0154381001 - ESAB PSF Contact Tip M8 1.0mm (0.040")

Technical Specifications of ESAB 0154381001

The ESAB 0154381001 is a standard contact tube designed for the PSF series of MIG welding torches. It features an M8 thread specification, which provides a robust mechanical connection and efficient current transfer from the diffuser to the welding wire. The total length of the component is 37mm, adhering to the standard geometry required for PSF gas nozzles to ensure optimal shielding gas coverage.

This specific contact tube is bored for 1.0mm (0.040-inch) welding wire. The internal tolerance is strictly controlled to minimize friction while maintaining sufficient electrical contact. It is manufactured from a high-grade copper alloy, selected for its balance of hardness and electrical conductivity, ensuring resistance to erosion caused by the moving wire and heat generated during the welding process.

Compatibility extends across the medium to heavy-duty range of ESAB's PSF line, including the PSF 250, PSF 305, PSF 405, and PSF 505 air-cooled and water-cooled guns. Proper installation requires tightening to the manufacturer's specified torque to prevent overheating at the thread interface.
