056823 - Miller 056823 1/16" Threaded Contact Tip, 1.625" Length

Precision Electrical Transfer for Heavy-Duty Welding

The Miller 056823 Contact Tip is a critical consumable component designed for industrial MIG (GMAW) and Flux-Cored (FCAW) welding applications utilizing 1/16-inch (1.6 mm) wire. As the final point of electrical transfer from the welding gun to the filler metal, the contact tip plays a pivotal role in arc stability and overall weld quality. This specific tip features a 1.625-inch length, a standard dimension for compatible Miller MIG guns, ensuring the correct stick-out and relationship with the gas nozzle for optimal shielding gas coverage.

Manufactured from high-grade copper alloy, this tip is engineered to withstand the intense heat and electrical resistance inherent in high-amperage welding. The internal bore is precision-drilled to tight tolerances, minimizing friction while maintaining constant electrical contact with the wire. This reduces the risk of micro-arcing inside the tip, which can lead to premature wear, keyholing, and unstable arc characteristics. The threaded base ensures a secure mechanical and electrical connection to the gas diffuser, facilitating efficient heat dissipation away from the tip end.

In heavy industrial environments where 1/16-inch wire is commonly used for structural steel or heavy fabrication, the durability of the contact tip is paramount. The Miller 056823 is designed to resist erosion caused by the abrasive nature of flux-cored wires and the high heat of spray transfer modes. Regular inspection and replacement of the contact tip are essential for maintaining consistent welding parameters and preventing defects such as porosity or lack of fusion caused by poor electrical transfer.
