Restore Your ES 300i to Factory Condition

When your welder goes down, every minute counts. The ESAB 0445092880 PFC Inductor Board Assembly is the direct replacement part you need to get your ESAB ES 300i welding machine back in production. This assembly is a vital part of the machine's power supply architecture, specifically handling Power Factor Correction (PFC). If your machine has stopped powering on, is throwing power-related error codes, or is tripping breakers upon arc initiation, a faulty PFC assembly is a common culprit.

Welders Supply Company provides this authentic ESAB replacement to ensure you aren't gambling with aftermarket electronics. The ES 300i is a high-performance machine known for its versatility and power, and the PFC board is what allows it to run on various input voltages efficiently. This board assembly manages the relationship between voltage and current, ensuring that the energy drawn from the wall is used effectively to create the arc. A damaged inductor board can lead to overheating and reduced duty cycles, severely limiting your productivity.
