0457455008 - ESAB PSF Contact Tip M8 x 37mm for 1.2mm Wire (CuCrZr)

Maximize Arc Stability with ESAB CuCrZr Contact Tips

Every welder knows that the contact tip is the final transfer point for welding current, and its condition directly dictates the quality of the arc. The ESAB 0457455008 Contact Tube is built for professional welders who demand consistency and durability from their equipment. Designed to fit the legendary PSF series MIG guns, this M8 x 37mm tip is sized specifically for 0.045" (1.2mm) wire, a standard diameter for medium-to-heavy fabrication work.

Why Choose CuCrZr?
Standard copper tips can soften and wear out quickly (keyholing) when exposed to the intense heat of spray transfer or high-amperage pulse welding. This ESAB tip is crafted from a Copper Chrome Zirconium alloy. This material is harder and more heat-resistant than standard copper. The result? The tip retains its shape longer, the bore remains round, and the electrical contact remains consistent. This means fewer burnbacks, less troubleshooting, and more time spent laying down beads.

Precision Fit for PSF Guns
If you are running a PSF 305, 405, or 505 torch, this is the high-performance tip you need. The M8 threads are cut cleanly to ensure a tight mechanical and electrical connection to the tip adapter, preventing the resistive heating that kills lesser consumables. The 37mm length is the standard geometry for these guns, ensuring your nozzle stick-out remains correct for optimal gas coverage.

Whether you are welding structural steel, heavy equipment, or pressure vessels, the stability of your wire feed is paramount. A worn tip causes the wire to wander, leading to an erratic arc and potential weld defects. By upgrading to the ESAB 0457455008, you are investing in smoother starts, a more focused arc, and a noticeable improvement in consumable life. Keep your torch running cool and your welds looking hot with genuine ESAB parts.
