W7003202 - Thermal Arc 161 STL and 201 TS Main Control Board PCB

Restore Precision with the W7003202 Control PCB

The ESAB / Thermal Arc W7003202 PCB Control is a critical replacement component designed specifically for the maintenance and repair of the Thermal Arc 161 STL and 201 TS inverter welding machines. As the central nervous system of these advanced DC inverters, the main control board is responsible for regulating output current, managing arc characteristics, and monitoring internal safety systems. When this component fails, the equipment often becomes unusable, leading to costly downtime in industrial and fabrication settings. This genuine OEM part ensures that the machine is returned to its original factory specifications, maintaining the reliability and performance standards expected from Thermal Arc equipment.

Industrial maintenance teams and repair technicians rely on genuine parts to guarantee compatibility and longevity. The W7003202 is manufactured to the exact engineering standards of the original assembly, ensuring that all connectors, mounting points, and thermal clearances align perfectly with the machine's chassis. This eliminates the need for modifications during installation and reduces the risk of subsequent failures. The board comes pre-loaded with the necessary control logic to manage the specific TIG and Stick welding curves of the 161 STL and 201 TS models, ensuring that the arc start, ramp-up, and crater fill functions operate seamlessly immediately after repair.

Investing in a genuine replacement PCB is often the most cost-effective solution compared to replacing an entire welding power source. By swapping out a faulty control board, you extend the service life of your capital equipment. This component is shipped in anti-static packaging to prevent electrostatic discharge (ESD) damage during transit and storage. It is highly recommended that this part be installed by a qualified technician familiar with inverter power supply safety, as proper handling of internal electronics is crucial for both personal safety and the longevity of the new board.
