The 54N5L #5 Long Alumina Nozzle is a specialized TIG welding consumable designed for industrial applications requiring both extended reach and superior gas coverage. Engineered to fit Large Diameter Gas Lens collet bodies (such as the 45V63, 45V64, 995795, and 45V116 series), this nozzle is compatible with industry-standard 17, 18, and 26 series TIG torches, as well as CS300 and CS410 models.
Constructed from high-grade alumina ceramic, this nozzle offers excellent thermal shock resistance and durability under high-amperage conditions. The #5 size provides a 5/16-inch (8.0 mm) orifice, ideal for precision work on thinner materials or tight joints where a focused gas column is necessary. The defining feature of this unit is its extended length (approximately 3 inches), which allows welders to access deep corners, tube clusters, and obstructed joints that standard-length cups cannot reach.
By utilizing a large gas lens setup, this nozzle ensures a laminar gas flow that remains stable even with a longer tungsten stick-out. This combination of a long nozzle and gas lens technology significantly reduces turbulence and oxidation, resulting in cleaner, higher-quality welds on stainless steel, aluminum, and exotic alloys.
