0558004065 - ESAB 5-Quart Coolant Reservoir Tank

Keep Your Cool with a Fresh Tank

If you are running a water-cooled TIG torch or a heavy-duty plasma cutter, you know that the cooling system is the lifeline of your equipment. The ESAB 0558004065 Water Tank is the direct replacement you need when your old reservoir starts showing its age. Maybe it has developed a hairline crack from years of vibration, or maybe it's just stained and filled with sludge that you can't quite clean out. Swapping in a fresh 5-quart tank is one of the cheapest insurance policies you can buy for your expensive torch and machine.

This isn't just a plastic bucket; it's an OEM part made to fit your ESAB machine exactly. No trying to jam a generic bottle in there or rerouting hoses because the fittings don't line up. It drops right in, connects up, and holds a full 5 quarts of coolant. That capacity is important—it gives your system enough fluid to absorb the massive heat your arc puts out without boiling over. A full, clean tank means your pump doesn't have to work as hard, and your torch stays cool in your hand, even when you are pushing the amperage limit on a long aluminum job.

Leaky tanks are a nightmare in a shop. Coolant on the floor is a slip hazard, and coolant inside your machine can fry circuit boards faster than you can hit the E-stop. If you find yourself constantly topping off your cooler, check the tank. If it's the culprit, this ESAB replacement is the fix. It is built tough to handle the chemicals in welding coolants and the rough environment of a metalworking shop. It won't get brittle and crack just because it got a little hot or cold.

Maintenance is part of the job, and keeping your cooling system sealed and clean is critical. When you install this new tank, it's a great time to flush your lines and put in fresh coolant. You'll notice the difference in how your equipment runs. Don't risk burning up a $400 torch head because of a cracked plastic tank. Grab this ESAB 5-quart reservoir, swap it out, and get back to welding with confidence knowing your cooling system is tight and ready to work.
