Engineered for precision and durability, the AccuLock™ S Contact Tip is designed specifically for 0.045" (1.2mm) wire, making it an essential component for industrial-duty welding applications. Manufactured by Miller Electric in the United States, these tips are compatible with both Miller MDX™-250 and Bernard® BTB MIG Guns, streamlining your consumables inventory while minimizing replacement errors. The innovative coarse thread design allows for quick and easy contact tip replacement, while the alignment and centering feature ensures a flawless wire-feed path, significantly reducing issues such as burnbacks and erratic arcs. Additionally, the tapered locking mechanism enhances electrical conductivity and the cooling of the contact tip tail within the diffuser, ensuring optimal performance during welding tasks.
