264590 - Miller 1.6mm CuCrZr Heavy-Duty Contact Tip (264590)

Maximize Arc Stability with Miller CuCrZr Contact Tips

Upgrade your welding performance with the Miller 264590 Contact Tip, specifically sized for 1.6mm (1/16") wire. For professional welders, the contact tip is the final and most critical point of electrical transfer in the MIG welding circuit. A worn or inferior tip can lead to micro-arcing, burn-backs, and frustrating wire feed issues. This Miller contact tip is crafted from Copper Chromium Zirconium (CuCrZr), a high-performance material chosen for its ability to withstand extreme thermal stress without softening. This makes it the ideal choice for welders pushing high amperages or running long beads where standard copper tips would fail prematurely.

The difference lies in the metallurgy. Standard copper tips can soften and deform as they heat up, leading to "keyholing"—where the exit hole widens and loses contact with the wire. This causes the arc to wander and the voltage to fluctuate. The Miller 264590 resists this deformation, keeping the wire centered and ensuring positive electrical contact throughout the life of the tip. This stability is crucial for achieving X-ray quality welds and maintaining control over the weld puddle, especially in out-of-position welding or when using flux-cored wires that generate significant heat.

Designed as a direct replacement for compatible Miller MIG guns, this single-wire tip is easy to install and provides immediate improvements in process consistency. Whether you are working on heavy fabrication projects, shipyards, or construction sites, using the correct high-quality consumable is the easiest way to improve weld quality. Don't let a cheap tip compromise your work; choose the Miller 264590 for reliable, heavy-duty performance that keeps you welding longer with fewer interruptions.
