KP4159-1 - Lincoln Electric Low Conductivity Coolant for Cool Arc 47 - 1 Gallon

Technical Overview of Lincoln Electric KP4159-1

The Lincoln Electric KP4159-1 is a premium Low Conductivity Coolant specifically engineered for the demands of industrial welding environments. Designed primarily for the Cool Arc® 47 Water Cooling System, this fluid is an integral component in maintaining the thermal stability and operational integrity of high-performance water-cooled MIG and TIG equipment. The formulation is distinct from standard industrial coolants due to its strictly controlled low conductivity properties, which are critical when the cooling fluid circulates around electrically charged components within the welding torch.

Using improper fluids, such as tap water or automotive antifreeze, can introduce conductive ions into the cooling system. In a welding context, this conductivity can lead to electrolysis, causing rapid corrosion of the copper and brass components within the torch head and the cooling unit itself. The KP4159-1 formulation mitigates this risk by ensuring a high dielectric strength, effectively insulating the cooling path from the welding current. This protection extends the lifespan of the power cable, the torch head, and the pump assembly within the cooler.

In addition to its electrical properties, this coolant provides robust protection against environmental factors. It includes inhibitors that prevent the growth of algae and bacteria, which can otherwise form sludge and block the narrow cooling passages of modern welding torches. The fluid also offers freeze protection, ensuring that equipment stored in unheated workshops or transport vehicles remains safe from bursting lines or cracked reservoirs during freezing temperatures. The coolant comes in a 1-gallon plastic bottle and is ready to use without dilution.
