Clean Air SeriesDura-Flux Fixed Liner SeriesFILTAIR Fume Extraction Series Legacy Q-Gun and S-Gun SeriesWire " to 1/8" ( to mm) Centerfire Series Consumables are easy-to-use and high performing. Developed with the user's cost consideration in mind, Centerfire Series Consumables provide better arc starts, less spatter and more consistent welds, while lasting up to three times longer than most nozzle keeps contact tip centered for better weld placement and less spatter.

2 Holds tips fixed at 1/4" or 1/8" recess, flush, or 1/8" stick insulator extends life and withstands heat Nozzles have a built-in spatter shield that smooths and concentrates gas glow for less weld oxidation and Contact Tips have a tapered base to improve conductivity. Diffuser mates securely with contact tip for better HD Consumables are designed for shipbuilding, trailer fabrication and other heavy manufacturing operations. These heavy-duty nozzles feature an easily removable and replaceable nozzle cone (the most frequently damaged part of the nozzle), thicker walls and a new, high temperature to create new wear surfaces and extend tip lifeNo tools needed to change nozzles and contact tipsBetter arc starts, less spatter, more consistent welds2 Centerfire SeriesSmall Centerfire Gas Diffusers and NozzlesNozzlesNS-5800C 5/8" Bore, Flush, .875" , CopperNS-5818C 5/8" Bore, 1/8" Recess, .875" , CopperNS-5800B 5/8" Bore, Flush.
