OVERVIEW

Reliable Coolant Flow Monitoring

The ESAB 636383 Flow Switch is a critical component designed to ensure the safe and efficient operation of liquid-cooled welding systems. Engineered to monitor coolant circulation with precision, this switch acts as a primary safety interlock for high-performance TIG and MIG equipment. By detecting coolant flow, it prevents the power source from initiating an arc if the cooling system is not functioning correctly, thereby protecting expensive torches and cables from catastrophic overheating.

Technical Specifications

This unit is calibrated with an actuation point of 1.0 GPM (Gallons Per Minute), making it suitable for standard industrial water circulators that require a steady flow rate to maintain thermal stability. It features a robust construction capable of withstanding pressures up to 1000 PSI, ensuring durability within pressurized closed-loop systems. The switch utilizes a Normally Open (N/O) contact configuration, which closes the circuit only when sufficient flow is detected, providing a fail-safe operation mode.

OEM Quality and Compatibility

As a genuine ESAB replacement part, the 636383 flow switch guarantees seamless compatibility with specific ESAB water coolers and cooling units. Using authentic OEM parts is essential for maintaining the manufacturer's warranty and ensuring that safety parameters are met without modification. This switch is an ideal solution for maintenance technicians looking to repair or refurbish aging cooling equipment to factory standards.

Installation and Safety

Proper installation of the flow switch is vital for equipment protection. It is typically installed in the coolant return or supply line depending on the specific machine architecture. Its high-pressure rating ensures it can handle the hydraulic spikes often associated with pump start-ups. By replacing a faulty or intermittent switch with this new unit, operators can eliminate nuisance tripping and ensure that their welding processes run without interruption due to false cooling alarms.

FAQ

This switch is calibrated to actuate at 1.0 GPM (Gallons Per Minute).

It is a Normally Open (N/O) switch, meaning the circuit is open when there is no flow and closes when flow reaches 1.0 GPM.

The switch is rated for pressures up to 1000 PSI.

This is an OEM part for specific ESAB coolers. Please check your machine's parts manual or the existing switch part number (636383) to confirm compatibility.

A flow switch prevents your water-cooled torch from operating without coolant, which would cause the torch to overheat and fail almost immediately.

This specific model is factory set to 1.0 GPM. It is generally not user-adjustable to ensure safety compliance.

If the switch fails open, your welder may think there is no water flow and refuse to arc. If it fails closed (rare), it might allow welding without water, risking the torch.

Yes, this is a genuine ESAB replacement part, SKU 636383.
