If a simple voltmeter on the DC scale is being used to measure the voltage, then it's not likely to be registering the peak voltage in a pulsed setup, so while it might appear that lower pulsed voltages result in gas formation, it's possible that the gas is actually only being produced during the actual peak of the pulse, where it exceeds ~ 1.2 V.
