Miller 500 A Conical Nozzle
This Miller Enterprises copper nozzle is rated for 500 A duty and features a 5/8 in bore with a conical profile. It threads directly onto compatible MIG guns and accepts FasTip contact tips. The part is sold new and the insulator must be purchased separately.
Check Gun Series and Tip Compatibility
Verify that your gun belongs to the FasTip, Spoolmatic 15, Spoolmatic 30, XR-Aluma-Pro or XR-Pistol series before ordering. Confirm the contact tips in use are FasTip type so they seat correctly inside this nozzle. The insulator is not included and must match the gun model.
Fits Threaded FasTip Guns — Insulator Sold
The threaded connection secures the nozzle to supported Miller guns including models 130831, 195156, 198127 through 198130, 300001, 300003, 300004 and 301568 through 301573. Copper construction handles heavy-duty cycles while the separate insulator protects the gas diffuser. Buyers needing a slip-on nozzle or an integrated insulator should select a different part.
