16461706 - Tweco QTRW64180L Water-Cooled Robotic MIG Gun Neck

Keep Your Robot Running Cool and True

Every welder knows that the neck of the gun takes the most abuse, especially in a robotic cell where the arc never seems to stop. The Tweco QTRW64180L Conductor Tube is the heavy-duty replacement neck you need when your automation equipment requires maintenance. Identified by internal SKU TWE1646-1706, this water-cooled gooseneck is built to handle the heat of high-amperage MIG welding without flinching. If your current tube is clogged, bent from a crash, or leaking coolant, this genuine Tweco part is the exact fit to get your system back online.

Why is the water-cooled design so important? In robotic welding, duty cycles often approach 100%. Without efficient cooling, a standard conductor tube would overheat, causing the copper to soften and the consumables to fuse. The QTRW64180L features internal cooling channels that keep the neck rigid and the front-end parts cool. This means fewer contact tip burn-backs, less spatter adhesion, and a much longer life for your nozzle and diffuser. It’s designed to withstand the mechanical stresses of rapid robot movements and the thermal shock of starting and stopping high-energy arcs.

Swapping out a conductor tube on a robot isn't just about bolting on a new part; it's about geometry. This tube is manufactured with strict adherence to the QTRW series specifications, ensuring that the angle and length match your robot's existing setup perfectly. This consistency helps maintain your Tool Center Point (TCP), so you don't have to waste hours touching up points on the teach pendant. Rugged, reliable, and ready for work, the Tweco QTRW64180L is the professional choice for maintaining peak performance in your robotic welding cell.
