When you are pushing high amps on a Deltaweld 350 or 500, heat is your enemy. The Miller Industrial Water Cooler is the dedicated partner your machine needs to keep water-cooled MIG guns operating at peak performance. Whether you are running long beads on heavy structural steel or using an Aluma-Pro™ push-pull gun for aluminum fabrication, this cooler ensures your equipment stays within safe thermal limits up to 600 amps.
Forget about rust contaminating your coolant lines. Miller designed this unit with a durable polyethylene tank and shroud that is impervious to corrosion. This means cleaner coolant, fewer clogs in your torch, and less downtime for maintenance. The industrial-grade rotary vane pump is a standout feature, delivering steady, non-pulsing flow that keeps your torch head cool even during the toughest jobs. It is built with a brass body for longevity and includes a factory-set pressure relief valve (55 PSI) so you never have to worry about blowing out a hose connection.
Setting up is incredibly simple. This cooler is designed to live with your Deltaweld. It plugs right into the 115V outlet on the back of your welder—no electrician required. The low-profile, horizontal design means it tucks neatly under the power source or mounts securely to the Miller Industrial Running Gear. It also features smart touches like internal check valves, which stop coolant from pouring out all over your shop floor when you disconnect your gun for a liner change or repair.
