0700300336 - ESAB PSF Series M8 Contact Tip 0.035 (0.9mm) - 50 Pack

Technical Specification: ESAB M8 Contact Tip (0700300336)

The ESAB 0700300336 is a high-performance contact tip designed specifically for the ESAB PSF series of MIG welding torches. Engineered with a robust M8 thread, this contact tip offers superior surface area for current transfer compared to standard M6 tips, reducing electrical resistance and minimizing heat buildup at the contact point. The tip features a precise 37mm overall length, which is critical for maintaining the correct stick-out relationship with the gas nozzle in PSF 305, 405, 505, 410W, and 510W gun assemblies.

Manufactured from high-grade Electrolytic Copper (E-Cu), this consumable ensures optimal thermal conductivity and wear resistance. The bore is precision-drilled to accommodate 0.035-inch (0.9mm) solid welding wires, providing a tight tolerance that ensures consistent electrical contact without causing excessive drag on the wire feed system. This balance is essential for maintaining a stable arc and preventing micro-arcing inside the tip, which can lead to premature failure and burn-backs.

This product is supplied in a bulk package of 50 units, intended for high-volume industrial environments where downtime must be minimized. The M8 geometry is particularly suited for medium-to-heavy duty fabrication where welding currents frequently exceed 300 amperes. Proper installation requires ensuring the tip is seated firmly against the gas diffuser to maximize heat dissipation into the torch neck.

Compatibility Note: This tip is designed for the standard PSF front-end geometry. It is not compatible with M6-threaded diffusers or non-ESAB Euro-style torches unless specified.
