles are typically replaced by welding technicians during routine consumable maintenance. Before swapping the nozzle, shut down the welder and disconnect the torch from the power source to eliminate shock and arc hazards. Thread or press the nozzle onto the torch body by hand until seated snugly, following the torch manufacturer's assembly guidance. Inspect the collet, collet body, and back cap for wear at the same service interval to ensure full shielding gas integrity.
