197728 - Miller 197728 XR Series MIG Gun Nozzle, 5/8 in Orifice, 2-Pack

Keep Your XR Gun Running Smoothly

When you are deep into an aluminum welding project, the last thing you need is equipment trouble slowing you down. The Miller 197728 Nozzle is the genuine replacement part you need for your Miller XR-Aluma-Pro or XR-W MIG gun. Designed to fit perfectly with your push-pull system, these nozzles ensure that your shielding gas is delivered exactly where it needs to be—covering the puddle and keeping porosity at bay. Aluminum welding is unforgiving when it comes to gas coverage, and using a fresh, undamaged nozzle is one of the easiest ways to ensure your welds pass inspection every time.

This 2-pack of standard nozzles features a 5/8-inch orifice, which is the go-to size for most general fabrication tasks. It gives you a great balance of gas coverage and visibility of the arc. The 2-1/2 inch length is standard for these guns, setting your contact tip at the right depth to prevent burn-backs while keeping it close enough for a stable arc. Because they are made by Miller, you don't have to worry about struggling to thread them on or having them rattle loose in the middle of a bead. They fit tight and stay put.

Over time, every nozzle gets beat up. Spatter builds up, the edges get dinged from cleaning, or they just wear out from the heat. A worn-out nozzle can disrupt your gas flow, leading to erratic arcs and bad welds. By keeping a pack of these 197728 nozzles in your toolbox, you can swap out a bad nozzle in seconds and get right back to burning wire. The copper construction is tough enough to handle the heat of high-amperage welding, and they clean up relatively easily if you keep up with your anti-spatter spray or dip.

Don't compromise your Miller equipment with generic parts that might not fit quite right. These nozzles are built to the exact specs of your XR gun, ensuring that your gas diffuser and contact tip work in harmony. Whether you are building trailers, boats, or signage, reliable consumables are the backbone of a productive day. Grab a pack of Miller 197728 nozzles and keep your arc smooth and your welds clean.
