COOL1 - Bernard COOL1 Low Conductivity Welding Coolant - 1 Gallon

Keep Your Torch Cool and Your System Safe

Don't let overheating or freezing ruin your expensive water-cooled gear. Bernard COOL1 is the industry-standard coolant for keeping your TIG and MIG setups running at peak performance. Whether you are pushing high amps on aluminum or running long duty cycles in a fabrication shop, your water cooler is the heart of your thermal management system. Using the right fluid is just as important as using the right wire or tungsten.

Why not just use water or car antifreeze? Regular water can grow algae that clogs your lines, and tap water contains minerals that build up scale inside your torch head, eventually killing it. Automotive antifreeze often contains conductive additives that can mess with your TIG high-frequency start and damage pump seals. Bernard COOL1 is formulated specifically for welders. It stops algae, lubricates your pump to keep it quiet and efficient, and won't conduct electricity where it shouldn't.

This 1-gallon jug comes ready to pour—no measuring or mixing required. It protects your equipment from freezing temperatures down to -37°F, so you don't have to worry about cracked lines or busted pumps if the shop gets cold overnight. Switch to COOL1 to ensure consistent coolant flow, cooler torch handles, and longer consumable life.
