I am using volts only to control my torch height but when the torch fires the DOR for amps goes to 255 and stays there.  This is making my torch jump up as soon as it is fired.  Is there a way I can ignore this input or force it to zero?  I have changed the torch control card and cables but there is no change.  I can turn the THC off at the begging of the cut then turn it on after it starts and everything works.  The DOR for amps still reads 255 but it works off of volts.
