W7003222 - Thermal Arc 201 TS Replacement Control Board W7003222

Get Your 201 TS Back in Action

There is nothing worse than a welder that powers on but refuses to weld, or a machine that acts like it has a mind of its own. If your Thermal Arc 201 TS has stopped responding to your settings, or if the arc has become unstable and unpredictable, the issue might lie in the control board. The W7003222 is the genuine replacement brain for your 201 TS, designed to get your rig back to the smooth, reliable performance you remember from day one.

The control board is the heart of your inverter. It tells the machine exactly how much power to output and how to handle the arc. When this board fails—often due to power surges, accumulated metal dust, or just years of hard work—your welder becomes a heavy paperweight. Swapping in this factory-original board eliminates the guesswork. You don't have to worry about "universal" parts that don't quite fit or software that doesn't quite match. This board is plug-and-play for the 201 TS, meaning it speaks the same language as the rest of your machine's components.

Repairing your own equipment can be a great way to save money and minimize downtime, but remember that welding machines store high voltage even when unplugged. If you are comfortable opening up the case, make sure you follow all safety protocols, including discharging capacitors and wearing anti-static gear to protect the new board. Once installed, this board restores your ability to fine-tune your TIG and Stick settings, giving you back the control you need for precision welds.

Don't let a fried circuit board force you to buy a whole new machine. The Thermal Arc 201 TS is a workhorse worth saving. With the W7003222, you are investing in the continued life of your equipment, ensuring it remains a reliable tool in your arsenal for years to come.
