16421140 - Tweco 180-Degree Straight Conductor Tube Replacement

Get the Reach You Need with the Tweco 180-Degree Conductor Tube

Sometimes a standard curved MIG gun neck just doesn't cut it. Whether you are setting up a machine torch or trying to weld down a straight, narrow path where a curved neck would get in the way, the Tweco 1642-1140 Conductor Tube is the solution you need. This is a 180-degree, completely straight "gooseneck" designed to give your Tweco MIG gun a straight-shooter profile. It’s built tough, just like you’d expect from Tweco, ensuring that you can keep laying down beads without worrying about your equipment failing mid-weld.

The conductor tube is the backbone of your MIG gun's front end. It carries the welding current to the tip and directs the shielding gas over the puddle. Over time, these tubes can get battered, bent, or clogged with spatter, leading to poor wire feeding and erratic arcs. Swapping out an old, beat-up neck for a fresh Tweco 1642-1140 restores that smooth wire feed and consistent electrical contact. The copper construction handles the heat, while the heavy-duty insulation keeps you safe from shocks and shorts against the workpiece.

Why choose a straight neck?

• Access: Perfect for reaching through holes or into deep cavities where a bend would hit the sidewalls.
• Automation: Ideal for fixed-mount torches in simple automation setups where the gun points directly down or horizontally at the part.
• Comfort: Some welders prefer a straight grip for specific out-of-position welds or when using a pistol-grip style handle configuration.

Don't let a worn-out torch compromise your weld quality. This genuine Tweco part ensures that your gas diffuser and nozzle fit perfectly, preventing gas turbulence that causes porosity. It’s a quick fix that makes a big difference in how your torch handles and performs. Keep your arc stable and your welds clean with this high-quality replacement tube.
