952230 - ESAB Water Cooler Flow Safety Switch 0.5 GPM

Reliable Coolant Flow Monitoring for Industrial Welding Systems

The ESAB 952230 Flow Switch is an essential safety component designed for high-performance welding water coolers. Engineered to monitor the circulation of coolant within TIG and MIG welding systems, this switch features a precise actuation point of 0.5 Gallons Per Minute (GPM). By ensuring that coolant is flowing at an adequate rate before allowing the power source to deliver full amperage, the switch acts as a critical interlock, safeguarding expensive torches and cables from catastrophic thermal failure.

This unit utilizes a Single Pole Single Throw (SPST) configuration, a standard in industrial control logic for simple on/off state detection. When the flow rate meets or exceeds the 0.5 GPM threshold, the switch changes state (typically closing the circuit), signaling to the welding machine that the cooling system is operational. If a blockage, pump failure, or leak causes the flow to drop below this set point, the switch reverts, cutting the safety signal and preventing the arc from striking or continuing. This immediate response is vital in automated and manual heavy-duty welding environments where equipment uptime and longevity are paramount.

Constructed to withstand the rigors of industrial environments, the ESAB 952230 is built with materials compatible with standard welding coolants, including water and glycol mixtures. Its robust design minimizes false alarms while ensuring consistent performance over thousands of cycles. For maintenance teams and equipment repair specialists, replacing a faulty flow switch with this genuine ESAB part ensures that the cooling system operates within the manufacturer's specified parameters, maintaining the validity of equipment warranties and the safety of the welding operator.

Proper integration of the flow switch into the cooling loop is straightforward, typically installed on the return line to verify that coolant has successfully passed through the torch head. Whether used in a standalone water cooler or an integrated cooling unit within a power source, the ESAB 952230 provides the peace of mind required for continuous, high-amperage welding operations.
