Question about Miller Electric Mfg Co 903394 Deltaweld 452 MIG Welder, 3- Phase, 15 - 38 V
Try replacing the potentiometer, this is the variable dial which alters the speed. It should show the value in ohms on the back of the case, these are relatively cheap and can be bought from RS. Its sound like the wiper in the dial is loose.
