57016100 - Arcair Protex Welding Coolant - 1 Gallon Case (Pack of 4)

Premium Protection for Liquid-Cooled Welding Systems

The Arcair Protex Coolant (SKU: 57-016-100) is a high-performance heat transfer fluid specifically engineered for the rigorous demands of industrial welding and cutting environments. Supplied here as a convenient pack of four 1-gallon (3.8L) bottles, this coolant is an essential consumable for maintaining the operational integrity of liquid-cooled MIG guns, TIG torches, and plasma arc cutting systems. Unlike standard water, which can cause mineral buildup, corrosion, and freezing, Protex is a scientifically formulated solution designed to maximize equipment lifespan and performance.

One of the critical features of Arcair Protex is its dielectric nature. In high-amperage welding and high-frequency starting applications, it is vital that the cooling fluid does not conduct electricity. Conductive fluids can lead to arc tracking inside the torch head, damaging the torch and potentially shocking the operator. Protex maintains high dielectric strength to prevent these issues. Additionally, the fluid is formulated to provide freeze protection down to -30°F (-34°C), making it suitable for workshops in colder climates or equipment stored in unheated environments overnight.

Beyond thermal management, Protex acts as a lubricant for the internal components of your water cooler. It conditions pump seals, vanes, and O-rings, reducing friction and wear over time. This lubrication helps prevent the common failure of coolant pumps seizing after periods of inactivity. The solution also contains inhibitors to prevent galvanic corrosion and algae growth, ensuring that flow passages remain clear and heat transfer efficiency remains high throughout the fluid's service life.

This product is ready to use and does not require dilution, ensuring the correct mixture ratio for optimal protection every time. It is compatible with most major brands of welding water coolers and recirculators.
