Critical Purchase Information

Please Read Before Ordering: Electronic repair parts, including this circuit card, are non-returnable. Once the package is opened or the part is installed, it cannot be sent back. This policy ensures that every customer receives a brand-new, unused electronic component that hasn't been compromised by previous failed installation attempts. We strongly advise having a Certified Miller Technician diagnose your machine to confirm the control board is indeed the point of failure before placing your order.

Installation Advice

While it may be tempting to perform a DIY repair, modern welder electronics are sensitive to static discharge and improper connections. To protect your investment and ensure the longevity of the new board, installation by a qualified professional is required. If you find a defect or problem, it must be diagnosed by a Certified Miller Technician. Have your machine's serial number ready when verifying compatibility to ensure this is the correct part for your generation of the Toolmate 100.
