0559210029 - ESAB PSF Series M8 Contact Tip 1.2mm (0.045") CuCrZr

Keep Your Arc Smooth with ESAB PSF Series Tips

If you are running an ESAB PSF 405 or 505 gun, you know that these torches are built for serious heat. But a torch is only as good as the contact tip at the end of it. The ESAB 0559210029 is the M8 contact tip you need when you are pushing 400 amps or burning through heavy plate. This isn't your average soft copper tip that keyholes after a few hours of spray transfer. This is the CuCrZr (Copper-Chrome-Zirconium) version—the heavy-duty option that stands up to the punishment of high-heat welding without fusing to your wire.

We know the frustration of an unstable arc. Usually, it starts with the wire stuttering or the resistance changing because the tip bore has worn out into an oval shape. This tip is designed to resist that wear. It is sized perfectly for 1.2mm (0.045") wire, giving you that crisp, consistent electrical contact you need for smooth bead appearance and deep penetration. The M8 threads are tough and resist stripping, locking tightly into your diffuser so you don't lose gas coverage or conductivity. Whether you are welding mild steel structures, repairing heavy machinery, or fabricating thick sections, this tip helps you keep the hood down and the sparks flying.

This pack gets you the genuine ESAB part, ensuring it fits your PSF gun geometry exactly. No guessing if the stick-out is correct or if the gas nozzle will seat properly. It is designed to work seamlessly with the PSF gas nozzles and diffusers. When you are welding at high parameters, heat buildup is the enemy. The alloy construction of this tip handles that thermal shock better than anything else, meaning you spend less time walking back to the tool crib for parts and more time laying down metal. Make sure you match your drive rolls and liner to the 0.045" size for the best feeding performance.
