0487261880 - ESAB Buddy Arc 151i Control Board PCB 0487261880

Genuine ESAB Replacement Control Board

The ESAB 0487261880 PCB Control 151I / A31 is the authentic Original Equipment Manufacturer (OEM) replacement circuit board for the ESAB Buddy Arc 151i inverter welder. For professional repair technicians and equipment owners, using genuine parts is the only way to guarantee a successful repair that returns the machine to its factory operating condition. This specific PCB handles the primary control logic for the A31 series interface, governing the delicate balance of voltage and amperage required for high-quality Stick (SMAW) and TIG (GTAW) welding.

Inverter welders rely heavily on sophisticated electronics to achieve their compact size and superior arc characteristics. The control board is central to this technology, constantly monitoring feedback from the welding arc and adjusting the power module's output in milliseconds. If your Buddy Arc 151i has stopped responding to control inputs, displays error codes, or fails to initiate an arc despite having input power, a faulty control PCB is a likely culprit. Replacing it with this genuine ESAB unit ensures that all safety features, such as thermal overload protection and anti-stick functionality, remain fully operational.

This replacement board (SKU: 0487261880) is manufactured to the same high standards as the original component installed in your machine on the assembly line. It features robust soldering, conformal coating where necessary to protect against conductive dust, and precise connectors for a secure fit. Using OEM parts eliminates the guesswork often associated with repairs; there is no need for modification or recalibration when installing the correct board for the specific model. It is designed to plug directly into the existing architecture of the Buddy Arc 151i.

Welders Supply provides this essential repair part to help you minimize downtime. We recommend that all internal repairs on inverter power sources be performed by qualified personnel, as capacitors can retain dangerous charges even after the machine is unplugged. Ensure your repair is safe and effective with the ESAB PCB Control 151I / A31, and get your welding operations back on track with confidence in your equipment's reliability.
