0258000911 - ESAB M10 Heavy Duty Contact Tip 3/32 Inch

Technical Overview of the ESAB M10 Contact Tip

The ESAB 0258000911 is a high-performance contact tip engineered for industrial MIG and Flux-Cored Arc Welding (FCAW) applications requiring large diameter wires. Manufactured to precise tolerances, this tip features a 2.4mm (3/32-inch) bore designed to accommodate heavy welding wires while maintaining optimal electrical contact. The M10 thread specification indicates a robust connection point, suitable for heavy-duty gas diffusers and swan necks found in high-amperage welding guns, such as the ESAB PSF series.

Material composition is critical in contact tip performance. This unit is fabricated from a high-grade copper alloy selected for its balance of hardness and electrical conductivity. Efficient current transfer is paramount when welding with 3/32" wire, as resistance heating at the contact point can lead to premature failure or micro-arcing. The machined surface finish of the bore minimizes friction, ensuring smooth wire feeding even under the mechanical stress of pushing large diameter consumables through the liner and gun assembly.

In automated and manual industrial environments, the reliability of the contact tip directly influences arc stability. The ESAB M10 tip is designed to withstand the thermal cycling inherent in high-duty-cycle welding, resisting keyholing and bore erosion longer than standard grade tips. This component is an essential consumable for fabrication shops utilizing heavy deposition rates.
