0559351018 - ESAB 200A Mild Steel Plasma Shield Cup

Keep Your Cuts Clean with Genuine ESAB Parts

If you are running an ESAB plasma table and burning through mild steel plate at 200 amps, the ESAB 0559351018 Shield Cup is the part you need to keep your operation running smoothly. This isn't just a piece of copper and plastic; it's the main line of defense for your expensive torch. When you are piercing thick plate, molten metal and slag are constantly trying to blow back into your nozzle. This shield cup is built tough to deflect that spatter and keep your internal consumables clean and functioning correctly.

We know that in a busy shop, cut quality matters. If your shield cup is beat up, pitted, or the hole is worn out of shape, your arc is going to wander. A wandering arc means beveled edges, dross buildup, and more time spent with a grinder fixing parts that should have come off the table ready to weld. This specific cup is designed for Mild Steel (MS) applications. That means it handles the heat and gas flow exactly right for standard steel cutting, giving you those crisp, vertical edges you want. It fits perfectly on your high-amp torch—likely the PT-36 if you're pushing 200A—and installs in seconds.

Why stick with OEM? Because generic parts often don't line up perfectly. If the shield cup is even a fraction of a millimeter off-center, your nozzle will wear out unevenly, and you'll be burning through tips twice as fast. The ESAB 0559351018 is machined to factory specs, so it centers up every time. It’s also made of high-heat resistant material that doesn't melt or deform under the intense 200-amp load.

Maintenance tip: Check your shield cup at the start of every shift. If you see slag buildup on the face, gently scrape it off. If the center hole looks notched or oval-shaped, toss it and put on a new one. It’s a small cost that saves you big money on nozzles, electrodes, and rework time. Keep a box of these on the shelf so you never have to shut down the machine while waiting for the delivery truck. Get the right part for the job and keep the sparks flying.
