196515 - Miller Coolmate 3 Replacement Radiator Coil

Keep Your Cool with the Miller 196515 Replacement Radiator

When you are pushing high amperage on a TIG or MIG job, the last thing you need is your water cooler failing. The Miller 196515 Radiator Heat Exchanger is the genuine replacement part you need to get your Miller Coolmate 3, Cool Runner 3X, or Arc Cool V3 system back up and running. Your water cooler works hard to pull heat away from your torch, and the radiator is where that heat gets dumped. If your radiator is clogged with shop dust, bent up from impact, or leaking coolant on the floor, your torch is going to get hot fast. An overheating torch isn't just uncomfortable to hold; it burns up consumables, melts power cables, and can ruin the torch head completely.

This replacement unit is the exact same part that came in your machine from the factory. That means you don't have to worry about trying to rig up a generic cooler core or fighting with hose connections that don't quite fit. It drops right into the chassis of your Coolmate or Cool Runner system. The fins are designed to maximize airflow from the fan, ensuring that your coolant temperature stays low even when you are welding at high amps for extended periods. Keeping your coolant clean and cool is the secret to getting long life out of your water-cooled torches, and a healthy radiator is the key to that equation.

Don't risk your expensive welding equipment with a limping cooling system. If you notice your coolant getting hot or see green puddles under your cart, it's time to swap out the heat exchanger. The Miller 196515 is built tough to handle the vibration and heat of a welding shop. It restores the cooling power you had when the machine was new, giving you the confidence to tackle long welds without stopping to let the torch cool down. Whether you are running a manual TIG setup or a heavy-duty automation cell, this radiator ensures your cooling loop flows freely and dissipates heat efficiently. Get your system fixed right with genuine Miller parts and get back to welding.
