0558008754 - ESAB 7300µF 250VDC Replacement Capacitor

Restore Optimal Power with the ESAB 7300µF Capacitor

The ESAB 0558008754 Capacitor is a critical internal component designed for specific ESAB welding power sources and plasma cutters. Rated at 7300µF (microfarads) and 250 VDC, this aluminum electrolytic capacitor plays a vital role in the power regulation circuit of your equipment. Capacitors of this magnitude are typically used to smooth out voltage fluctuations after rectification, ensuring that the DC output to the welding arc or cutting stream remains stable and consistent.

Over time, electrolytic capacitors can degrade due to heat, age, and electrical stress. A failing capacitor can lead to symptoms such as unstable arcs, difficulty starting the machine, or even complete power failure. Replacing a worn or bulging capacitor with this genuine ESAB part restores the electrical integrity of your machine, protecting other sensitive components from ripple currents and voltage spikes.

Technical Reliability

Constructed with high-quality aluminum electrolytic materials, this component is engineered to handle the rigorous duty cycles associated with industrial welding. Its 250VDC rating provides ample headroom for standard internal bus voltages found in many inverter and chopper-based power supplies. When performing repairs on industrial equipment, choosing OEM parts like the ESAB 0558008754 ensures that the replacement meets the exact electrical and physical specifications required by the manufacturer.

Installation and Safety

Please note that capacitors store electrical energy even when power is disconnected. It is essential to discharge the capacitor safely before removal or installation. This part should be installed by a qualified technician familiar with welding machine repair and high-voltage safety procedures. Verify your machine's service manual to confirm part number compatibility before ordering.
