0558038286 - ESAB MobileMaster IV & AVS Suitcase Feeder Control Board

Restore Your Feeder's Reliability

Is your ESAB MobileMaster IV or AVS suitcase feeder acting up? Erratic wire feeding, stuttering motors, or a complete loss of control can often be traced back to a failing main control board. The ESAB 0558038286 PCB Control Suitcase AVS/MMIV is the genuine replacement part you need to get your equipment back in the fight. Don't let a faulty circuit board stop your production or force you to buy a brand-new feeder.

Why Choose Genuine ESAB Parts?
Portable wire feeders take a beating. They get dragged across decks, hung from scaffolding, and exposed to dust and moisture. This OEM control board is built to the exact specifications of your original machine, ensuring it fits perfectly and works immediately. It handles the complex job of reading the welding arc voltage and adjusting the wire speed on the fly, giving you that smooth, buttery feed you expect from ESAB equipment.

Installation and Performance
Swapping out a control board is a straightforward repair for most maintenance personnel. Once installed, this board restores the precise control over wire speed that is critical for passing x-ray quality welds. Whether you are running Flux-Cored wire on a bridge or MIG welding in a fab shop, this board ensures your parameters stay where you set them.

Symptoms of a Bad Board:

• Wire speed fluctuates without moving the dial.
• Feeder runs at full speed only.
• Feeder does not respond to the gun trigger.
• Arc voltage sensing features stop working.
