043007 - Miller Coolmate 3 Water Cooler System 115V, 3 Gallon

Keep Your Torch Cool and Your Welds Consistent

When you are pushing high amperage on a TIG or MIG job, the last thing you need is an overheated torch forcing you to stop. The Miller Coolmate 3 is the welder's choice for reliable, continuous cooling. This 3-gallon powerhouse is built to handle water-cooled torches rated up to 600 amps, making it perfect for heavy fabrication, aluminum TIG welding, and high-production manufacturing. Its horizontal, stackable design means it fits perfectly under your power source or on your running gear, keeping your setup clean and organized without taking up extra floor space.

Miller has packed the Coolmate 3 with features that make your life easier. The front panel features a "paddle wheel" flow indicator—a simple but essential tool that lets you verify coolant flow at a glance before you strike an arc. No more guessing if the pump is running. Speaking of the pump, this unit uses a heavy-duty brass rotary vane pump rather than a cheaper plastic alternative, ensuring consistent pressure and long-term durability. The tank itself is molded from polyethylene, so you never have to worry about rust contaminating your coolant lines.

Setup is plug-and-play with standard 5/8-18 left-hand fittings that work with almost all major water-cooled TIG and MIG torches. The included 10-foot power cord gives you the reach you need to plug into a wall outlet or the auxiliary power on your welder. Whether you are running a Dynasty, a Syncrowave, or a heavy-duty MIG setup, the Coolmate 3 provides the thermal protection your equipment needs to run at 100% duty cycle. Protect your consumables, prevent cable failure, and weld longer with the industry standard in water cooling systems.
