16501120 - Tweco WeldSkill 500A 60-Degree Conductor Tube Replacement

Restore Your WeldSkill 500 to Peak Performance

If your MIG gun is starting to overheat, feed wire erratically, or if the neck has become bent or damaged from heavy shop use, it is time to swap out the conductor tube. The Tweco 1650-1120 is the genuine replacement neck for your WeldSkill WM500 MIG gun. Designed with a standard 60-degree bend, this tube gets you back to the comfortable welding angle you are used to, helping you lay down smooth beads without fighting the torch.

We know that in a busy shop, equipment takes a beating. The conductor tube is the backbone of your MIG gun's front end. It holds the diffuser and nozzle in place and carries the massive 500 amps of current needed for heavy fabrication. When an old tube gets clogged with liner shavings or damaged internally, it creates resistance that kills your arc stability. This replacement part is built tough with heavy-wall copper to handle the heat and keep the current flowing smoothly to your contact tip.

Installation is straightforward, allowing you to get back under the hood quickly. Simply disconnect the old tube from the handle, transfer your consumables, and lock the new 1650-1120 in place. The 60-degree angle is perfect for general fabrication, structural steel, and heavy equipment repair, offering good visibility of the puddle while keeping your hand at a natural angle. Don't let a worn-out gooseneck compromise your weld quality—keep your WeldSkill gun running like new with this authentic Tweco part.

Whether you are welding mild steel, stainless, or aluminum, having a straight, clean, and conductive path for your wire is non-negotiable. This tube ensures that your wire feeds without drag and your gas coverage remains consistent, reducing cleanup time and rework.
