16401310 - Tweco 64J-80 Flexible Conductor Tube 80 Degree for Mini-MIG

Get Your Mini-MIG Back in Action with the Tweco 64J-80

If your Tweco Mini-MIG gun is starting to stutter, feed wire poorly, or just feels like it's seen better days, the problem might be right in the neck. The Tweco 1640-1310 (Model 64J-80) is the genuine replacement flexible conductor tube you need to get back to laying smooth beads. This isn't just a piece of pipe; it's the backbone of your gun's front end, responsible for delivering the power and the gas exactly where you need it.

Why Choose the Flexible 80-Degree Tube?
Welding isn't always done on a flat bench at waist height. Sometimes you have to get into tight corners, weld around obstacles, or hold the gun at awkward angles. The 80-degree bend on this conductor tube is the classic configuration for the Mini-MIG, offering a comfortable wrist angle that reduces fatigue during long sessions. The "Flex" design adds a layer of durability and versatility, forgiving the bumps and knocks that happen in a real shop environment while allowing you to maneuver the gun more easily than a strictly rigid neck might allow.

Signs You Need a Replacement
Conductor tubes are consumables, even if they last longer than tips and nozzles. If you notice your wire dragging, the neck getting excessively hot, or if the threads for your diffuser are stripped, it's time to swap it out. A bent or clogged tube kills your arc stability. Installing the 1640-1310 is straightforward and brings your gun back to factory specs instantly. It ensures your liner sits correctly and your contact tip gets the full current it needs to melt wire consistently.

Genuine Tweco Quality
Don't risk your weld quality with knock-off parts that might not fit your Mini-MIG handle correctly. This authentic Tweco part ensures a tight seal for your shielding gas, preventing porosity caused by air leaks at the neck connection. Whether you are doing auto body work, light fabrication, or farm repairs, keeping a spare 64J-80 conductor tube in your toolbox ensures that a damaged gun won't shut down your project for the day.
