Bernard developed its Centerfire™ Consumable System with the user's cost considerations in mind. Our contact tips, nozzles and diffusers are easy to use and high performing – they provide better arc starts, less spatter and more consistent welds – and also last up to three times longer than competitive brands. These diffusers are sold individually. The D-1 diffusers are used on 300, 400, & 500 amp Bernard MIG Guns. Centerfire Features • No tools required to replace tip or nozzle • "Drop-In" tip with no threads means quick change after burnback, reducing down time • Large diameter tip base and tapered seat provides better electrical conductivity and heat transfer • Spatter shield within nozzle protects diffuser and gives smoother, less turbulent gas flow • Solid, concentric relationship between tip and nozzle keeps tip centered even after hard use... and abuse • Threaded nozzle holds tip fixed at 1/4" or 1/8" recess, flush, or 1/8" stick out • Compatible with all standard air-cooled Bernard Q-Gun and S-Gun MIG Guns • Complete family of tips and nozzles is available to meet most of your welding needs
