0558002345 - ESAB 17 PSI Low Pressure Safety Switch 5A

Protect Your ESAB Equipment with the Right Switch

Is your ESAB plasma cutter or water cooler throwing pressure errors or refusing to arc? The culprit might be a faulty pressure switch. The ESAB 0558002345 Low Pressure Switch is the exact replacement part you need to get your machine back up and running safely. This small but mighty component acts as the guardian of your equipment, constantly monitoring the pressure of your air or coolant lines. When pressure drops below 17 PSI, this switch trips to shut down the system immediately, preventing your torch from burning up and saving you hundreds or thousands of dollars in potential damage.

Why is this switch important?
Plasma cutters and water-cooled welders rely on a steady flow of air or coolant to keep the torch cool and the arc stable. If that flow is interrupted—say, someone steps on a hose or the compressor fails—the internal heat can destroy a torch head in seconds. This 17 PSI switch (rated at 5 Amps) detects that drop instantly and cuts the power. It is a safety net you cannot afford to bypass.

Installation and Compatibility
Designed as a direct replacement for the original part found in many ESAB machines, this switch fits perfectly without the need for modification. It features standard connection points for quick wiring and a threaded port for a secure seal into your machine's plumbing. Whether you are troubleshooting a PowerCut plasma machine or a dedicated cooling unit, swapping out an old, stuck, or leaking switch with this genuine ESAB part restores factory reliability.

Don't risk your gear with generic switches that might not trigger at the right pressure. The 0558002345 is calibrated specifically for ESAB's requirements. Keep a spare on the shelf to minimize downtime, or order today to fix that nagging pressure fault light. It’s a small investment that ensures your heavy-duty industrial equipment keeps humming along shift after shift.
