0559351056 - ESAB 200A Oxygen Plasma Nozzle for Mild Steel

Get Clean Cuts with the ESAB 200A Oxygen Tip

If you are running a high-production plasma table, you know that cut quality and uptime are everything. The ESAB 0559351056 is your go-to replacement tip when you are burning mild steel plate at 200 Amps using Oxygen. This isn't just a piece of copper; it's the business end of your machine. When you are pushing 200 amps, you need a nozzle that can handle the heat and keep the arc focused tight. This OEM tip is built to do exactly that, giving you straight edges, minimal dross, and the speed you expect from your equipment.

Why does the "O2 MS" marking matter? Because cutting mild steel with oxygen is the fastest way to get the job done. The oxygen reacts with the steel to create extra heat, helping the plasma jet blow through thick plate like butter. But that reaction is hot—really hot. This tip is designed to withstand that thermal shock without melting down or deforming, provided your coolant flow is good. The "MRKD-STD" means the part number and specs are clearly marked, so you don't have to guess if you grabbed the right part out of the bin. There is nothing worse than blowing a consumable because you accidentally installed a 100A tip for a 200A job.

Changing out your consumables regularly is key to keeping your table running smooth. If you see your cut edges starting to bevel or if the dross is getting hard to chip off, check your tip. If the hole in the center isn't perfectly round anymore, it's time to swap it out for a fresh 0559351056. Using genuine ESAB parts means you aren't fighting with fitment issues or inconsistent machining. You get the same performance every time you open a new box.

This tip is designed for the heavy hitters. Whether you are cutting parts for heavy equipment, structural steel, or tank fabrication, this 200A nozzle gives you the power to cut thick sections efficiently. Make sure to pair it with the correct electrode and shield cap for your specific torch setup to get the maximum life out of the consumable. Keep a stock on hand so you never have to shut down the line waiting for parts.
