ESAB Coolant Level Float Stop Clip

Restore Your Welder's Cooling System with the ESAB 186W46

Keep your rig running cool and efficient with the ESAB 186W46 Stop Float. If you run a water-cooled TIG or MIG setup, you know that the cooling unit is the heart of your thermal management. The coolant level sensor is the watchdog that prevents you from melting down a valuable torch. This stop float is the small but mighty piece that keeps that sensor doing its job correctly. If your machine is throwing weird water errors or if you've noticed the float in your tank looking loose, this is likely the part you need.

Designed specifically for ESAB water circulators, this stop float clips into place to limit the movement of the level float. Without it, the float can wander off, giving your machine false readings. A false "low water" error stops you from welding, killing your productivity. Even worse, a stuck float might tell the machine there is water when there isn't, leading to a dry-running pump or a fried power cable. Swapping out a damaged stop for a fresh 186W46 is a quick, inexpensive fix that saves you from massive headaches down the road.

Don't rely on makeshift fixes or generic clips that might dissolve in your coolant or pop off due to vibration. This is the official ESAB part, meaning it snaps right in where it's supposed to and holds up against the heat and chemistry of welding coolants. It’s a simple repair that any welder or shop tech can handle, getting you back under the hood and laying beads in no time.

Whether you are refurbishing an older ESAB cooler or just fixing a breakdown, using the right parts matters. The 186W46 Stop Float ensures your equipment communicates correctly with the power source, protecting your gear and your wallet. Don't let a ten-dollar plastic part cost you a three-hundred-dollar torch head—replace it with the genuine article.
