993991 - ESAB 993991 Pressure Switch SPDT 0-90 PSI 15A

Reliable Pressure Monitoring with the ESAB 993991

The ESAB 993991 Pressure Switch is a critical component designed to ensure the safe and efficient operation of your industrial welding and cutting equipment. As a Single Pole Double Throw (SPDT) switch, it offers versatile wiring configurations, allowing it to function as either a normally open or normally closed circuit depending on your specific system requirements. This flexibility makes it an essential repair part for a variety of ESAB power sources, particularly in plasma cutting systems where air pressure monitoring is vital for torch cooling and arc stability.

Engineered for precision, this switch features an adjustable pressure range of 0 to 90 PSI. This capability allows technicians to set specific thresholds for safety interlocks, ensuring that the machine will not initiate an arc if the input pressure falls below the required minimum. This protects the torch consumables from premature failure and prevents damage to the power source itself. The switch is rated for 15 Amps at 125 Volts, providing a robust electrical capacity that can handle the signaling loads of industrial control boards without issue.

Installation is straightforward thanks to the industry-standard 1/8-inch NPT connection. This thread size is commonly found in pneumatic manifolds and gas lines within welding equipment, ensuring compatibility with existing plumbing. Whether you are troubleshooting a "low pressure" error code or performing preventative maintenance on an aging machine, replacing a faulty pressure switch with this genuine ESAB part restores factory-level reliability to your equipment. Its compact form factor ensures it fits neatly within the tight confines of machine cabinetry.

Using genuine OEM parts like the ESAB 993991 is crucial for maintaining the safety certifications and performance standards of your equipment. Generic switches may not offer the same cycle life or precise actuation points, leading to nuisance tripping or, worse, safety bypasses. Trust in ESAB's engineering to keep your fabrication operations running smoothly with this high-quality pressure monitoring solution.
