W7004969 - Tweco Fabricator 141i/181i Remote Interface Control Board

Restore Your Welder's Remote Control Features

Is your Tweco or Thermal Arc Fabricator welder ignoring your foot pedal? If you are stepping on the gas but the amperage isn't changing, or if your remote hand control seems dead, the culprit is often the remote interface board. The W7004969 PCB is the direct replacement part you need to get your Fabricator 141i or 181i back in the game. This isn't just a generic circuit board; it's the brain that listens to your remote accessories and tells the welder exactly how much power to output.

Welding machines are workhorses, but internal electronics can fail due to power surges, dust accumulation, or simple age. When the remote interface board goes bad, you lose the precision control that makes TIG welding effective. Instead of buying a completely new machine, swapping out the faulty board is a cost-effective repair that extends the life of your equipment. This genuine ESAB/Tweco part is designed to fit perfectly inside your machine's case, plugging directly into the existing wiring harness without the need for soldering or modification.

Why choose this OEM part?

• Guaranteed Fit: No guessing games. It fits the mounting points and plugs of the 141i and 181i perfectly.
• Safety: Welding machines deal with high currents. Using genuine parts ensures the internal logic handles that power safely.
• Performance: Get back that smooth, responsive pedal action you had when the machine was new.

Don't let a fried circuit board stop your fabrication projects. With the W7004969, you can perform the repair and get back to laying perfect beads. Please note: We always recommend unplugging the machine and allowing capacitors to discharge before opening the case to replace internal electronics.
