300419 - Miller Coolmate 3.5 Runner Package with Dual Cylinder Rack

Industrial Cooling & Mobility Solution

The Miller Coolmate 3.5 with Cart and Dual Cylinder Rack (SKU: 300419) is a comprehensive cooling and transport solution designed for professional industrial welding environments. This package centers around the robust Coolmate 3.5, a 3.5-gallon water coolant system engineered to maintain optimal operating temperatures for water-cooled TIG and MIG torches. By preventing overheating, this system extends the lifespan of your consumables and torches, ensuring consistent weld quality during high-amperage applications.

The unit features a polyethylene-molded tank and shroud, making it impervious to rust and highly resistant to impact—ideal for harsh shop conditions. The industrial vane pump is designed for longevity, delivering steady pressure and flow. What sets this specific configuration apart is the inclusion of the integrated running gear and dual cylinder rack. This setup transforms your stationary welding station into a fully mobile unit, capable of carrying the power source, the cooler, and two full-size gas cylinders. This is particularly advantageous for fabricators who switch between processes (e.g., TIG and MIG) and require different shielding gases on hand.

Installation is straightforward, with the cooler designed to stack neatly under compatible Miller power sources like the Dynasty or Maxstar series. The 115V input allows it to run off standard wall power or the auxiliary power receptacle found on many industrial welders. The filter assembly is easily accessible, simplifying routine maintenance and ensuring the coolant lines remain free of particulate buildup.
