771002 - Miller HR100 Replacement MIG Gun Neck Assembly

Get Your HR100 Back in the Fight

There is nothing more frustrating than a MIG gun that just won't feed right. If you've dropped your HR100 or it's taken a beating around the shop, a bent or damaged neck might be the culprit. The Miller 771002 Neck Assembly is the direct replacement you need to fix that HR100 and get back to laying beads. This isn't some cheap knock-off that doesn't thread right; it's the real deal from Miller, designed to fit your gun perfectly.

We know that the neck of the gun takes the most abuse. It gets hot, it gets banged against workpieces, and it gets covered in spatter. Eventually, the internal path for the wire can get kinked or the threads for your tip holder can strip out. When that happens, you don't need to buy a whole new gun. Swapping out the neck with this kit is a quick and cost-effective repair that makes your torch feel brand new again. The angle is factory-correct, meaning your muscle memory for gun positioning won't be thrown off.

Installation is straightforward. The assembly connects securely to your existing handle and cable, ensuring a solid electrical connection and leak-free gas path. Because it's an OEM part, you don't have to worry about filing down fittings or forcing threads. It just works. Whether you are working on automotive body panels, light fabrication, or home projects, keeping your equipment in top shape is key to good results.

Don't let a beat-up torch compromise your welds. If you are seeing erratic feeding or gas coverage issues and you've already checked your liner and tips, check your neck. If it's time for a replacement, the Miller 771002 is the reliable choice to keep your HR100 running smooth. Grab one for your spare parts kit so you are never stuck waiting on shipping when you have a deadline to meet.
