I would have to look inside a Tomb Stone to know for certain. A "Tap" location is the notch/point/location/contact where the electrical connection is changed. To obtain higher or lower voltages.
Anyway, won’t a given amount of current create increasing amounts of heat as the size of the conductor carrying it decreases? ( Yes )
If all the conductors were the same gauge of wire then the amount of heat generated by resistance would increase as increasing amounts of current were conducted from the transformer to the work lead.( Yes )
In that case, the duty cycle would increase as the current decreased.( Yes )
But with the conductors increasing in size from the lowest tapped current to the highest, couldn’t the heat generated by resistance stay relatively consistent over the whole range? ( Yes)
This would then hold the duty cycle constant at all settings. ( Yes, but...........)
In this application the primary 240V windings appear to be limiting max power out.
