Used this to replace a bad wire feed motor driver board on a Harbor Freight Mig170 welder. I secured the old board out of the way with wire ties as it has other circuitry on it that still works. I installed this board using the potentiometer nut in the original hole. I installed a 24vdc power supply (240vac rated) to the pains terminals and wired the output in series with the trigger wire. It fed wire perfectly and brought the welder back to operation. I did add some hot glue to support the board and prevent it from touching anything. It is nice that it has a heat sink to keep it cool as the original one did not. Great little board and appears to be well built.
