ESAB OrigoMig Replacement Cooling Radiator 0349311701

Keep Your OrigoMig Running Cool

If you are running a water-cooled ESAB OrigoMig setup, you know that the cooling system is the lifeline of your torch. When the radiator gets clogged with shop dust, damaged by debris, or starts to leak, your welding comes to a grinding halt. The ESAB Radiator (0349311701) is the direct replacement part you need to fix your cooling unit and get back to burning wire. A failing radiator doesn't just mean a hot machine; it means your expensive water-cooled gun gets too hot to hold, and you risk melting down your power cable or blowing out o-rings.

This is not a generic 'fits-all' part; it is the genuine ESAB radiator designed specifically for your machine. That means the mounting holes line up, the hose connections are the right size, and it fits inside the case without any modifications. You don't have to worry about zip-tying a mismatched cooler into place. Swapping out an old, leaky, or bent radiator with this fresh unit restores the cooling power your machine had when it was new.

Signs that you might need this part include coolant puddles under your machine, the water cooler alarm triggering frequently, or the fan blowing hot air but the coolant remaining dangerously hot. In many fab shops, the radiator fins get packed with grinding dust that can't be blown out, killing the airflow. Replacing the core is often the only way to ensure your torch stays cool during long welds at high amperage. Protect your gear and stop waiting for the machine to cool down—install the correct replacement radiator and keep your production line moving.

Whether you are doing heavy structural steel or precision aluminum work, consistent cooling is key to consistent welds. Don't let a $500 torch burn up because of a bad radiator. Trust the OEM part to handle the heat.
