11601802 - Tweco M8 CuCrZr Contact Tip 1/16 (1.6mm) x 30mm

High-Performance CuCrZr Contact Tip for Industrial MIG Welding

The Tweco 1160-1802 is a premium-grade contact tip designed to meet the rigorous demands of heavy industrial and robotic welding applications. Engineered with a specific M8 thread and a 30mm length, this tip is precision-machined to accommodate 1/16-inch (1.6mm) welding wires. The defining characteristic of this component is its material composition: Copper-Chromium-Zirconium (CuCrZr). Unlike standard E-Cu (electrolytic copper) tips, CuCrZr alloys are precipitation-hardened, providing exceptional resistance to mechanical wear and thermal deformation.

In high-amperage welding environments, contact tips are subjected to extreme heat which can soften standard copper, leading to rapid bore expansion ('keyholing') and erratic arc transfer. The CuCrZr alloy maintains its hardness at elevated temperatures, ensuring consistent electrical contact and wire guidance over a much longer service life. This stability is critical for maintaining weld quality in automated systems where downtime for consumable changes directly impacts throughput.

This contact tip features a precise bore tolerance optimized for 1.6mm wire, ensuring smooth feeding while maintaining the necessary electrical contact for stable arc initiation. The M8 thread ensures a secure, high-conductivity connection to the gas diffuser or tip holder. It is an essential component for fabricators seeking to optimize their welding process efficiency and reduce consumable waste.
