100A PWM Amazon.com just wondered if this pwm has automatic brake for wire feed motor, to stop wire stick out on my old blushed motor century welder. Or is this control or motor brake only manual, it seems hard to tell by the description. Any body know about this pwm. THANKS.

It is forward reverse and brake. It is an h-bridge using mosfets. the question would be how the switch is wired. The center position appears to be the brake position. or the speed control clicks off and that brakes it…
This one isn’t quite the same but darn close.
(they soldered the display on, and there is a board number on the amazon one.)

This guy did a review on it. You might be able to clean something from it. I don’t know.
