Pro-source 57N74 Tig Torch Nozzle 1/2 Inch Orifice

Product Description

The PRO-SOURCE 57N74 is a TIG torch nozzle designed to direct and shape the shielding gas flow around the tungsten electrode during gas tungsten arc welding (GTAW) operations. With a 1/2 inch orifice opening, this nozzle controls the gas coverage area at the weld puddle, helping maintain a clean, uncontaminated arc zone. It is a consumable replacement component used by welding professionals in fabrication shops, maintenance facilities, and field repair environments. The compact form factor — measuring approximately 1.68 inches in height and 0.97 inches in diameter — fits standard torch body configurations for the torch series listed below.

This nozzle is suited for light to medium TIG welding applications on ferrous and non-ferrous metals where precise shielding gas control is required. It is compatible with torch models 17, 18, and 26, which are widely used air-cooled TIG torch configurations found across general fabrication and maintenance welding setups. Sold individually, it is intended for use in environments where nozzles are replaced routinely as part of standard consumable maintenance.

Key Features

• 1/2 inch orifice opening for defined shielding gas coverage at the weld zone
• Compatible with torch models 17, 18, and 26
• Compact dimensions: 1.68 inches height, 0.97 inches width and length
• Lightweight at 0.056 pounds for minimal torch balance impact
• Sold as an individual replacement unit for flexible consumable stocking

Compatibility

Designed for use with TIG torch models 17, 18, and 26 as stated in the manufacturer product data.

Installation Notes

TIG torch nozzle replacement is performed by welding technicians as part of routine consumable maintenance. Always shut off the shielding gas supply and allow the torch to cool completely before removing or installing a nozzle. Thread or seat the nozzle carefully to avoid cross-threading or cracking the ceramic body. Verify gas flow and arc stability before returning the torch to production use.
