Parweld Ultracool coolant is a highly elaborated cooling liquid and it is formulated with multi-metal corrosion inhibitors for safe use in all types of circuits. Its thermal stability and dielectric properties make the cooling liquid especially suitable for MIG/MAG welding torches. Parweld Ultracool coolant can be used to prevent corrosion and blockage of the water lines to effectively prolong the life of the torch and water cooler.
