340P123262 - ESAB M8x30mm CuCrZr Contact Tip for 1.2mm Wire

High-Performance ESAB Contact Tip for Industrial Applications

The ESAB 340P123262 Contact Tip is a premium consumable designed to meet the rigorous demands of modern industrial welding environments. Engineered with a specific M8 thread and a 30mm length, this tip is compatible with a broad range of ESAB MIG guns, particularly those in the PSF series and other Euro-connector style torches. The critical differentiator of this component is its material composition: Copper Chromium Zirconium (CuCrZr). Unlike standard electrolytic copper (E-Cu) tips, CuCrZr alloys offer superior hardness and a much higher softening temperature (approx. 500°C vs 250°C for E-Cu). This metallurgical advantage ensures the tip maintains its structural integrity and bore geometry even under the intense thermal cycling of high-amperage or pulsed MIG welding.

Precision machining is at the core of ESAB's manufacturing process. The bore is drilled to exact tolerances to accommodate 1.2mm (0.045") welding wire, ensuring consistent electrical contact—the 'sliding contact' essential for a stable arc. A worn or ovalized bore can lead to micro-arcing inside the tip, causing wire burn-back and unstable transfer modes. By utilizing CuCrZr, this contact tip resists the mechanical wear of the feeding wire and the erosion caused by electrical transfer, significantly extending the service life of the consumable. This translates to reduced downtime for tip changes and higher overall equipment effectiveness (OEE) in automated or continuous manual welding operations.

For fabrication shops dealing with structural steel, heavy machinery, or automotive components, the reliability of the contact tip is paramount. The ESAB M8x30mm CuCrZr tip provides the thermal conductivity required to dissipate heat effectively while resisting the adhesion of spatter better than softer copper alternatives. It is an essential component for maintaining weld quality and process efficiency in demanding MIG/MAG applications.
