Your MIG gun is only as good as its neck. If you are running a Tweco Spray Master 450 and dealing with erratic wire feeding, overheating, or a bent tube from a drop, it's time to swap it out. The Tweco MS64-60S (1640-1342) is the factory-standard 60-degree conductor tube built to restore your gun to peak performance. Known in the shop as the "gooseneck," this part takes the most abuse—heat, spatter, and the occasional hammer-use (we know you do it)—so replacing it with a genuine Tweco part ensures you keep running smooth beads without interruption.
The 60-degree angle on this tube is the sweet spot for most welding positions. It gives you enough curve to see your puddle clearly while keeping your hand in a comfortable, natural position, whether you are welding flat, horizontal, or overhead. Because it is designed for the 450-amp Spray Master, it is built thick and tough. It handles high heat without getting soft or warping, meaning you spend less time waiting for the gun to cool down and more time burning wire. The copper construction conducts current efficiently, ensuring that the power from your machine actually makes it to the wire.
Installation is a breeze—just loosen the set screw on your handle, pull the old neck, and slide this one in. It fits tight and locks down solid. Don't struggle with a clogged or damaged neck that ruins your liner and frustrates your day. A fresh conductor tube is one of the cheapest ways to make an old gun feel brand new again. This tube accepts all your standard Spray Master consumables, so you don't need to change your tips or nozzles. Grab a spare for the tool crib so you are never down for long.
