0468500004 - ESAB PSF M6 Contact Tip 0.8mm/0.9mm (Pack of 10)

Precision Engineered ESAB PSF Contact Tips

The ESAB 0468500004 PSF M6 Contact Tip is a critical consumable designed specifically for the widely respected ESAB PSF series of MIG welding torches. As the final transfer point of welding current to the wire, the quality of your contact tip directly influences arc stability, wire feed smoothness, and overall weld quality. ESAB has engineered these tips with a specific metallurgy and bore tolerance to handle the rigorous demands of industrial fabrication.

One of the standout features of this specific tip is its dual-application rating. It is marked and engineered to accommodate 0.9mm (0.035") wire when using 100% CO2 shielding gas, and 0.8mm (0.030") wire when using Mixed Gas (Argon/CO2). This distinction is crucial because different shielding gases affect the thermal expansion of the contact tip and the arc characteristics. By optimizing the bore size to account for these thermal variances, ESAB ensures that the wire maintains consistent electrical contact without binding or floating excessively in the tube. This attention to detail helps prevent micro-arcing inside the tip, which is a common cause of premature failure and burn-back.

Constructed from a high-durability copper alloy, these M6 threaded tips provide excellent thermal conductivity, effectively drawing heat away from the wire interface to the gun neck. This thermal management is essential for maintaining the structural integrity of the tip during long weld cycles. The tips are compatible with a broad range of PSF torches, including the PSF 250, PSF 305, PSF 405, and PSF 505, making them a versatile addition to any shop using ESAB equipment. Supplied in a pack of 10, these tips ensure you have the necessary inventory to keep production moving without interruption.
