0700156003 - ESAB Replacement Upper Control Board 0700156003

Restore Precision with the ESAB Upper Control PCB

The ESAB Upper Control PCB (Part Number 0700156003) is a critical replacement component designed to restore the functionality of your ESAB welding power source. In modern inverter-based welding machines, the printed circuit boards (PCBs) act as the central nervous system, coordinating everything from arc initiation to complex pulse parameters. The Upper Control PCB typically handles high-level logic, user interface commands, and the regulation of welding output parameters. When this board fails, it can result in erratic arc performance, unresponsive controls, or a complete machine shutdown.

As a genuine OEM part, this circuit board is manufactured to the exact specifications required by your equipment. Substituting with non-OEM electronics in sophisticated welding inverters can lead to calibration drift, communication errors between power modules, or even catastrophic failure of other components. This board undergoes rigorous testing by ESAB to ensure it meets the durability standards expected in industrial environments, where dust, vibration, and electrical noise are common challenges.

Technicians and maintenance professionals understand that diagnosing a faulty PCB is often the final step in troubleshooting a down machine. Once identified, replacing the board with the correct SKU (0700156003) is the fastest route to getting the equipment back online. This unit is shipped in anti-static packaging to protect the sensitive electronic components during transit. Whether you are repairing a Caddy series inverter or another compatible ESAB unit, this board provides the reliability and performance assurance that comes with the ESAB brand.

Installation Note: Printed circuit boards are sensitive to static electricity (ESD). It is highly recommended that installation be performed by a qualified service technician using proper grounding techniques (such as a wrist strap) to prevent damage to the new component during handling.
