Cool Arc 40 Radiator Replacement Kit

Keep Your Cool Arc 40 Running Strong

Don't let a leaking or inefficient water cooler stop your production. The Lincoln Electric Heat Exchanger Kit is the solution for repairing the Cool Arc 40 water cooler found on many Precision TIG welding stations. Water coolers are the unsung heroes of the welding shop, allowing TIG welders to operate at high amperages for extended periods without burning up torches. When the radiator (heat exchanger) in your cooler fails, it can lead to messy coolant puddles on the shop floor and, worse, overheated equipment.

This replacement kit is designed to get your Lincoln Cool Arc 40 back in action quickly. It is a genuine Lincoln Electric part, meaning it is built to the same rigorous standards as the original machine. The heat exchanger is responsible for taking the hot coolant returning from the torch and cooling it down before it circulates back. If your current unit is leaking from the core or has bent/clogged fins that restrict airflow, this replacement will restore the cooling power your TIG torch needs.

Direct Replacement for Precision TIG Coolers

The Cool Arc 40 is the standard undermount cooler for the legendary Precision TIG series (225, 275, 375). This heat exchanger kit is specifically tailored for this unit, ensuring a hassle-free installation. There is no need to modify brackets or force connections; it drops right in. Keeping your cooler in top condition is cheaper than replacing a water-cooled torch head or power cable assembly. If you notice your coolant temperature rising or see signs of leakage around the cooler vents, it is time to swap out the heat exchanger.

Protect Your Equipment

Welding with an overheating cooling system is a recipe for disaster. It stresses the pump and can cause expensive damage to the torch. By installing this new heat exchanger, you ensure efficient heat rejection, keeping your coolant at the optimal temperature. This translates to longer consumable life, better arc stability, and a cooler handle for the welder. Trust genuine Lincoln parts to keep your shop productive and safe.
