How to Make a Welding Torch Stay Cool

Use a TIG torch with a water cooling mechanism when at all possible. Water cycles through the torch when in use to prevent overheating. TIG stands for "tungsten inert gas," which helps provide the electrode used in the welding process.

Hook up the water hose from a TIG welding torch to a welding water cooler's "water out" connection. The hose is designed for welding torches that have a specialized connection that attaches to the torch and the cooler.

Connect your power cable from the torch to the power supply. There is a connecter in the middle of the power cable designed for returning the warm water to the cooler from the torch. Attach that connection back to the water input on the cooler using a red return hose.

Plug the cooler into the 110-volt plug in your torch's power supply.

Adjust the pump on your cooler to 50 psi. Many pumps come set at 60 psi, which is usually too high for your torch. Check your manual on how to adjust the pump pressure or call the manufacturer because it varies per model.

Fill the cooler with distilled water. Regular tap water may have minerals in it that damage your torch over time.

Add pre-mixed coolant into the cooler in accordance with your cooler's instructions. Only use coolant designed for welding water coolers. Automotive coolant damages your torch. Once everything is hooked up properly, your torch should run safely without overheating.
