Re: AMPS SELECTION IN MPI If I understand you are using PROD TECHNIQUE, you may use ASTM E1444 fo rmaterial UP to 3/4" 90-115 Amp/in of prod spacing, For materials graeter that 3/4" 100-125 Amp/ in of prod spacing, You may use also a QQI to verify if the selected amperage is giving the magnetic field strenght you are requiring. keep in mind that MAx prod spacing is 8 in.
Hope it works
