0700300376 - ESAB PSF M8 Contact Tip 1.2mm CuCrZr Heavy Duty

Keep Your Arc Stable and Your Downtime Low

As a welder, you know that the contact tip is the unsung hero of the MIG gun. It is the final transfer point for welding current, and when it fails, your arc starts to wander, sputter, and ruin your rhythm. The ESAB M8x30mm CuCrZr HD Contact Tip is built to solve the frustrations of cheap, soft copper tips that wear out halfway through a shift. Made from a tough Copper-Chrome-Zirconium alloy, this tip is designed to take the heat—literally.

If you are running 1.2mm (0.045") wire, this tip is the perfect match. The "HD" stands for Heavy Duty, meaning it resists the "keyholing" effect where the wire wears an oval shape into the tip exit. When a tip keyholes, you lose positive electrical contact, leading to an erratic arc and frustrating burn-backs. The harder alloy of this ESAB tip maintains its round bore shape much longer than standard copper, giving you a smooth, hissing arc for hours on end. This means fewer trips to the tool crib and more time dropping dimes.

The M8 thread ensures a solid, high-conductivity connection to your gas diffuser or tip holder, preventing the resistive heating that can melt threads and seize parts together. At 30mm long, it sits perfectly in standard nozzles to ensure your gas coverage is exactly where it needs to be. Whether you are pushing high amps on thick plate or running long beads on structural steel, this tip handles the thermal stress without softening.

Don't let a worn-out tip compromise your weld quality. By upgrading to ESAB's CuCrZr tips, you aren't just buying a consumable; you are investing in consistency. You get better starts, fewer wire feed issues, and the confidence that your equipment can keep up with your skills. It is a small upgrade that makes a massive difference in your daily welding experience.
