OVERVIEW

Reliable System Monitoring with the Miller 239359 Pressure Switch

The Miller 239359 Pressure Switch is a critical component designed to maintain the operational integrity of your industrial welding equipment. Engineered specifically for hydraulic and coolant applications, this switch serves as a vital safety and monitoring device, ensuring that your systems maintain the necessary pressure for optimal performance. With a calibrated actuation point of 100 PSI, it provides precise feedback to your machine's control systems, helping to prevent damage caused by over-pressure or under-pressure conditions depending on the circuit design.

This switch features a Single Pole Single Throw (SPST) configuration and operates as Normally Open (NO). This means the circuit remains open until the pressure threshold is reached, at which point the switch closes to complete the circuit. This logic is commonly used in safety interlocks and status indicators for water coolers and hydraulic power sources found in heavy-duty welding setups. Using genuine Miller OEM parts like the 239359 ensures that the electrical specifications and physical fittings match your equipment perfectly, eliminating the risks associated with generic aftermarket replacements.

Durability is key in industrial environments. The Miller 239359 is built to withstand the rigors of daily use, including exposure to industrial fluids and the vibration typical of welding workshops. Whether you are maintaining a fleet of TIG coolers or servicing hydraulic fabrication machinery, this pressure switch offers the reliability professional technicians demand. Trust in Miller's engineering to keep your production lines running smoothly and your expensive equipment protected.

FAQ

The Miller 239359 pressure switch is rated for 100 PSI.

SPST stands for Single Pole Single Throw, and NO stands for Normally Open. This means the switch has one input and one output, and the circuit is open (disconnected) until the pressure reaches 100 PSI, at which point it closes.

Yes, this is a genuine Miller OEM part with the internal SKU MIL239359.

The product is labeled for 'HYD' (Hydraulic) applications, making it suitable for hydraulic fluids and standard welding coolants.

No, this is a Normally Open (NO) switch. Replacing a NC switch with a NO switch will cause the system to operate incorrectly or trigger error codes.

Symptoms often include coolant flow error codes on your welder, the cooler pump not engaging, or the machine failing to detect that the cooler is on.

OEM repair parts typically do not come with detailed instructions. It is recommended to consult the service manual for your specific Miller machine.

It is primarily used to monitor pressure in welding water coolers and hydraulic systems associated with Miller industrial equipment.
