Restore Your MiniArc 150 to Peak Performance

The ESAB MiniArc 150 is a legendary compact welder known for its portability and reliable arc characteristics. However, like all sophisticated inverter-based machines, the internal electronics are the heart of the operation. When your machine fails to power up, loses arc stability, or stops outputting current altogether, the culprit is often the main control board. The ESAB Main Inverter PCB (0558003339) is the genuine OEM replacement part designed specifically to get your MiniArc 150 back in the field.

Using genuine ESAB parts is critical when repairing inverter power sources.
