0467118001 - ESAB Replacement Water Flow Sensor Switch

Keep Your Cool and Keep Welding

If your water cooler isn't registering flow, you risk frying your torch in the middle of a job. The ESAB Waterflow Switch (0467118001) is the replacement part you need to get your cooling unit back online and your torch protected. We all know that water-cooled torches are expensive, and running them without water—even for a few seconds at high amps—can turn your internal power cable into a fuse.

This switch is the watchdog of your cooling system. It sits in the water line and tells your welder, "Yes, we have water, you are clear to weld." If that flow stops for any reason—like a kinked hose or a dying pump—this switch trips and stops the arc, saving your gear. If your machine is throwing flow errors or refusing to arc up despite the pump running, a faulty flow switch is a common culprit.

Swapping this out is a straightforward repair that restores the safety features of your rig. Don't bypass safety switches or guess with generic parts; this genuine ESAB unit is built to fit right and work right. It’s cheap insurance for your expensive TIG or MIG guns. Get your cooler fixed properly so you can focus on the puddle, not the temperature of your handle.

Why You Need This:

• Torch Safety: Stops the welder instantly if water stops flowing.
• Direct Fit: Made for ESAB coolers, so it fits without modification.
• Peace of Mind: Weld heavy amps without worrying about melting your leads.
