Low-Conductivity Premixed Antifreeze/Coolant - 4L | MIL043810

Keep your welding water-cooling systems protected and operating at peak performance with Miller Low-Conductivity Coolant (Part 043810) — a premium, ready-to-use coolant specifically formulated for TIG, MIG, plasma, and other high-frequency welding applications. Engineered with a 50/50 blend of deionized water and ethylene glycol, this low-conductivity antifreeze helps prevent freezing, boiling, corrosion, scale, and biological growth in closed-loop cooling systems. Perfect for Miller Coolmate™ coolers and compatible systems, it ensures reliable thermal management so you can focus on your welds with confidence.

• Low-Conductivity Formula – Minimizes electrical conductivity in cooling systems, protecting sensitive high-frequency components from shorts or interference.
• All-Weather Protection – 50/50 mix of deionized water and ethylene glycol offers freeze protection down to -37 °F (-38 °C) and boil resistance up to 227 °F (108 °C), extending equipment life in extreme conditions.
• Corrosion & Scale Inhibition – Contains additives that help reduce corrosion, scale buildup, and biological growth inside cooling loops, reducing maintenance frequency.
• Ready-to-Use – Pre-mixed and supplied in a convenient 1 gallon bottle — no dilution or mixing required, saving time and avoiding errors.
• Wide Welding Application Compatibility – Ideal for Miller Coolmate™ systems and other water-cooled welders for TIG, MIG, plasma, resistance, and induction setups (not for systems with aluminum coolant circuits).
• Durable Performance – Helps maintain consistent cooling efficiency and protects internal pump and radiator components for longer service life.
