16301101 - Tweco 63-45 Conductor Tube 45 Degree for Spray Master MIG Guns

Restore Your Spray Master's Performance

Is your MIG gun sputtering or overheating? A worn or damaged conductor tube—often called a gooseneck—can be the silent killer of weld quality. The Tweco 1630-1101 (63-45) Conductor Tube is the genuine replacement part you need to get your Tweco Spray Master MS350 or MS450 gun back to peak performance. Over time, the internal surface of a conductor tube can degrade, and the threads can wear out, leading to poor conductivity and erratic arcs. Swapping in a fresh 63-45 tube ensures that your welding current flows smoothly and your shielding gas is delivered exactly where it needs to be.

Built for Comfort and Durability
Welding all day takes a toll on your wrists and arms. This conductor tube features a standard 45-degree bend, which is the industry favorite for general fabrication. It provides a natural hand position that reduces fatigue while still allowing you to reach into corners and tight spaces. The heavy-duty construction is designed to withstand the heat of high-amperage welding, meaning you can run your Spray Master at its full potential without worrying about the neck melting down or failing prematurely. It’s built tough to handle the drops, bangs, and scrapes of a real workshop environment.

Quick and Easy Replacement
Time is money, and you don't want to spend hours fixing your torch. The Tweco 63-45 is designed for a perfect fit on Spray Master 350 and 450 amp guns. It installs quickly and securely, so you can get back under the hood faster. Whether you are fabricating heavy structural steel or running production parts, trusting genuine Tweco parts ensures your equipment remains reliable. Don't let a bad neck compromise your welds—upgrade to a new conductor tube and feel the difference in arc stability and control.
