0004676360 - ESAB ATHC4 Replacement Main Control Board

Restore Precision to Your Plasma Automation

The ESAB ATHC4-MB Main Board (Part Number: 0004676360) is a critical replacement component designed specifically for the ESAB ATHC4 Arc Voltage Torch Height Control system. In the world of automated plasma cutting, the reliability of the height control unit is paramount. The ATHC4 system is responsible for monitoring the arc voltage and adjusting the torch-to-plate distance in real-time, ensuring that the cut quality remains consistent regardless of plate warpage or thermal distortion. When the main board fails, the entire automation process can be compromised, leading to poor cuts, crashed torches, or complete system downtime.

This genuine OEM circuit board is engineered to the exact specifications of the original equipment. It serves as the central processing unit for the height controller, interpreting signals from the plasma power source and sending commands to the Z-axis motor drive. By using the authentic ESAB ATHC4-MB, you ensure that signal integrity is maintained and that the logic governing the height sensitivity and response speed operates exactly as the manufacturer intended. The board is built with industrial-grade components to resist the electrical noise and environmental factors common in heavy fabrication shops.

Installation of the 0004676360 main board should be performed by a qualified technician familiar with ESAB automation equipment. Once installed, it restores the full functionality of the ATHC4, allowing operators to resume high-precision cutting. This board handles the complex algorithms required to distinguish between actual arc voltage fluctuations and noise, providing the smooth, responsive torch motion that ESAB systems are known for. Whether you are repairing a breakdown or stocking critical spares for a high-volume production line, this main board is the definitive solution for ATHC4 maintenance.
