0194324001 - ESAB Split Ferrite Core EMI Filter

Genuine ESAB Openable Ferrite Core for Welding Equipment

Maintain the precision and reliability of your welding operations with the ESAB 0194324001 Openable Ferrite Core. In the complex electrical environment of industrial welding, electromagnetic interference (EMI) and radio frequency interference (RFI) can wreak havoc on sensitive control electronics. This genuine ESAB replacement part is designed to suppress these unwanted high-frequency signals, ensuring your equipment operates exactly as intended. Whether you are troubleshooting an error code related to communication faults or simply performing preventative maintenance, replacing a damaged or missing ferrite core is a critical step.

The standout feature of this component is its openable, split-core design. Unlike solid toroidal cores that require cables to be unplugged and threaded through, this unit splits into two halves encased in a durable plastic shell. This allows for immediate installation on existing cables—such as power cords, torch leads, or internal control ribbons—without the need to disconnect wires or shut down complex wiring harnesses. The plastic housing features a robust snap-lock mechanism that holds the ferrite faces tightly together, ensuring maximum magnetic efficiency and noise attenuation.

Using genuine ESAB parts like the 0194324001 ensures that the magnetic properties of the ferrite material match the specific frequency filtering requirements of your ESAB power source. Generic cores may not target the correct noise frequencies generated by inverter switching, leaving your machine vulnerable to interference. This component is commonly found on input power lines to prevent noise from feeding back into the grid, or on internal control lines to protect logic boards from high-power switching noise.

Key Benefits for Maintenance

• Instant Retrofit: Snap-on design requires no tools or rewiring.


• Signal Integrity: Protects sensitive digital controls from electrical noise.


• OEM Quality: Guaranteed fit and performance for ESAB machines.


• Durability: Protective casing prevents chipping of the brittle ferrite material.

At Josef Gas, we understand that small components play a huge role in industrial uptime. This ferrite core is an essential spare part for maintaining the electrical hygiene of your welding fleet.
