0469692002 - ESAB Water Pump for OCF-2 and Origo Mig 4000iW/5000iW

Keep Your Torch Cool and Your Arc Hot

If your water-cooled ESAB rig is throwing cooling alarms or your torch handle is getting too hot to hold, it might be time to check your water pump. The ESAB Replacement Pump (0469692002) is the direct factory replacement for the pump found in OCF-2 cooling units and the Origo Mig 4000iW and 5000iW welding machines. When you are pushing high amps all day, your cooling system is the only thing standing between a productive shift and a melted gun.

Water pumps are the heart of your cooling system, circulating fluid from the reservoir up to the torch head and back. When they start to fail, you might notice a strange noise, a leak, or just the dreaded error code on your machine's panel. Ignoring these signs can lead to catastrophic failure of your MIG gun or TIG torch, costing you hundreds in replacement parts. Swapping out a tired pump with this fresh OEM unit brings your flow rate back to spec, ensuring your consumables last longer and your equipment stays safe.

This isn't a generic 'one-size-fits-all' motor; it's the specific pump ESAB designed for your machine. That means the mounting points line up, the plumbing connections fit, and the electrical leads are ready to go. You won't have to fight with it to get it installed. It is built to handle the demands of a shop environment, moving coolant reliably shift after shift.

Don't let a $5 part failure ruin a $500 torch. If your OCF-2 or MIG 4000/5000iW is struggling to keep cool, this replacement pump is the fix you need. Get your machine back up and running with the confidence that comes from using genuine ESAB parts.
