264595 - Miller 1.2mm CuCrZr Contact Tip for Twin Wire Systems

Miller 264595 Twin Wire Contact Tip Overview

The Miller 264595 is a specialized contact tip designed for high-performance twin wire MIG welding applications. Manufactured from Copper Chromium Zirconium (CuCrZr), this contact tip offers superior physical properties compared to standard electrolytic copper (E-Cu) tips. The addition of chromium and zirconium significantly increases the recrystallization temperature and hardness of the alloy, making it ideal for the intense thermal environments found in high-deposition twin wire welding.

In twin wire or tandem welding processes, two wires are fed into a single weld pool, generating substantial heat and electrical current density. Standard copper tips often soften and wear prematurely under these conditions, leading to keyholing, poor arc stability, and frequent downtime for replacement. The CuCrZr composition of the 264595 ensures that the tip maintains its structural integrity and electrical conductivity over longer periods, ensuring consistent current transfer to the 1.2mm wire.

This contact tip is precision-machined to tight tolerances to ensure smooth wire feeding and optimal electrical contact. It is specifically engineered for 1.2mm welding wires, a common size in heavy industrial fabrication and automated welding cells. By maintaining a stable arc and reducing the frequency of tip changes, the Miller 264595 contributes to higher overall equipment effectiveness (OEE) and weld quality in demanding production environments.
