Tweco 9-5967 Coolant Temperature Switch Assembly

Protect Your Equipment with the ESAB 9-5967 Temp Switch

If your water cooler is acting up or your torch is running hotter than usual, it might be time to check your safety sensors. The ESAB 9-5967 Temperature Switch Assembly is the genuine replacement part you need to get your cooling system back to 100%. Designed specifically for Tweco and ESAB water coolers, this switch acts as the guardian of your equipment, constantly monitoring the temperature of the coolant flowing through your lines.

Why is this part important?
Water-cooled TIG and MIG torches rely on a steady flow of cool liquid to prevent the internal power cables and consumables from melting. If your cooling unit's temperature switch fails, the system might not realize the water is getting too hot. This can lead to "torch burnout," a costly situation where the power cable inside your hose melts, or the torch head itself warps. Conversely, a faulty switch might prevent your cooler from turning on at all, leaving you unable to weld. Installing a fresh 9-5967 assembly ensures that your cooler knows exactly when to ramp up cooling or shut down to save your gear.

OEM Quality and Fit
When it comes to internal repair parts, using genuine components is always the smartest choice. This ESAB/Tweco assembly is built to the exact specifications of your machine. It comes with the necessary leads and connectors to fit right into the existing harness, making the repair process smoother. You won't have to guess about temperature ratings or splice wires from a generic auto-parts store switch. This is the real deal, meant to keep your industrial welder running shift after shift.

Signs you might need this part:

• Your water cooler displays an error code related to temperature.
• The cooling fan runs continuously even when the fluid is cold.
• The system shuts down unexpectedly during long welds.

Don't risk your expensive torches and downtime. Swap out that questionable switch with the ESAB 9-5967 and weld with confidence, knowing your cooling system is monitoring the heat so you don't have to.
