0558007469 - ESAB ESP-150 High Voltage Transformer 3500V

Technical Overview: ESAB High Voltage Transformer 0558007469

The ESAB 0558007469 is a specialized High Voltage Transformer (XFMR) engineered exclusively for the ESAB ESP-150 plasma cutting power source. This component is integral to the machine's high-frequency or pilot arc starting circuit, stepping up the input voltage to a potential of 3500V. This high voltage is necessary to ionize the air gap and establish the plasma arc, ensuring consistent ignition and stable cutting performance.

As an Original Equipment Manufacturer (OEM) component, this transformer meets the precise inductance and insulation resistance specifications required by the ESP-150 design. Using non-OEM substitutes in high-voltage plasma circuits can lead to component failure, inconsistent arc starting, or damage to the main power board. This unit features heavy-duty windings and high-dielectric insulation materials designed to withstand the thermal and electrical stresses typical of industrial plasma cutting environments.

The assembly is delivered with specific termination points ("W/ESP-150 TERM") designed to mate directly with the ESP-150's internal wiring harness. This ensures a secure, low-resistance connection that eliminates the need for field modifications during installation. Maintenance personnel troubleshooting "no-arc" or "hard-start" conditions on an ESP-150 should verify the output of the existing HV transformer; if replacement is required, this part restores the factory-specified high-voltage output.
