The Miller Industrial Water Cooler (301759) is a heavy-duty cooling solution engineered specifically for the Deltaweld® 350 and Deltaweld® 500 MIG welding systems. Designed to support high-amperage applications, this cooler is rated for use with water-cooled MIG guns and push-pull Aluma-Pro™ guns operating up to 600 amps. By maintaining optimal operating temperatures, it extends the lifespan of your consumables and torches while ensuring consistent weld quality during extended duty cycles.
Built for the harsh industrial environment, the unit features a polyethylene-molded coolant tank, fan shroud, and filler spout. This material choice makes the system completely rustproof, preventing the corrosion and particulate buildup that often plagues metal tanks. At the heart of the system is a brass-body, positive-displacement rotary vane pump. Unlike standard impeller pumps, this rotary vane design provides consistent coolant flow and pressure, ensuring reliable cooling performance even as the filter ages. The pump is factory-set with a pressure-relief valve at 55 PSI, protecting your torch lines from over-pressure damage.
Integration is effortless with the Deltaweld series. The cooler operates on 115-volt input power and is designed to plug directly into the dedicated 115V receptacle found on the Deltaweld power source, eliminating the need for extra wall drops or extension cords. Its horizontal form factor allows for convenient stacking or mounting directly onto the Miller® Industrial Running Gear (#301758). For added safety and maintenance ease, the unit is equipped with internal check valves that prevent coolant backflow and spillage when the torch is disconnected. The motor is also thermally protected, automatically shutting down if it overheats to prevent catastrophic failure.
The cooler utilizes an efficient fin-and-tube heat exchanger to rapidly dissipate heat from the coolant. With a 2.5-gallon capacity, it holds enough thermal mass to handle demanding industrial schedules without rapid temperature spikes. Weighing in at 125 pounds (56.7 kg) dry, it is a substantial piece of equipment designed to stay put and perform reliably shift after shift.
