OVERVIEW

Maximize Your Arc Stability with ESAB CuCrZr Tips

As a welder, you know that the contact tip is the final transfer point for your welding current, and it takes a beating. If you are tired of your tips wearing out halfway through a shift, or if you are experiencing burnback and erratic arcs as your tip heats up, the ESAB M6 x 28mm CuCrZr contact tip is the upgrade you need. Designed specifically for 1.2mm (0.045") wire, this tip isn't just standard copper—it's engineered with a Copper-Chrome-Zirconium alloy that stands up to the intense heat of the welding arc far better than generic tips.

Why does the material matter? Standard copper tips get soft when they get hot. As they soften, the wire wears out the hole into an oval shape (keyholing), causing the wire to wander and the arc to sputter. CuCrZr tips are harder and retain their shape even under high-amperage loads. This means you get a consistent, focused arc for longer, allowing you to lay down smooth beads without constantly stopping to swap out consumables. Whether you are welding structural steel, heavy equipment, or running long passes in spray transfer mode, this tip handles the heat.

Installation is seamless with the standard M6 thread, fitting perfectly onto your ESAB PSF series gun or any compatible MIG torch. The 28mm length ensures your tip sits at the correct recess or stick-out relative to your nozzle, maintaining proper gas coverage for defect-free welds. Don't let a cheap piece of copper ruin a critical weld or slow down your production. Switch to ESAB's high-performance CuCrZr tips and experience the difference in longevity and arc quality.

Benefits for the Welder

  • Longer Life: Lasts significantly longer than standard copper tips, saving you trips to the tool crib.
  • Stable Arc: Maintains a tight bore tolerance for consistent electrical contact and smooth wire feeding.
  • Heat Resistant: Won't soften or deform easily during high-heat applications like spray transfer.
  • Less Downtime: Spend more time welding and less time troubleshooting contact tip issues.
  • Perfect Fit: Precision M6 threads for a secure, conductive connection to your diffuser.

FAQ

E-Cu (Electrolytic Copper) is standard copper, while CuCrZr (Copper Chromium Zirconium) is an alloy. CuCrZr is harder and withstands higher temperatures without softening, making it last longer in high-heat or high-wear applications.

This contact tip is designed for use with 1.2mm (0.045 inch) welding wire.

The tip features a standard M6 thread.

The total length of the contact tip is 28mm.

Yes, this M6 x 28mm tip is compatible with many ESAB PSF series torches (e.g., PSF 250, 305, 405) that utilize M6 consumables.

While CuCrZr is compatible with aluminum, aluminum wire expands more when heated. It is often recommended to use tips specifically marked for aluminum (often with an 'A' suffix or slightly larger bore) to prevent jamming, though this tip may work if the clearance is sufficient.

The bore size ensures proper electrical contact with the wire. If it is too tight, the wire jams; if it is too loose, micro-arcing occurs inside the tip, causing wear and unstable arcs.

This SKU represents a single contact tip, though they are often purchased in bulk packs for convenience.
