K2187-1 - Lincoln Cool Arc 40 230V Welding Water Cooler

Reliable Torch Cooling at an Affordable Price

Keep your welding equipment running smoothly and protect your investment with the Lincoln Electric Cool Arc® 40 Water Cooler. Whether you are running a high-output TIG setup or a heavy-duty MIG station, heat is the enemy of your torch and consumables. The Cool Arc 40 (230V model) offers a cost-effective and highly reliable solution to manage that heat, ensuring your torch stays cool in your hand and your consumables last longer. This unit is perfect for fabrication shops, automotive repair centers, and serious hobbyists who demand professional-grade performance without the extreme price tag of complex industrial chillers.

What sets the Cool Arc 40 apart is its smart design focused on durability and ease of use. It features a genuine Pro-Con® water pump, a brand trusted by welders for decades for its longevity and smooth operation. Unlike some coolers that vibrate excessively, the Cool Arc 40 runs smoothly, minimizing vibrations that could otherwise transfer to your torch and affect your weld precision. The cooling fan is a muffin-style tube axial design, which means it moves a lot of air to cool the water in the 2-gallon reservoir but does so quietly. You won't have to shout over the noise of your cooler, making your shop a more pleasant place to work.

Setup is a breeze thanks to the color-coded connections on the front panel. You simply connect your blue hose to the blue port and your red hose to the red port—no guessing required. The unit is also incredibly versatile; you can stand it up vertically or lay it flat horizontally depending on the space available on your welding cart or bench. It works seamlessly with all Lincoln water-cooled systems, including Cobramatic torches, and is compatible with standard TIG and MIG torches from other brands that use standard fittings. While it can run on tap water, we recommend using a proper welding coolant to protect against freezing and corrosion, ensuring your Cool Arc 40 lasts for years to come.
