11601708 - Tweco EL16RZT-52 Eliminator Contact Tip .052 Zirconium (25-Pack)

Tweco 1160-1708 EL16RZT-52 Contact Tip Specifications

The Tweco 1160-1708 (Part Number: EL16RZT-52) is a premium contact tip designed for the Tweco Eliminator series of MIG guns. Engineered for precision and longevity, this tip accommodates 0.052-inch (1.3 mm) welding wire. It is manufactured from a high-grade Zirconium Copper alloy, which offers distinct metallurgical advantages over standard E-Cu (Electrolytic Tough Pitch Copper) tips. The addition of zirconium significantly increases the softening temperature of the copper, allowing the tip to maintain structural integrity and bore concentricity even during prolonged high-amperage welding cycles.

Technical Performance and Geometry

The "RZT" designation in the part number indicates specific geometric properties. The tip is designed to sit in a recessed position relative to the nozzle exit. This recess is critical for certain welding procedures, as it allows for a longer electrode stick-out (ESO) when necessary and helps shield the tip face from direct radiant heat and spatter accumulation. The tapered profile ensures optimal gas flow dynamics within the nozzle, reducing turbulence and ensuring robust shielding of the weld pool.

Compatibility and Installation

These contact tips feature the signature Eliminator series mechanical connection. They utilize a robust thread form that provides a secure electrical and thermal interface with the gas diffuser. This design maximizes current transfer efficiency, which is vital for maintaining a stable arc characteristic in spray transfer or pulsed MIG modes. The tips are compatible with standard Eliminator gas diffusers and nozzles, making them a drop-in replacement for any setup currently utilizing the EL16 series platform.

Industrial Applications

Supplied in a quantity of 25, these tips are ideal for high-volume fabrication environments. The 0.052" size is frequently utilized in heavy manufacturing, shipbuilding, and structural steel erection where deposition rates are critical. The enhanced wear resistance of the zirconium alloy makes these tips particularly suitable for automated or semi-automated processes where minimizing downtime for maintenance is a priority. By resisting bore wear (ovalization), the EL16RZT-52 ensures consistent wire targeting and electrical contact throughout its service life.
