38048 - ESAB ESP-100i Isolation Amplifier PCB 38048

Restore Your ESP-100i to Peak Performance

When your trusted ESAB ESP-100i plasma cutter goes down, it stops production cold. If troubleshooting has pointed to a failure in the isolation or amplification circuits, the ESAB 38048 PCB is the exact part you need to get back up and running. This isn't a generic knock-off; it is the genuine Original Equipment Manufacturer (OEM) board, meaning it fits perfectly and works exactly like the one that came with your machine when it was new.

Plasma cutters rely on complex electronics to manage the massive energy required to cut through metal. This specific board, the ISO/AMP (Isolation Amplifier), acts as a bridge and a shield inside your machine. It helps manage the signals that tell the machine how much power to push, ensuring your arc is smooth and consistent. If your machine has been acting up—stuttering arcs, error lights, or just refusing to cut—a fried board could be the culprit. Swapping it out with this authentic ESAB part eliminates the guesswork.

We know that downtime costs money. That's why we supply genuine ESAB parts to ensure a repair that lasts. Don't risk your expensive equipment with salvaged or mismatched electronics. This board is designed to handle the heat, dust, and vibration of a welding shop environment. Get your ESP-100i back to slicing through plate with the reliability you expect from ESAB.
