W7005336 - Cigweld Transmig 250i Main Control PCB Assembly

Genuine Cigweld Control PCB for 250A Inverter Welders

The Cigweld W7005336 PCB Control 250A is a critical replacement component designed to restore the functionality of your high-performance welding equipment. As the central "brain" of your inverter welding machine, this printed circuit board manages the complex interplay of electrical currents, voltage regulation, and user inputs that define modern welding performance. When your machine's control board fails, it can lead to erratic arc behavior, failure to initiate an arc, or a complete system shutdown. Installing this genuine OEM part ensures that your equipment operates exactly as the manufacturer intended, maintaining the safety and efficiency standards of the Cigweld brand.

This specific board is engineered for 250-amp class machines, commonly found in the Transmig inverter series. It handles the logic for various welding processes, including MIG, TIG, and Stick functions depending on the machine's capabilities. The board features high-quality surface-mount components and robust traces designed to withstand the thermal cycling and vibration inherent in industrial environments. Furthermore, the PCB is treated with a protective conformal coating, which helps shield sensitive electronic components from conductive dust, moisture, and metal filings that are omnipresent in welding workshops.

Replacing a main control board is a cost-effective alternative to replacing an entire power source. By choosing the W7005336, you are investing in the longevity of your asset. Unlike aftermarket or salvaged boards, this factory-new unit comes with the assurance of correct firmware and calibration settings required for your specific 250A model. It integrates seamlessly with the machine's existing wiring harness, utilizing standard Molex-style or ribbon connectors for a secure electrical connection. Whether you are troubleshooting a "dead" machine or resolving intermittent control issues, this PCB is the definitive solution for professional repair.

Note: Installation of internal electronic components in welding power sources involves exposure to high voltage capacitors and mains power. It is strongly recommended that this part be installed by a qualified service technician to ensure safety and proper calibration.
