OVERVIEW

Keep Your Velocity Torch Running Cool

You know that a smooth weld starts with a well-maintained gun. The Tweco Velocity series is a beast, but even the best torches need fresh parts to keep performing. This Conductor Tube Insulator (Part #1640-1408) is the small but mighty piece that keeps the juice flowing where it should—into the wire—and not arcing out against your nozzle or other parts of the gun. If you've ever experienced erratic arcs or noticed your nozzle getting unusually hot, a cracked or carbon-tracked insulator might be the culprit.

These insulators are built tough to handle the heat of long beads and high-amperage work. They slide right onto the conductor tube, providing that essential barrier that stops shorts dead in their tracks. Because they are genuine Tweco parts, you don't have to fight to get them to fit; they snap into place perfectly, ensuring your shielding gas flows smoothly without turbulence caused by ill-fitting generic parts.

We know these things can get beat up on the shop floor, which is why they come in a pack of 5. Toss a pack in your toolbox or locker so you're never caught waiting on a delivery truck when you should be burning wire. Swapping out a crispy insulator takes seconds but saves you hours of frustration and troubleshooting down the line. Protect your investment and your weld quality with fresh insulators.
