Esab 0365310045 Tig Torch Nozzle Size 5 HW20 20A

Product Description

The ESAB 0365310045 is a Size 5 TIG torch nozzle designed to direct and shape the shielding gas flow at the arc zone during tungsten inert gas welding. It features an 8.00 mm (approximately 0.315 inches) orifice opening, which corresponds to the industry-standard Size 5 designation. The nozzle threads or fits onto compatible TIG torch bodies and is a consumable component replaced as part of routine torch maintenance. Welding technicians and fabricators working with GTAW processes install this nozzle when setting up or servicing a torch for precision welds on pipe, sheet metal, or structural work.

This nozzle is rated for use with the HW20 and 20A TIG torch models. It suits applications in light industrial, fabrication shop, and field welding environments where controlled shielding gas coverage is required. A Size 5 nozzle provides a moderate gas coverage diameter, making it a common choice for general-purpose TIG welding on materials such as stainless steel, carbon steel, and aluminum in both shop and maintenance settings.

Installation Notes

TIG torch nozzles are installed and serviced by qualified welders or welding technicians. Before replacing the nozzle, shut off the shielding gas supply and allow the torch to cool completely. Inspect the collet body and back cap for wear before reinstalling a new nozzle. Follow the torch manufacturer's assembly sequence to ensure proper seating and a gas-tight fit.
