Welcome to ASME.
Voltage, amperage, and travel speed are considered to be nonessential variables, as such they do not have to be recorded on the PQR.
When heat input is required for notch toughness, those variables are to calculate the heat input. If you know the equation for heat input, you can derive the travel speed.
Q = (I x E x 60)/V or volts x amps x 60 / travel speed.
