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 brands.Threaded nozzle keeps contact tip centered for better weld placement and less spatter. Holds tips fixed at 1/4" or 1/8" recess, flush, or 1/8" stick out.Composite insulator extends life and withstands heat abuse.Centerfire Nozzles have a built-in spatter shield that smooths and concentrates gas flow for less weld oxidation and contamination.Centerfire Contact Tips have a tapered base to improve conductivity. Diffuser mates securely with contact tip for better conductivity.Centerfire 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 insulator.Rotate to create new wear surfaces and extend tip lifeNo tools needed to change nozzles and contact tipsBetter arc starts, less spatter, more consistent welds
