I heard that keeping your frequency low puts more heat into the metal than having the frequency high.

Is this true and if so how is this happening?

Yea it does have that effect. This is because there are fewer crossings of the 0V point with a lower AC frequency. No "square wave" is an actual perfect square wave, and will ultimately have a certain slope (as opposed to an un-defined slope where the "line" is perfectly vertical) as it switches polarity. During the brief time it slopes up/down the heat delivered is less than what is delivered when the waveform is at the peak.

In my understanding it's true.

Think of higher frequency meaning more of the zero crossing points - cross enough times and the net effect should be less overall amperage getting to the metal.

Edit: I see Oscar got ya covered :)
