0153501010 - ESAB PSF M8 Contact Tip 2.4mm (3/32 inch) CuCrZr - 10 Pack

High-Performance Current Transfer for Heavy Fabrication

The ESAB 0153501010 Contact Tip is a premium consumable designed to meet the rigorous demands of industrial welding environments. Engineered specifically for the ESAB PSF series of MIG torches—including the air-cooled PSF 405 and 505, as well as water-cooled variants like the PSF 410W and 510W—this contact tip represents the critical interface between your power source and the welding arc. This specific model features a robust M8 thread and is bored to accommodate 2.4mm (3/32") welding wire, a diameter typically reserved for high-deposition structural steel fabrication, hardfacing, and heavy equipment manufacturing.

Material composition is the defining characteristic of this component. Unlike standard E-Cu (electrolytic copper) tips which soften rapidly under the extreme heat of high-amperage welding, this tip is manufactured from CuCrZr (Copper Chrome Zirconium). This precipitation-hardened alloy offers a superior balance of electrical conductivity and mechanical hardness. The addition of chromium and zirconium significantly raises the recrystallization temperature of the copper matrix, preventing the tip from annealing and softening during prolonged welds. This resistance to thermal deformation is crucial when running large diameter wires at high duty cycles, as it maintains the structural integrity of the bore and ensures consistent current transfer.

Precision machining ensures that the concentricity of the bore relative to the outer diameter and thread is maintained within tight tolerances. This geometric accuracy is vital for arc stability; a centered wire ensures the arc is directed exactly where the operator intends, reducing weld defects and rework. Furthermore, the smooth internal finish of the bore minimizes friction, allowing for smoother wire feeding and reducing the likelihood of bird-nesting or erratic feeding issues. For maintenance and repair operations (MRO) and heavy manufacturing sectors requiring reliable, high-output welding, the ESAB 0153501010 provides the durability and precision necessary to maintain peak productivity.
