I hear what you saying but my machine doesn't work like that . I also see on you tube when Jody does his videos how he sets the knob to a certain current and the pedal still works like normal but maxes out where his set the knob .which is fine and convenient that some machines come with that but we don't have that in most machines in south africa or alteast I have not seen any with it so this is why I am asking about this . You know in America the have a.c balance in our country most machines say clean area width now as I understand it it's the same thing but makes things confusing when we watch American videos and you have fancy terms for things then we scratch our heads wondering what that is
