0558003340 - ESAB MiniArc 150 Main Control Board Replacement

Get Your MiniArc 150 Back in Action

Is your ESAB MiniArc 150 acting up or refusing to strike an arc? It might be time to replace the main brain of the operation. The ESAB 0558003340 PCB Control Board is the factory-original replacement part you need to fix a fried or malfunctioning welder. Inverter welders like the MiniArc rely heavily on their electronics to smooth out the power and give you that buttery arc you love. If the board goes bad due to a power spike, dust buildup, or just old age, your welder becomes a heavy paperweight. This part is the fix.

Don't risk your machine with salvaged or 'universal' parts that never quite work right. This is the exact board ESAB put in the machine when it was built. It fits right into the existing mounts and plugs into your existing harness, making the swap straightforward for those comfortable with machine repair. Once installed, you'll get back the crisp arc starts and steady amperage control you had when the machine was new.

Symptoms of a bad board can range from the machine turning on but not welding, to weird noises, or the amperage knob doing absolutely nothing. If you've checked your connections and power supply and narrowed it down to the internals, this control board is often the culprit. Swap it out, close up the case, and get back to burning rod without the frustration of a glitchy machine.
