This is the second batch of these little PWM controllers I have bought from BG. I've used them in modifying small and cheap welding machines to give a more stable control of the welding wire feed speed. They work perfectly in this role and are very simple to fit. The lowest and highest speed is easily altered by soldering small resistors to the pot end connections so the range of usable speed can be spread over the range of the pot adjustment. I am very pleased with these units and at the price I don't think there is a better solution for my needs.
