W7005602 - Fabricator 211i Replacement Display PCB Assembly

Technical Overview of the W7005602 PCB Display

The W7005602 is a specialized Printed Circuit Board (PCB) assembly designed exclusively for the interface management of the Fabricator 211i multi-process welding system. Manufactured under the ESAB/Tweco/Thermal Arc umbrella, this component serves as the primary visual output driver for the machine's front panel. It interprets logic signals from the main control board and converts them into alphanumeric visual data, allowing operators to monitor critical welding parameters such as voltage, amperage, and inductance settings.

As an OEM component, the W7005602 adheres to strict manufacturing tolerances regarding circuit path resistance, component placement, and thermal stability. The board features integrated display modules—typically 7-segment LED or LCD based—that are calibrated to match the refresh rates and logic levels of the Fabricator 211i's processor. Failure of this component often results in a "blind" machine where the welding output may still function, but the operator loses the ability to fine-tune settings or view error codes. Replacing the display PCB restores the Human-Machine Interface (HMI) to factory specifications.

Technicians installing this part should observe standard ESD (Electrostatic Discharge) precautions. The board connects via ribbon cables or multi-pin headers directly to the main inverter control assembly. Verification of the specific machine model (Fabricator 211i) is essential, as firmware revisions and board layouts differ significantly between the 181i, 211i, and 252i series. This SKU represents the specific revision required for the 211i chassis.
