340P163069 - ESAB M6 x 28mm CuCrZr Contact Tip for 1.6mm Wire

Reliable ESAB Contact Tip for Heavy-Duty Welding

The ESAB 340P163069 is a premium-quality contact tip designed to keep your MIG welding operations running smoothly and efficiently. As a critical component in the welding circuit, the contact tip is responsible for transferring the welding current to the wire as it passes through the torch. This specific model features a standard M6 thread and a length of 28mm, making it compatible with a wide variety of ESAB and Euro-style MIG guns found in workshops across the country. It is precision-engineered to accommodate 1.6mm (1/16 inch) welding wire, a size commonly used for structural steel fabrication and heavy-plate welding.

What sets this contact tip apart is its material composition. Unlike standard electrolytic copper (E-Cu) tips that can soften and wear out quickly under heat, this tip is manufactured from Copper Chromium Zirconium (CuCrZr). This advanced alloy offers superior hardness and resistance to high temperatures. For the welder, this means fewer interruptions to change out worn tips, less downtime, and a more consistent welding arc over the life of the consumable. Whether you are working on a long production run or a critical repair job, relying on genuine ESAB consumables ensures that your equipment performs as intended.

Proper maintenance of your MIG gun is essential for quality welds, and the contact tip is often the first place to look when issues arise. A worn tip can cause micro-arcing, burnback, and erratic wire feeding. By choosing this high-grade CuCrZr tip, you are investing in better conductivity and mechanical durability. The 1.6mm bore is machined to tight tolerances to ensure smooth wire feeding without excessive play, which helps maintain the aim of the wire into the weld pool. This pack contains one genuine ESAB contact tip, ready to be installed for your next heavy-duty project.

Key Benefits for the User:

• Extended Life: The CuCrZr alloy withstands heat better than standard copper, reducing the frequency of tip changes.


• Precise Fit: The M6 thread ensures a tight, electrically sound connection to the gas diffuser or tip holder.


• Stable Arc: Accurate bore dimensions for 1.6mm wire prevent wandering arcs and improve weld bead consistency.


• Versatility: Suitable for use with various shielding gases and welding modes, including spray transfer and pulsed MIG.
