0458679881 - ESAB PSF M8 Contact Tip 1.0mm (0.040") CuCrZr

Keep Your Arc Smooth and Steady

Every welder knows that the contact tip is the unsung hero of the MIG gun. It’s the final transfer point for all that welding current, and if it’s worn out or cheap, your welds will show it. The ESAB 0458679881 is the genuine replacement tip for your PSF series gun (like the PSF 305, 405, or 505), designed to keep you welding smoothly without the constant frustration of burnbacks or erratic arcs. This isn't just a piece of copper; it's a heavy-duty M8 tip made from a Copper Chrome Zirconium (CuCrZr) alloy. That means it stands up to heat way better than standard E-Cu tips, lasting longer so you spend more time under the hood and less time swapping out parts.

If you are running 0.040" (1.0mm) wire, this is the tip you need. The bore is machined perfectly to let the wire slide through without dragging, but tight enough to ensure solid electrical contact. That solid contact is crucial for a stable arc. When a tip gets sloppy, the wire rattles around, the arc wanders, and you get spatter everywhere. This ESAB tip keeps the wire centered and the current flowing directly where it needs to go. Plus, the M8 threads are beefy—they screw in tight and transfer heat away from the tip faster, keeping everything cooler during those long beads.

Whether you are fabricating heavy structural steel or doing precision work with your Aristo machine, using the right consumables makes the job easier. Don't settle for generic knock-offs that melt halfway through the shift. Stick with the ESAB 0458679881 to get the performance your machine was built to deliver. It’s a small part that makes a massive difference in your daily grind. Check your gun model, grab a handful of these tips, and keep your beads looking professional.
