16401305 - Tweco WeldSkill 400 MIG Gun Conductor Tube 60 Degree

Get Your WeldSkill 400 Back in Action

When your MIG gun takes a beating, the conductor tube (or gooseneck) is often the first part to suffer. Whether it's been dropped, bent out of shape, or simply worn out from thousands of hours of arc time, a damaged neck can ruin your wire feeding and make welding a nightmare. The Tweco 1640-1305 Conductor Tube is the direct replacement you need for your WeldSkill 400 (WM400) MIG gun. It gets your equipment back to factory specs so you can get back to laying beads.

This isn't a generic knock-off; it's a genuine Tweco part designed to handle the heat of 400-amp welding. The 60-degree bend gives you the classic angle you're used to, allowing you to access joints comfortably without straining your wrist. The heavy-duty construction ensures that the current flows smoothly to the tip, giving you that crisp, consistent arc start you expect from a Tweco gun.

Why Replace Your Conductor Tube?

A worn-out conductor tube causes more headaches than most welders realize. If the internal bore is grooved or clogged, your wire will drag, causing erratic feeding and burn-backs. If the threads are stripped, your diffuser won't seat right, leading to gas coverage issues and porosity. Swapping in a fresh 1640-1305 tube is a quick, affordable fix that can solve multiple performance issues instantly.

• Perfect Fit: Screws directly into your WeldSkill 400 handle—no modifications needed.
• Built Tough: Rugged metal jacket resists spatter and shop abuse.
• Optimal Angle: The 60-degree J-bend is the standard for general fabrication work.
• High Conductivity: Copper construction keeps the heat at the weld, not in your hand.

Don't let a beat-up torch slow down your production. Keep a spare Tweco 1640-1305 in your tool crib or on your truck. It’s the professional's choice for maintaining the reliability and performance of the WeldSkill 400 series MIG guns.
