0559351025 - ESAB 55A Mild Steel Shield Cap for PT-36/PT-37 Plasma Torches

Keep Your ESAB Table Running Smoothly

If you are running an ESAB plasma table with a PT-36 or PT-37 torch, you know that the shield cap is the first line of defense for your consumables. The ESAB 0559351025 is the specific shield cap you need when you are dialed in at 55 Amps on Mild Steel. It sits right at the front of the torch, protecting your nozzle from the molten spray that kicks up when you pierce the plate. A worn-out or clogged shield cap can ruin your gas flow, leading to ugly cuts, bevels you didn't ask for, and nozzles that burn out way too fast.

Why stick with genuine ESAB? Because aftermarket caps often don't have the perfect machining needed for high-def plasma. If the hole isn't perfectly centered, your arc goes sideways, and you waste metal. This cap is built to handle the heat and keep your shield gas flowing exactly where it needs to go—cooling the nozzle and constricting that arc for a laser-like cut on steel.

Don't let a cheap part shut down your production line. Keep a few of these 55A MS caps in your cabinet. When you see the orifice getting out of round or slag building up that you can't scrape off, swap it out. It’s the cheapest insurance you can buy for your expensive torch head and ensures your parts come off the table looking clean and ready for welding.

Application Notes

Make sure you are actually cutting Mild Steel at 55A. If you switch to Stainless or crank the amps up, you need to swap this cap out for the one matching that process. Using this cap at higher amperages will melt it, and using it on stainless might mess up your edge chemistry. Check your consumable map, grab the 0559351025, and get back to cutting.
