GYS Welding Machine Cooling Liquid is a special welding coolant essential to optimise and preserve the performance of your welding machine’s cooling circuit. Its unique anticorrosive and low-conductivity formula reduces electrolysis effects. The liquid prevents the accumulation of sediment and cooling circuit blockage compared to a standard liquid. Ready to use formula requiring no dilution providing frost resistance down to -20°C. GYS recommends that cooling liquid is changed every 2 years.
