If the power ON LED does not illuminate on your Hypertherm Cutter when the power switch is ON, check the following: * Make sure the power cord is properly plugged into the receptacle. * Confirm that the power is on at the main power panel or disconnect-power switch box. * Verify that the line voltage is not too low (more than 15% below the rated voltage).
